Settings Reference

Introduction

Horizon's settings broadly fall into three categories:

General Settings: this includes visual settings like the modal backdrop style, bug url and theme configuration, as well as settings that affect every service, such as page sizes on API requests.
Service-specific Settings: Many services that Horizon consumes, such as Nova and Neutron, don't advertise their capabilities via APIs, so Horizon carries configuration for operators to enable or disable many items. This section covers all settings that are specific to a single service.
Django Settings, which are common to all Django applications. The only ones documented here are those that Horizon alters by default; however, you should read the Django settings documentation to see the other options available to you.

To modify your settings, you have two options:

Preferred: Add .py settings snippets to the openstack_dashboard/local/local_settings.d/ directory. Several example files (appended with .example) can be found there. These must start with an underscore, and are evaluated alphabetically, after local_settings.py.
Modify your openstack_dashboard/local/local_settings.py. There is an file found at openstack_dashboard/local/local_settings.py.example.

General Settings

ANGULAR_FEATURES

10.0.0(Newton)

Default:

{
    'images_panel': True,
    'key_pairs_panel': True,
    'flavors_panel': False,
    'domains_panel': False,
    'users_panel': False,
    'groups_panel': False,
    'roles_panel': True
}

A dictionary of currently available AngularJS features. This allows simple toggling of legacy or rewritten features, such as new panels, workflows etc.

Note

If you toggle domains_panel to True, you also need to enable the setting of OPENSTACK_KEYSTONE_DEFAULT_DOMAIN and add OPENSTACK_KEYSTONE_DEFAULT_DOMAIN to REST_API_REQUIRED_SETTINGS.

API_RESULT_LIMIT

2012.1(Essex)

Default: 1000

The maximum number of objects (e.g. Swift objects or Glance images) to display on a single page before providing a paging element (a "more" link) to paginate results.

API_RESULT_PAGE_SIZE

2012.2(Folsom)

Default: 20

Similar to API_RESULT_LIMIT. This setting controls the number of items to be shown per page if API pagination support for this exists.

AVAILABLE_THEMES

9.0.0(Mitaka)

Default:

AVAILABLE_THEMES = [
     ('default', 'Default', 'themes/default'),
     ('material', 'Material', 'themes/material'),
]

This setting tells Horizon which themes to use.

A list of tuples which define multiple themes. The tuple format is ('{{ theme_name }}', '{{ theme_label }}', '{{ theme_path }}').

The theme_name is the name used to define the directory which the theme is collected into, under /{{ THEME_COLLECTION_DIR }}. It also specifies the key by which the selected theme is stored in the browser's cookie.

The theme_label is the user-facing label that is shown in the theme picker. The theme picker is only visible if more than one theme is configured, and shows under the topnav's user menu.

By default, the theme path is the directory that will serve as the static root of the theme and the entire contents of the directory is served up at /{{ THEME_COLLECTION_DIR }}/{{ theme_name }}. If you wish to include content other than static files in a theme directory, but do not wish that content to be served up, then you can create a sub directory named static. If the theme folder contains a sub-directory with the name static, then static/custom/static will be used as the root for the content served at /static/custom.

The static root of the theme folder must always contain a _variables.scss file and a _styles.scss file. These must contain or import all the bootstrap and horizon specific variables and styles which are used to style the GUI. For example themes, see: /horizon/openstack_dashboard/themes/

Horizon ships with two themes configured. 'default' is the default theme, and 'material' is based on Google's Material Design.

DEFAULT_THEME

9.0.0(Mitaka)

Default: "default"

This setting tells Horizon which theme to use if the user has not yet selected a theme through the theme picker and therefore set the cookie value. This value represents the theme_name key that is used from AVAILABLE_THEMES. To use this setting, the theme must also be configured inside of AVAILABLE_THEMES. Your default theme must be configured as part of SELECTABLE_THEMES. If it is not, then your DEFAULT_THEME will default to the first theme in SELECTABLE_THEMES.

DISALLOW_IFRAME_EMBED

8.0.0(Liberty)

Default: True

This setting can be used to defend against Clickjacking and prevent Horizon from being embedded within an iframe. Legacy browsers are still vulnerable to a Cross-Frame Scripting (XFS) vulnerability, so this option allows extra security hardening where iframes are not used in deployment. When set to true, a "frame-buster" script is inserted into the template header that prevents the web page from being framed and therefore defends against clickjacking.

For more information see: http://tinyurl.com/anticlickjack

Note

If your deployment requires the use of iframes, you can set this setting to False to exclude the frame-busting code and allow iframe embedding.

DROPDOWN_MAX_ITEMS

2015.1(Kilo)

Default: 30

This setting sets the maximum number of items displayed in a dropdown. Dropdowns that limit based on this value need to support a way to observe the entire list.

FILTER_DATA_FIRST

10.0.0(Newton)

Default:

{
    'admin.instances': False,
    'admin.images': False,
    'admin.networks': False,
    'admin.routers': False,
    'admin.volumes': False
}

If the dict key-value is True, when the view loads, an empty table will be rendered and the user will be asked to provide a search criteria first (in case no search criteria was provided) before loading any data.

Examples:

Override the dict:

{
    'admin.instances': True,
    'admin.images': True,
    'admin.networks': False,
    'admin.routers': False,
    'admin.volumes': False
}

Or, if you want to turn this on for an specific panel/view do:

FILTER_DATA_FIRST['admin.instances'] = True

HORIZON_CONFIG

A dictionary of some Horizon configuration values. These are primarily separated for historic design reasons.

Default:

HORIZON_CONFIG = {
    'user_home': 'openstack_dashboard.views.get_user_home',
    'ajax_queue_limit': 10,
    'auto_fade_alerts': {
        'delay': 3000,
        'fade_duration': 1500,
        'types': [
            'alert-success',
            'alert-info'
        ]
    },
    'bug_url': None,
    'help_url': "https://docs.openstack.org/",
    'exceptions': {
        'recoverable': exceptions.RECOVERABLE,
        'not_found': exceptions.NOT_FOUND,
        'unauthorized': exceptions.UNAUTHORIZED
    },
    'modal_backdrop': 'static',
    'angular_modules': [],
    'js_files': [],
    'js_spec_files': [],
    'external_templates': [],
}

ajax_poll_interval

2012.1(Essex)

Default: 2500

How frequently resources in transition states should be polled for updates, expressed in milliseconds.

ajax_queue_limit

2012.1(Essex)

Default: 10

The maximum number of simultaneous AJAX connections the dashboard may try to make. This is particularly relevant when monitoring a large number of instances, volumes, etc. which are all actively trying to update/change state.

angular_modules

2014.2(Juno)

Default: []

A list of AngularJS modules to be loaded when Angular bootstraps. These modules are added as dependencies on the root Horizon application horizon.

auto_fade_alerts

2013.2(Havana)

Default:

{
    'delay': 3000,
    'fade_duration': 1500,
    'types': []
}

If provided, will auto-fade the alert types specified. Valid alert types include: ['alert-default', 'alert-success', 'alert-info', 'alert-warning', 'alert-danger'] Can also define the delay before the alert fades and the fade out duration.

bug_url

9.0.0(Mitaka)

Default: None

If provided, a "Report Bug" link will be displayed in the site header which links to the value of this setting (ideally a URL containing information on how to report issues).

disable_password_reveal

2015.1(Kilo)

Default: False

Setting this to True will disable the reveal button for password fields, including on the login form.

exceptions

2012.1(Essex)

Default:

{
    'unauthorized': [],
    'not_found': [],
    'recoverable': []
}

A dictionary containing classes of exceptions which Horizon's centralized exception handling should be aware of. Based on these exception categories, Horizon will handle the exception and display a message to the user.

help_url

2012.2(Folsom)

Default: None

If provided, a "Help" link will be displayed in the site header which links to the value of this setting (ideally a URL containing help information).

js_files

2014.2(Juno)

Default: []

A list of javascript source files to be included in the compressed set of files that are loaded on every page. This is needed for AngularJS modules that are referenced in angular_modules and therefore need to be include in every page.

js_spec_files

2015.1(Kilo)

Default: []

A list of javascript spec files to include for integration with the Jasmine spec runner. Jasmine is a behavior-driven development framework for testing JavaScript code.

modal_backdrop

2014.2(Kilo)

Default: "static"

Controls how bootstrap backdrop element outside of modals looks and feels. Valid values are "true" (show backdrop element outside the modal, close the modal after clicking on backdrop), "false" (do not show backdrop element, do not close the modal after clicking outside of it) and "static" (show backdrop element outside the modal, do not close the modal after clicking on backdrop).

password_autocomplete

2013.1(Grizzly)

Default: "off"

Controls whether browser autocompletion should be enabled on the login form. Valid values are "on" and "off".

password_validator

2012.1(Essex)

Default:

{
    'regex': '.*',
    'help_text': _("Password is not accepted")
}

A dictionary containing a regular expression which will be used for password validation and help text which will be displayed if the password does not pass validation. The help text should describe the password requirements if there are any.

This setting allows you to set rules for passwords if your organization requires them.

user_home

2012.1(Essex)

Default: settings.LOGIN_REDIRECT_URL

This can be either a literal URL path (such as the default), or Python's dotted string notation representing a function which will evaluate what URL a user should be redirected to based on the attributes of that user.

MESSAGES_PATH

9.0.0(Mitaka)

Default: None

The absolute path to the directory where message files are collected.

When the user logins to horizon, the message files collected are processed and displayed to the user. Each message file should contain a JSON formatted data and must have a .json file extension. For example:

{
    "level": "info",
    "message": "message of the day here"
}

Possible values for level are: success, info, warning and error.

NG_TEMPLATE_CACHE_AGE

10.0.0(Newton)

Angular Templates are cached using this duration (in seconds) if DEBUG is set to False. Default value is 2592000 (or 30 days).

OPENSTACK_API_VERSIONS

2013.2(Havana)

Default:

{
    "data-processing": 1.1,
    "identity": 3,
    "volume": 2,
    "compute": 2
}

Overrides for OpenStack API versions. Use this setting to force the OpenStack dashboard to use a specific API version for a given service API.

Note

The version should be formatted as it appears in the URL for the service API. For example, the identity service APIs have inconsistent use of the decimal point, so valid options would be "2.0" or "3". For example:

OPENSTACK_API_VERSIONS = {
    "data-processing": 1.1,
    "identity": 3,
    "volume": 2,
    "compute": 2
}

OPENSTACK_CLOUDS_YAML_NAME

12.0.0(Pike)

Default: "openstack"

The name of the entry to put into the user's clouds.yaml file.

OPENSTACK_CLOUDS_YAML_PROFILE

12.0.0(Pike)

Default: None

If set, the name of the vendor profile from os-client-config.

OPENSTACK_ENDPOINT_TYPE

2012.1(Essex)

Default: "publicURL"

A string which specifies the endpoint type to use for the endpoints in the Keystone service catalog. The default value for all services except for identity is "publicURL" . The default value for the identity service is "internalURL".

OPENSTACK_HOST

2012.1(Essex)

Default: "127.0.0.1"

The hostname of the Keystone server used for authentication if you only have one region. This is often the only setting that needs to be set for a basic deployment.

If you have multiple regions you should use the AVAILABLE_REGIONS setting instead.

OPENSTACK_PROFILER

11.0.0(Ocata)

Default: {"enabled": False}

Various settings related to integration with osprofiler library. Since it is a developer feature, it starts as disabled. To enable it, more than a single "enabled" key should be specified. Additional keys that should be specified in that dictionary are:

"keys" is a list of strings, which are secret keys used to encode/decode the profiler data contained in request headers. Encryption is used for security purposes, other OpenStack components that are expected to profile themselves with osprofiler using the data from the request that Horizon initiated must share a common set of keys with the ones in Horizon config. List of keys is used so that security keys could be changed in non-obtrusive manner for every component in the cloud. Example: "keys": ["SECRET_KEY", "MORE_SECRET_KEY"]. For more details see osprofiler documentation.
"notifier_connection_string" is a url to which trace messages are sent by Horizon. For other components it is usually the only URL specified in config, because other components act mostly as traces producers. Example: "notifier_connection_string": "mongodb://%s' % OPENSTACK_HOST".
"receiver_connection_string" is a url from which traces are retrieved by Horizon, needed because Horizon is not only the traces producer, but also a consumer. Having 2 settings which usually contain the same value is legacy feature from older versions of osprofiler when OpenStack components could use oslo.messaging for notifications and the trace client used ceilometer as a receiver backend. By default Horizon uses the same URL pointing to a MongoDB cluster for both purposes, since ceilometer was too slow for using with UI. Example: "receiver_connection_string": "mongodb://%s" % OPENSTACK_HOST.

OPENSTACK_SSL_CACERT

2013.2(Havana)

Default: None

When unset or set to None the default CA certificate on the system is used for SSL verification.

When set with the path to a custom CA certificate file, this overrides use of the default system CA certificate. This custom certificate is used to verify all connections to openstack services when making API calls.

OPENSTACK_SSL_NO_VERIFY

2012.2(Folsom)

Default: False

Disable SSL certificate checks in the OpenStack clients (useful for self-signed certificates).

OPERATION_LOG_ENABLED

10.0.0(Newton)

Default: False

This setting can be used to enable logging of all operations carried out by users of Horizon. The format of the logs is configured via OPERATION_LOG_OPTIONS

Note

If you use this feature, you need to configure the logger setting like a outputting path for operation log in local_settings.py.

OPERATION_LOG_OPTIONS

10.0.0(Newton)

12.0.0(Pike)

Added ignored_urls parameter and added %(client_ip)s to format

Default:

{
    'mask_fields': ['password'],
    'target_methods': ['POST'],
    'ignored_urls': ['/js/', '/static/', '^/api/'],
    'format': ("[%(domain_name)s] [%(domain_id)s] [%(project_name)s]"
        " [%(project_id)s] [%(user_name)s] [%(user_id)s] [%(request_scheme)s]"
        " [%(referer_url)s] [%(request_url)s] [%(message)s] [%(method)s]"
        " [%(http_status)s] [%(param)s]"),
}

This setting controls the behavior of the operation log.

mask_fields is a list of keys of post data which should be masked from the point of view of security. Fields like password should be included. The fields specified in mask_fields are logged as ********.
target_methods is a request method which is logged to a operation log. The valid methods are POST, GET, PUT, DELETE.
ignored_urls is a list of request URLs to be hidden from a log.
format defines the operation log format. Currently you can use the following keywords. The default value contains all keywords.
- %(client_ip)s
- %(domain_name)s
- %(domain_id)s
- %(project_name)s
- %(project_id)s
- %(user_name)s
- %(user_id)s
- %(request_scheme)s
- %(referer_url)s
- %(request_url)s
- %(message)s
- %(method)s
- %(http_status)s
- %(param)s

OVERVIEW_DAYS_RANGE

10.0.0(Newton)

Default:: 1

When set to an integer N (as by default), the start date in the Overview panel meters will be today minus N days. This setting is used to limit the amount of data fetched by default when rendering the Overview panel. If set to None (which corresponds to the behavior in past Horizon versions), the start date will be from the beginning of the current month until the current date. The legacy behaviour is not recommended for large deployments as Horizon suffers significant lag in this case.

POLICY_CHECK_FUNCTION

2013.2(Havana)

Default:: openstack_auth.policy.check

This value should not be changed, although removing it or setting it to None would be a means to bypass all policy checks.

POLICY_DIRS

13.0.0(Queens)

Default:

{
    'compute': ['nova_policy.d'],
    'volume': ['cinder_policy.d'],
}

Specifies a list of policy directories per service types. The directories are relative to POLICY_FILES_PATH. Services whose additional policies are defined here must be defined in POLICY_FILES too. Otherwise, additional policies specified in POLICY_DIRS are not loaded.

Note

cinder_policy.d and nova_policy.d are registered by default to maintain policies which have ben dropped from nova and cinder but horizon still uses. We recommend not to drop them.

POLICY_FILES

2013.2(Havana)

Default:

{
    'compute': 'nova_policy.json',
    'identity': 'keystone_policy.json',
    'image': 'glance_policy.json',
    'network': 'neutron_policy.json',
    'volume': 'cinder_policy.json',
}

This should essentially be the mapping of the contents of POLICY_FILES_PATH to service types. When policy.json files are added to POLICY_FILES_PATH, they should be included here too.

POLICY_FILES_PATH

2013.2(Havana)

Default: os.path.join(ROOT_PATH, "conf")

Specifies where service based policy files are located. These are used to define the policy rules actions are verified against.

REST_API_REQUIRED_SETTINGS

2014.2(Kilo)

Default:

[
    'OPENSTACK_HYPERVISOR_FEATURES',
    'LAUNCH_INSTANCE_DEFAULTS',
    'OPENSTACK_IMAGE_FORMATS',
    'OPENSTACK_KEYSTONE_DEFAULT_DOMAIN'
]

This setting allows you to expose configuration values over Horizons internal REST API, so that the AngularJS panels can access them. Please be cautious about which values are listed here (and thus exposed on the frontend)

SELECTABLE_THEMES

12.0.0(Pike)

Default: AVAILABLE_THEMES

This setting tells Horizon which themes to expose to the user as selectable in the theme picker widget. This value defaults to all themes configured in AVAILABLE_THEMES, but a brander may wish to simply inherit from an existing theme and not allow that parent theme to be selected by the user. SELECTABLE_THEMES takes the exact same format as AVAILABLE_THEMES.

SESSION_TIMEOUT

2013.2(Havana)

Default: "3600"

This SESSION_TIMEOUT is a method to supercede the token timeout with a shorter horizon session timeout (in seconds). So if your token expires in 60 minutes, a value of 1800 will log users out after 30 minutes.

SHOW_KEYSTONE_V2_RC

13.0.0(Queens)

Default: True

Controls whether the keystone v2 openrc file is accessable from the user menu and the api access panel.

THEME_COLLECTION_DIR

9.0.0(Mitaka)

Default: "themes"

This setting tells Horizon which static directory to collect the available themes into, and therefore which URL points to the theme collection root. For example, the default theme would be accessible via /{{ STATIC_URL }}/themes/default.

THEME_COOKIE_NAME

9.0.0(Mitaka)

Default: "theme"

This setting tells Horizon in which cookie key to store the currently set theme. The cookie expiration is currently set to a year.

USER_MENU_LINKS

13.0.0(Queens)

Default:

[
  {'name': _('OpenStack RC File v2'),
   'icon_classes': ['fa-download', ],
   'url': 'horizon:project:api_access:openrcv2',
   'external': False,
   },
  {'name': _('OpenStack RC File v3'),
   'icon_classes': ['fa-download', ],
   'url': 'horizon:project:api_access:openrc',
   'external': False,
   }
]

This setting controls the additional links on the user drop down menu. A list of dictionaries defining all of the links should be provided. This defaults to the standard OpenStack RC files.

Each dictionary should contain these values:

name: The name of the link
url: Either the reversible Django url name or an absolute url
external: True for absolute URLs, False for django urls.
icon_classes: A list of classes for the icon next to the link. If 'None' or an empty list is provided a download icon will show

WEBROOT

2015.1(Kilo)

Default: "/"

Specifies the location where the access to the dashboard is configured in the web server.

For example, if you're accessing the Dashboard via https://<your server>/dashboard, you would set this to "/dashboard/".

Note

Additional settings may be required in the config files of your webserver of choice. For example to make "/dashboard/" the web root in Apache, the "sites-available/horizon.conf" requires a couple of additional aliases set:

Alias /dashboard/static %HORIZON_DIR%/static

Alias /dashboard/media %HORIZON_DIR%/openstack_dashboard/static

Apache also requires changing your WSGIScriptAlias to reflect the desired path. For example, you'd replace / with /dashboard for the alias.

Service-specific Settings

The following settings inform the OpenStack Dashboard of information about the other OpenStack projects which are part of this cloud and control the behavior of specific dashboards, panels, API calls, etc.

Cinder

OPENSTACK_CINDER_FEATURES

2014.2(Juno)

Default: {'enable_backup': False}

A dictionary of settings which can be used to enable optional services provided by cinder. Currently only the backup service is available.

Glance

CREATE_IMAGE_DEFAULTS

12.0.0(Pike)

Default:

{
    'image_visibility': "public",
}

A dictionary of default settings for create image modal.

The image_visibility setting specifies the default visibility option. Valid values are "public" and "private". By default, the visibility option is public on create image modal. If it's set to "private", the default visibility option is private.

HORIZON_IMAGES_UPLOAD_MODE

10.0.0(Newton)

Default: "legacy"

Valid values are "direct", "legacy" (default) and "off". "off" disables the ability to upload images via Horizon. legacy enables local file upload by piping the image file through the Horizon's web-server. direct sends the image file directly from the web browser to Glance. This bypasses Horizon web-server which both reduces network hops and prevents filling up Horizon web-server's filesystem. direct is the preferred mode, but due to the following requirements it is not the default. The direct setting requires a modern web browser, network access from the browser to the public Glance endpoint, and CORS support to be enabled on the Glance API service. Without CORS support, the browser will forbid the PUT request to a location different than the Horizon server. To enable CORS support for Glance API service, you will need to edit [cors] section of glance-api.conf file (see here how to do it). Set allowed_origin to the full hostname of Horizon web-server (e.g. http://<HOST_IP>/dashboard) and restart glance-api process.

IMAGE_CUSTOM_PROPERTY_TITLES

2014.1(Icehouse)

Default:

{
    "architecture": _("Architecture"),
    "kernel_id": _("Kernel ID"),
    "ramdisk_id": _("Ramdisk ID"),
    "image_state": _("Euca2ools state"),
    "project_id": _("Project ID"),
    "image_type": _("Image Type")
}

Used to customize the titles for image custom property attributes that appear on image detail pages.

IMAGE_RESERVED_CUSTOM_PROPERTIES

2014.2(Juno)

Default: []

A list of image custom property keys that should not be displayed in the Update Metadata tree.

This setting can be used in the case where a separate panel is used for managing a custom property or if a certain custom property should never be edited.

IMAGES_ALLOW_LOCATION

10.0.0(Newton)

Default: False

If set to True, this setting allows users to specify an image location (URL) as the image source when creating or updating images. Depending on the Glance version, the ability to set an image location is controlled by policies and/or the Glance configuration. Therefore IMAGES_ALLOW_LOCATION should only be set to True if Glance is configured to allow specifying a location. This setting has no effect when the Keystone catalog doesn't contain a Glance v2 endpoint.

IMAGES_LIST_FILTER_TENANTS

2013.1(Grizzly)

Default: None

A list of dictionaries to add optional categories to the image fixed filters in the Images panel, based on project ownership.

Each dictionary should contain a tenant attribute with the project id, and optionally a text attribute specifying the category name, and an icon attribute that displays an icon in the filter button. The icon names are based on the default icon theme provided by Bootstrap.

Example:

[{'text': 'Official',
  'tenant': '27d0058849da47c896d205e2fc25a5e8',
  'icon': 'fa-check'}]

OPENSTACK_IMAGE_BACKEND

2013.2(Havana)

Default:

{
    'image_formats': [
        ('', _('Select format')),
        ('aki', _('AKI - Amazon Kernel Image')),
        ('ami', _('AMI - Amazon Machine Image')),
        ('ari', _('ARI - Amazon Ramdisk Image')),
        ('docker', _('Docker')),
        ('iso', _('ISO - Optical Disk Image')),
        ('qcow2', _('QCOW2 - QEMU Emulator')),
        ('raw', _('Raw')),
        ('vdi', _('VDI')),
        ('vhd', _('VHD')),
        ('vmdk', _('VMDK'))
    ]
}

Used to customize features related to the image service, such as the list of supported image formats.

Keystone

AUTHENTICATION_PLUGINS

2015.1(Kilo)

Default:

[
    'openstack_auth.plugin.password.PasswordPlugin',
    'openstack_auth.plugin.token.TokenPlugin'
]

A list of authentication plugins to be used. In most cases, there is no need to configure this.

AUTHENTICATION_URLS

2015.1(Kilo)

Default: ['openstack_auth.urls']

A list of modules from which to collate authentication URLs from. The default option adds URLs from the django-openstack-auth module however others will be required for additional authentication mechanisms.

AVAILABLE_REGIONS

2012.1(Essex)

Default: None

A list of tuples which define multiple regions. The tuple format is ('http://{{ keystone_host }}:5000/v3', '{{ region_name }}'). If any regions are specified the login form will have a dropdown selector for authenticating to the appropriate region, and there will be a region switcher dropdown in the site header when logged in.

You should also define OPENSTACK_KEYSTONE_URL to indicate which of the regions is the default one.

DEFAULT_SERVICE_REGIONS

12.0.0(Pike)

Default: {}

The default service region is set on a per-endpoint basis, meaning that once the user logs into some Keystone endpoint, if a default service region is defined for it in this setting and exists within Keystone catalog, it will be set as the initial service region in this endpoint. By default it is an empty dictionary because upstream can neither predict service region names in a specific deployment, nor tell whether this behavior is desired. The key of the dictionary is a full url of a Keystone endpoint with version suffix, the value is a region name.

Example:

DEFAULT_SERVICE_REGIONS = {
    OPENSTACK_KEYSTONE_URL: 'RegionOne'
}

ENABLE_CLIENT_TOKEN

10.0.0(Newton)

Default: True

This setting will Enable/Disable access to the Keystone Token to the browser.

ENFORCE_PASSWORD_CHECK

2015.1(Kilo)

Default: False

This setting will display an 'Admin Password' field on the Change Password form to verify that it is indeed the admin logged-in who wants to change the password.

KEYSTONE_PROVIDER_IDP_ID

11.0.0(Ocata)

Default: "localkeystone"

This ID is only used for comparison with the service provider IDs. This ID should not match any service provider IDs.

KEYSTONE_PROVIDER_IDP_NAME

11.0.0(Ocata)

Default: "Local Keystone"

The Keystone Provider drop down uses Keystone to Keystone federation to switch between Keystone service providers. This sets the display name for the Identity Provider (dropdown display name).

OPENSTACK_KEYSTONE_ADMIN_ROLES

2015.1(Kilo)

Default: ["admin"]

The list of roles that have administrator privileges in this OpenStack installation. This check is very basic and essentially only works with keystone v2.0 and v3 with the default policy file. The setting assumes there is a common admin like role(s) across services. Example uses of this setting are:

to rename the admin role to cloud-admin
allowing multiple roles to have administrative privileges, like ["admin", "cloud-admin", "net-op"]

OPENSTACK_KEYSTONE_BACKEND

2012.1(Essex)

Default:

{
    'name': 'native',
    'can_edit_user': True,
    'can_edit_group': True,
    'can_edit_project': True,
    'can_edit_domain': True,
    'can_edit_role': True,
}

A dictionary containing settings which can be used to identify the capabilities of the auth backend for Keystone.

If Keystone has been configured to use LDAP as the auth backend then set can_edit_user and can_edit_project to False and name to "ldap".

OPENSTACK_KEYSTONE_DEFAULT_DOMAIN

2013.2(Havana)

Default: "Default"

Overrides the default domain used when running on single-domain model with Keystone V3. All entities will be created in the default domain.

OPENSTACK_KEYSTONE_DEFAULT_ROLE

2011.3(Diablo)

Default: "_member_"

The name of the role which will be assigned to a user when added to a project. This value must correspond to an existing role name in Keystone. In general, the value should match the member_role_name defined in keystone.conf.

OPENSTACK_KEYSTONE_DOMAIN_CHOICES

12.0.0(Pike)

Default:

(
    ('Default', 'Default'),
)

If OPENSTACK_KEYSTONE_DOMAIN_DROPDOWN is enabled, this option can be used to set the available domains to choose from. This is a list of pairs whose first value is the domain name and the second is the display name.

OPENSTACK_KEYSTONE_DOMAIN_DROPDOWN

12.0.0(Pike)

Default: False

Set this to True if you want available domains displayed as a dropdown menu on the login screen. It is strongly advised NOT to enable this for public clouds, as advertising enabled domains to unauthenticated customers irresponsibly exposes private information. This should only be used for private clouds where the dashboard sits behind a corporate firewall.

OPENSTACK_KEYSTONE_FEDERATION_MANAGEMENT

9.0.0(Mitaka)

Default: False

Set this to True to enable panels that provide the ability for users to manage Identity Providers (IdPs) and establish a set of rules to map federation protocol attributes to Identity API attributes. This extension requires v3.0+ of the Identity API.

OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT

2013.2(Havana)

Default: False

Set this to True if running on multi-domain model. When this is enabled, it will require user to enter the Domain name in addition to username for login.

OPENSTACK_KEYSTONE_URL

2011.3(Diablo)

Horizon's OPENSTACK_HOST documentation

Default: "http://%s:5000/v3" % OPENSTACK_HOST

The full URL for the Keystone endpoint used for authentication. Unless you are using HTTPS, running your Keystone server on a nonstandard port, or using a nonstandard URL scheme you shouldn't need to touch this setting.

OPENSTACK_TOKEN_HASH_ALGORITHM

2014.2(Juno)

Default: "md5"

The hash algorithm to use for authentication tokens. This must match the hash algorithm that the identity (Keystone) server and the auth_token middleware are using. Allowed values are the algorithms supported by Python's hashlib library.

PASSWORD_EXPIRES_WARNING_THRESHOLD_DAYS

12.0.0(Pike)

Default: -1

Password will have an expiration date when using keystone v3 and enabling the feature. This setting allows you to set the number of days that the user will be alerted prior to the password expiration. Once the password expires keystone will deny the access and users must contact an admin to change their password. Setting this value to N days means the user will be alerted when the password expires in less than N+1 days. -1 disables the feature.

PROJECT_TABLE_EXTRA_INFO

10.0.0(Newton)

USER_TABLE_EXTRA_INFO for the equivalent setting on the Users table

Default: {}

Adds additional information for projects as extra attributes. Projects can have extra attributes as defined by Keystone v3. This setting allows those attributes to be shown in Horizon.

For example:

PROJECT_TABLE_EXTRA_INFO = {
    'phone_num': _('Phone Number'),
}

SECURE_PROXY_ADDR_HEADER

Default: False

If horizon is behind a proxy server and the proxy is configured, the IP address from request is passed using header variables inside the request. The header name depends on a proxy or a load-balancer. This setting specifies the name of the header with remote IP address. The main use is for authentication log (success or fail) displaing the IP address of the user. The commom value for this setting is HTTP_X_REAL_IP or HTTP_X_FORWARDED_FOR. If not present, then REMOTE_ADDR header is used. (REMOTE_ADDR is the field of Django HttpRequest object which contains IP address of the client.)

TOKEN_DELETION_DISABLED

10.0.0(Newton)

Default: False

This setting allows deployers to control whether a token is deleted on log out. This can be helpful when there are often long running processes being run in the Horizon environment.

TOKEN_TIMEOUT_MARGIN

Default: 0

A time margin in seconds to subtract from the real token's validity. An example use case is that the token can be valid once the middleware passed, and invalid (timed-out) during a view rendering and this generates authorization errors during the view rendering. By setting this value to a few seconds, you can avoid token expiration during a view rendering.

USER_TABLE_EXTRA_INFO

10.0.0(Newton)

PROJECT_TABLE_EXTRA_INFO for the equivalent setting on the Projects table

Default: {}

Adds additional information for users as extra attributes. Users can have extra attributes as defined by Keystone v3. This setting allows those attributes to be shown in Horizon.

For example:

USER_TABLE_EXTRA_INFO = {
    'phone_num': _('Phone Number'),
}

WEBSSO_CHOICES

2015.1(Kilo)

Default:

(
    ("credentials", _("Keystone Credentials")),
    ("oidc", _("OpenID Connect")),
    ("saml2", _("Security Assertion Markup Language"))
)

This is the list of authentication mechanisms available to the user. It includes Keystone federation protocols such as OpenID Connect and SAML, and also keys that map to specific identity provider and federation protocol combinations (as defined in WEBSSO_IDP_MAPPING). The list of choices is completely configurable, so as long as the id remains intact. Do not remove the credentials mechanism unless you are sure. Once removed, even admins will have no way to log into the system via the dashboard.

WEBSSO_ENABLED

2015.1(Kilo)

Default: False

Enables keystone web single-sign-on if set to True. For this feature to work, make sure that you are using Keystone V3 and Django OpenStack Auth V1.2.0 or later.

WEBSSO_IDP_MAPPING

8.0.0(Liberty)

Default: {}

A dictionary of specific identity provider and federation protocol combinations. From the selected authentication mechanism, the value will be looked up as keys in the dictionary. If a match is found, it will redirect the user to a identity provider and federation protocol specific WebSSO endpoint in keystone, otherwise it will use the value as the protocol_id when redirecting to the WebSSO by protocol endpoint.

Example:

WEBSSO_CHOICES =  (
    ("credentials", _("Keystone Credentials")),
    ("oidc", _("OpenID Connect")),
    ("saml2", _("Security Assertion Markup Language")),
    ("acme_oidc", "ACME - OpenID Connect"),
    ("acme_saml2", "ACME - SAML2")
)

WEBSSO_IDP_MAPPING = {
    "acme_oidc": ("acme", "oidc"),
    "acme_saml2": ("acme", "saml2")
}

Note

The value is expected to be a tuple formatted as: (<idp_id>, <protocol_id>)

WEBSSO_INITIAL_CHOICE

2015.1(Kilo)

Default: "credentials"

Specifies the default authentication mechanism. When user lands on the login page, this is the first choice they will see.

Neutron

ALLOWED_PRIVATE_SUBNET_CIDR

10.0.0(Newton)

Default:

{
    'ipv4': [],
    'ipv6': []
}

A dictionary used to restrict user private subnet CIDR range. An empty list means that user input will not be restricted for a corresponding IP version. By default, there is no restriction for both IPv4 and IPv6.

Example:

{
    'ipv4': [
        '192.168.0.0/16',
        '10.0.0.0/8'
    ],
    'ipv6': [
        'fc00::/7',
    ]
}

OPENSTACK_NEUTRON_NETWORK

2013.1(Grizzly)

Default:

{
    'default_dns_nameservers': [],
    'enable_distributed_router': False,
    'enable_fip_topology_check': True,
    'enable_ha_router': False,
    'enable_ipv6': True,
    'enable_quotas': False,
    'enable_router': True,
    'extra_provider_types': {},
    'physical_networks': [],
    'segmentation_id_range': {},
    'supported_provider_types': ["*"],
    'supported_vnic_types': ["*"],
}

A dictionary of settings which can be used to enable optional services provided by Neutron and configure Neutron specific features. The following options are available.

default_dns_nameservers

10.0.0(Newton)

Default: None (Empty)

Default DNS servers you would like to use when a subnet is created. This is only a default. Users can still choose a different list of dns servers.

Example: ["8.8.8.8", "8.8.4.4", "208.67.222.222"]

enable_distributed_router

2014.2(Juno)

Default: False

Enable or disable Neutron distributed virtual router (DVR) feature in the Router panel. For the DVR feature to be enabled, this option needs to be set to True and your Neutron deployment must support DVR. Even when your Neutron plugin (like ML2 plugin) supports DVR feature, DVR feature depends on l3-agent configuration, so deployers should set this option appropriately depending on your deployment.

enable_fip_topology_check

8.0.0(Liberty)

Default: True

The Default Neutron implementation needs a router with a gateway to associate a FIP. So by default a topology check will be performed by horizon to list only VM ports attached to a network which is itself attached to a router with an external gateway. This is to prevent from setting a FIP to a port which will fail with an error. Some Neutron vendors do not require it. Some can even attach a FIP to any port (e.g.: OpenContrail) owned by a tenant. Set to False if you want to be able to associate a FIP to an instance on a subnet with no router if your Neutron backend allows it.

enable_ha_router

2014.2(Juno)

Default: False

Enable or disable HA (High Availability) mode in Neutron virtual router in the Router panel. For the HA router mode to be enabled, this option needs to be set to True and your Neutron deployment must support HA router mode. Even when your Neutron plugin (like ML2 plugin) supports HA router mode, the feature depends on l3-agent configuration, so deployers should set this option appropriately depending on your deployment.

enable_ipv6

2014.2(Juno)

Default: False

Enable or disable IPv6 support in the Network panels. When disabled, Horizon will only expose IPv4 configuration for networks.

enable_quotas

Default: False

Enable support for Neutron quotas feature. To make this feature work appropriately, you need to use Neutron plugins with quotas extension support and quota_driver should be DbQuotaDriver (default config).

enable_router

2014.2(Juno)

Default: True

Enable (True) or disable (False) the panels and menus related to router and Floating IP features. This option only affects when Neutron is enabled. If your Neutron deployment has no support for Layer-3 features, or you do not wish to provide the Layer-3 features through the Dashboard, this should be set to False.

extra_provider_types

10.0.0(Newton)

Default: {}

For use with the provider network extension. This is a dictionary to define extra provider network definitions. Network types supported by Neutron depend on the configured plugin. Horizon has predefined provider network types but horizon cannot cover all of them. If you are using a provider network type not defined in advance, you can add a definition through this setting.

The key name of each item in this must be a network type used in the Neutron API. value should be a dictionary which contains the following items:

display_name: string displayed in the network creation form.
require_physical_network: a boolean parameter which indicates this network type requires a physical network.
require_segmentation_id: a boolean parameter which indicates this network type requires a segmentation ID. If True, a valid segmentation ID range must be configured in segmentation_id_range settings above.

Example:

{
    'awesome': {
        'display_name': 'Awesome',
        'require_physical_network': False,
        'require_segmentation_id': True,
    },
}

physical_networks

12.0.0(Pike)

Default: []

Default to an empty list and the physical network field on the admin create network modal will be a regular input field where users can type in the name of the physical network to be used. If it is set to a list of available physical networks, the physical network field will be shown as a dropdown menu where users can select a physical network to be used.

Example: ['default', 'test']

segmentation_id_range

2014.2(Juno)

Default: {}

For use with the provider network extension. This is a dictionary where each key is a provider network type and each value is a list containing two numbers. The first number is the minimum segmentation ID that is valid. The second number is the maximum segmentation ID. Pertains only to the vlan, gre, and vxlan network types. By default this option is not provided and each minimum and maximum value will be the default for the provider network type.

Example:

{
    'vlan': [1024, 2048],
    'gre': [4094, 65536]
}

supported_provider_types

2014.2(Juno)

Default: ["*"]

For use with the provider network extension. Use this to explicitly set which provider network types are supported. Only the network types in this list will be available to choose from when creating a network. Network types defined in Horizon or defined in extra_provider_types settings can be specified in this list. As of the Newton release, the network types defined in Horizon include network types supported by Neutron ML2 plugin with Open vSwitch driver (local, flat, vlan, gre, vxlan and geneve) and supported by Midonet plugin (midonet and uplink). ["*"] means that all provider network types supported by Neutron ML2 plugin will be available to choose from.

Example: ['local', 'flat', 'gre']

supported_vnic_types

2015.1(Kilo)

12.0.0(Pike)

Added virtio-forwarder VNIC type Clarified VNIC type availability for users and operators

Default ['*']

For use with the port binding extension. Use this to explicitly set which VNIC types are available for users to choose from, when creating or editing a port. The VNIC types actually supported are determined by resource availability and Neutron ML2 plugin support. Currently, error reporting for users selecting an incompatible or unavailable VNIC type is restricted to receiving a message from the scheduler that the instance cannot spawn because of insufficient resources. VNIC types include normal, direct, direct-physical, macvtap, baremetal and virtio-forwarder. By default all VNIC types will be available to choose from.

Example: ['normal', 'direct']

To disable VNIC type selection, set an empty list ([]) or None.

Nova

CREATE_INSTANCE_FLAVOR_SORT

2013.2(Havana)

Default:

{
    'key': 'ram'
}

When launching a new instance the default flavor is sorted by RAM usage in ascending order. You can customize the sort order by: id, name, ram, disk and vcpus. Additionally, you can insert any custom callback function. You can also provide a flag for reverse sort. See the description in local_settings.py.example for more information.

This example sorts flavors by vcpus in descending order:

CREATE_INSTANCE_FLAVOR_SORT = {
     'key':'vcpus',
     'reverse': True,
}

CONSOLE_TYPE

2013.2(Havana)

2014.2(Juno)

Added the None option, which deactivates the in-browser console

2015.1(Kilo)

Added the SERIAL option

2017.11(Queens)

Added the MKS option

Default: "AUTO"

This setting specifies the type of in-browser console used to access the VMs. Valid values are "AUTO", "VNC", "SPICE", "RDP", "SERIAL", "MKS", and None.

ENABLE_FLAVOR_EDIT

12.0.0(Pike)

Default: False

This setting enables the ability to edit flavors.

Warning

Historically, Horizon has provided the ability to edit Flavors by deleting and creating a new one with the same information. This is not supported in the Nova API and causes unexpected issues and breakages. To avoid breaking standard deprecation procedure, this code is still in Horizon, but disabled by default. It will be removed during the 14.0.0 ('R') release cycle.

See this email thread for further information.

INSTANCE_LOG_LENGTH

2015.1(Kilo)

Default: 35

This setting enables you to change the default number of lines displayed for the log of an instance. Valid value must be a positive integer.

LAUNCH_INSTANCE_DEFAULTS

9.0.0(Mitaka)

10.0.0(Newton)

Added the disable_image, disable_instance_snapshot, disable_volume and disable_volume_snapshot options.

12.0.0(Pike)

Added the create_volume option.

Default:

{
    "config_drive": False,
    "create_volume": True,
    "disable_image": False,
    "disable_instance_snapshot": False,
    "disable_volume": False,
    "disable_volume_snapshot": False,
    "enable_scheduler_hints": True,
}

A dictionary of settings which can be used to provide the default values for properties found in the Launch Instance modal. An explanation of each setting is provided below.

config_drive

9.0.0(Mitaka)

Default: False

This setting specifies the default value for the Configuration Drive property.

create_volume

12.0.0(Pike)

Default: True

This setting allows you to specify the default value for the option of creating a new volume in the workflow for image and instance snapshot sources.

disable_image

10.0.0(Newton)

Default: False

This setting disables Images as a valid boot source for launching instances. Image sources won't show up in the Launch Instance modal.

disable_instance_snapshot

10.0.0(Newton)

Default: False

This setting disables Snapshots as a valid boot source for launching instances. Snapshots sources won't show up in the Launch Instance modal.

disable_volume

10.0.0(Newton)

Default: False

This setting disables Volumes as a valid boot source for launching instances. Volumes sources won't show up in the Launch Instance modal.

disable_volume_snapshot

10.0.0(Newton)

Default: False

This setting disables Volume Snapshots as a valid boot source for launching instances. Volume Snapshots sources won't show up in the Launch Instance modal.

enable_scheduler_hints

9.0.0(Mitaka)

Default: True

This setting specifies whether or not Scheduler Hints can be provided when launching an instance.

LAUNCH_INSTANCE_LEGACY_ENABLED

8.0.0(Liberty)

9.0.0(Mitaka)

The default value for this setting has been changed to False

Default: False

This setting enables the Python Launch Instance workflow.

Note

It is possible to run both the AngularJS and Python workflows simultaneously, so the other may be need to be toggled with LAUNCH_INSTANCE_NG_ENABLED

LAUNCH_INSTANCE_NG_ENABLED

8.0.0(Liberty)

9.0.0(Mitaka)

The default value for this setting has been changed to True

Default: True

This setting enables the AngularJS Launch Instance workflow.

Note

It is possible to run both the AngularJS and Python workflows simultaneously, so the other may be need to be toggled with LAUNCH_INSTANCE_LEGACY_ENABLED

OPENSTACK_ENABLE_PASSWORD_RETRIEVE

2014.1(Icehouse)

Default: "False"

When set, enables the instance action "Retrieve password" allowing password retrieval from metadata service.

OPENSTACK_HYPERVISOR_FEATURES

2012.2(Folsom)

2014.1(Icehouse)

can_set_mount_point and can_set_password now default to False

Default:

{
    'can_set_mount_point': False,
    'can_set_password': False,
    'requires_keypair': False,
    'enable_quotas': True
}

A dictionary containing settings which can be used to identify the capabilities of the hypervisor for Nova.

The Xen Hypervisor has the ability to set the mount point for volumes attached to instances (other Hypervisors currently do not). Setting can_set_mount_point to True will add the option to set the mount point from the UI.

Setting can_set_password to True will enable the option to set an administrator password when launching or rebuilding an instance.

Setting requires_keypair to True will require users to select a key pair when launching an instance.

Setting enable_quotas to False will make Horizon treat all Nova quotas as disabled, thus it won't try to modify them. By default, quotas are enabled.

OPENSTACK_INSTANCE_RETRIEVE_IP_ADDRESSES

13.0.0(Queens)

Default: True

This settings controls whether IP addresses of servers are retrieved from neutron in the project instance table. Setting this to False may mitigate a performance issue in the project instance table in large deployments.

If your deployment has no support of floating IP like provider network scenario, you can set this to False in most cases. If your deployment supports floating IP, read the detail below and understand the under-the-hood before setting this to False.

Nova has a mechanism to cache network info but it is not fast enough in some cases. For example, when a user associates a floating IP or updates an IP address of an server port, it is not reflected to the nova network info cache immediately. This means an action which a user makes from the horizon instance table is not reflected into the table content just after the action. To avoid this, horizon retrieves IP address info from neutron when retrieving a list of servers from nova.

On the other hand, this operation requires a full list of neutron ports and can potentially lead to a performance issue in large deployments (bug 1722417). This issue can be avoided by skipping querying IP addresses to neutron and setting this to False achieves this. Note that when disabling the query to neutron it takes some time until associated floating IPs are visible in the project instance table and users may reload the table to check them.

OPENSTACK_NOVA_EXTENSIONS_BLACKLIST

8.0.0(Liberty)

Default: []

Ignore all listed Nova extensions, and behave as if they were unsupported. Can be used to selectively disable certain costly extensions for performance reasons.

Swift

SWIFT_FILE_TRANSFER_CHUNK_SIZE

2015.1(Kilo)

Default: 512 * 1024

This setting specifies the size of the chunk (in bytes) for downloading objects from Swift. Do not make it very large (higher than several dozens of Megabytes, exact number depends on your connection speed), otherwise you may encounter socket timeout. The default value is 524288 bytes (or 512 Kilobytes).

Django Settings

Note

This is not meant to be anywhere near a complete list of settings for Django. You should always consult the upstream documentation, especially with regards to deployment considerations and security best-practices.

ADD_INSTALLED_APPS

2015.1(Kilo)

Django's INSTALLED_APPS documentation

A list of Django applications to be prepended to the INSTALLED_APPS setting. Allows extending the list of installed applications without having to override it completely.

ALLOWED_HOSTS

2013.2(Havana)

Django's ALLOWED_HOSTS documentation

Default: ['localhost']

This list should contain names (or IP addresses) of the host running the dashboard; if it's being accessed via name, the DNS name (and probably short-name) should be added, if it's accessed via IP address, that should be added. The setting may contain more than one entry.

Note

ALLOWED_HOSTS is required. If Horizon is running in production (DEBUG is False), set this with the list of host/domain names that the application can serve. For more information see Django's Allowed Hosts documentation

DEBUG

2011.2(Cactus)

Django's DEBUG documentation

Default: True

Controls whether unhandled exceptions should generate a generic 500 response or present the user with a pretty-formatted debug information page.

When set, CACHED_TEMPLATE_LOADERS will not be cached.

This setting should always be set to False for production deployments as the debug page can display sensitive information to users and attackers alike.

SECRET_KEY

2012.1(Essex)

Django's SECRET_KEY documentation

This should absolutely be set to a unique (and secret) value for your deployment. Unless you are running a load-balancer with multiple Horizon installations behind it, each Horizon instance should have a unique secret key.

Note

Setting a custom secret key:

You can either set it to a specific value or you can let Horizon generate a default secret key that is unique on this machine, regardless of the amount of Python WSGI workers (if used behind Apache+mod_wsgi). However, there may be situations where you would want to set this explicitly, e.g. when multiple dashboard instances are distributed on different machines (usually behind a load-balancer). Either you have to make sure that a session gets all requests routed to the same dashboard instance or you set the same SECRET_KEY for all of them.

from horizon.utils import secret_key

SECRET_KEY = secret_key.generate_or_read_from_file(
os.path.join(LOCAL_PATH, '.secret_key_store'))

The local_settings.py.example file includes a quick-and-easy way to generate a secret key for a single installation.

STATIC_ROOT

8.0.0(Liberty)

Django's STATIC_ROOT documentation

Default: <path_to_horizon>/static

The absolute path to the directory where static files are collected when collectstatic is run.

STATIC_URL

8.0.0(Liberty)

Django's STATIC_URL documentation

Default: /static/

URL that refers to files in STATIC_ROOT.

By default this value is WEBROOT/static/.

This value can be changed from the default. When changed, the alias in your webserver configuration should be updated to match.

Note

The value for STATIC_URL must end in '/'.

This value is also available in the scss namespace with the variable name $static_url. Make sure you run python manage.py collectstatic and python manage.py compress after any changes to this value in settings.py.

TEMPLATES

10.0.0(Newton)

Django's TEMPLATES documentation

Horizon's usage of the TEMPLATES involves 3 further settings below; it is generally advised to use those before attempting to alter the TEMPLATES setting itself.

ADD_TEMPLATE_LOADERS

10.0.0(Newton)

Template loaders defined here will be loaded at the end of TEMPLATE_LOADERS, after the CACHED_TEMPLATE_LOADERS and will never have a cached output.

CACHED_TEMPLATE_LOADERS

10.0.0(Newton)

Template loaders defined here will have their output cached if DEBUG is set to False.

TEMPLATE_LOADERS

10.0.0(Newton)

These template loaders will be the first loaders and get loaded before the CACHED_TEMPLATE_LOADERS. Use ADD_TEMPLATE_LOADERS if you want to add loaders at the end and not cache loaded templates. After the whole settings process has gone through, TEMPLATE_LOADERS will be:

TEMPLATE_LOADERS += (
    ('django.template.loaders.cached.Loader', CACHED_TEMPLATE_LOADERS),
) + tuple(ADD_TEMPLATE_LOADERS)
