description: |
Network manager for the cloud; supports the following options:
.
FlatDHCPManager (nova-network) (default)
FlatManager (nova-network)
Neutron (Full SDN solution)
.
When using the Neutron option you will most likely want to use
the neutron-gateway charm to provide L3 routing and DHCP Services.

type: string
default: RegionOne
description: OpenStack Region
use-internal-endpoints:
type: boolean
default: False
description: |
Openstack mostly defaults to using public endpoints for internal
communication between services. If set to True this option will
configure services to use internal endpoints where possible.
ssl_cert:
type: string
default:
description: |
SSL certificate to install and use for API ports. Setting this value
and ssl_key will enable reverse proxying, point Nova's entry in the
Keystone catalog to use https, and override any certificate and key
issued by Keystone (if it is configured to do so).
ssl_key:
type: string
default:
description: SSL key to use with certificate specified as ssl_cert.
ssl_ca:
type: string
default:
description: |
SSL CA to use with the certificate and key provided - this is only
required if you are providing a privately signed ssl_cert and ssl_key.
service-guard:
type: boolean
default: false
description: |
Ensure required relations are made and complete before allowing services
to be started
.
By default, services may be up and accepting API request from install
onwards.
.
Enabling this flag ensures that services will not be started until the
minimum 'core relations' have been made between this charm and other
charms.
.
For this charm the following relations must be made:
.
* shared-db
* amqp
* identity-service
cache-known-hosts:
type: boolean
default: true
description: |
Caching is a strategy to reduce the hook execution time when
'cloud-compute' relation data changes.
.
If true, the charm will query the cache as needed and only perform a
lookup (and add a cache entry) when an entry is not available in the
cache.
.
If false, the charm will not query the cache, lookups will always be
performed, and the cache will be populated (or refreshed).
.
If there is a possibility that DNS resolution may change during a cloud
deployment then lookups may be inconsistent. In this case it may be
preferable to keep the option false and only change it to true post
deployment.
.
The 'clear-unit-knownhost-cache' action refreshes the cache (with forced
lookups) and updates the knownhost file on nova-compute units.
console-access-protocol:
type: string
default:
description: |
Protocol to use when accessing virtual machine console. Supported types
are None, spice, xvpvnc, novnc and vnc (for both xvpvnc and novnc).
.
NOTE: xvpvnc is not supported with bionic/ussuri or focal (or later)
releases.
console-access-port:
type: int
default:
description: |
Used to customize the console access port.
console-proxy-ip:

clients for access to console proxy. Set to local for the ip address of
the nova-cloud-controller serving the request to be used.
console-keymap:
type: string
default: 'en-us'
description: |
Console keymap.
console-ssl-cert:
type: string
default:
description: |
DEPRECATED: Please use ssl_cert configuration option or the vault
certificates relation. This configuration option will be removed
in the 19.07 charm release.
.
Used for encrypted console connections. This differs from the SSL
certificate used for API endpoints and is used for console sessions only.
Setting this value along with console-ssl-key will enable encrypted
console sessions. This has nothing to do with Nova API SSL and can be
used independently. This can be used in conjunction when
console-access-protocol is set to 'novnc' or 'spice'.
console-ssl-key:
type: string
default:
description: |
DEPRECATED: Please use ssl_key configuration option or the vault
certificates relation. This configuration option will be removed
in the 19.07 charm release.
.
SSL key to use with certificate specified as console-ssl-cert.
enable-serial-console:
type: boolean
default: false
description: |
Enable serial console access to instances using websockets (insecure).
This is only supported on OpenStack Juno or later, and will disable the
normal console-log output for an instance.
enable-new-services:
type: boolean
default: True
description: |
Enable new nova-compute services on this host automatically.
When a new nova-compute service starts up, it gets registered in the
database as an enabled service. Sometimes it can be useful to register
new compute services in disabled state and then enabled them at a later
point in time. This option only sets this behavior for nova-compute
services, it does not auto-disable other services like nova-conductor,
nova-scheduler, nova-consoleauth, or nova-osapi_compute.
Possible values: True: Each new compute service is enabled as soon as
it registers itself. False: Compute services must be enabled via an
os-services REST API call or with the CLI with
nova service-enable <hostname> <binary>, otherwise they are not ready
to use.
worker-multiplier:
type: float
default:
description: |
The CPU core multiplier to use when configuring worker processes for
this service. By default, the number of workers for each daemon is
set to twice the number of CPU cores a service unit has. This default
value will be capped to 4 workers unless this configuration option
is set.
cpu-allocation-ratio:
type: float
default: 2.0
description: |
The per physical core -> virtual core ratio to use in the Nova scheduler.
.
Increasing this value will increase instance density on compute nodes
at the expense of instance performance.
ram-allocation-ratio:
type: float
default: 0.98
description: |
The physical ram -> virtual ram ratio to use in the Nova scheduler.
.
Increasing this value will increase instance density on compute nodes
at the potential expense of instance performance.
.
NOTE: When in a hyper-converged architecture, make sure to make enough
room for infrastructure services running on your compute hosts by
adjusting this value.
disk-allocation-ratio:
type: float
default: 1.0
description: |
Increase the amount of disk space that nova can overcommit to guests.
.
Increasing this value will increase instance density on compute nodes
with an increased risk of hypervisor storage becoming full.
action-managed-upgrade:
type: boolean
default: False
description: |
If True enables openstack upgrades for this charm via juju actions.
You will still need to set openstack-origin to the new repository but
instead of an upgrade running automatically across all units, it will
wait for you to execute the openstack-upgrade action for this charm on
each unit. If False it will revert to existing behavior of upgrading
all units on config change.
scheduler-default-filters:
type: string
default:
description: |
List of filter class names to use for filtering hosts when not specified in
the request. The default filters varies based on OpenStack release.
pci-alias:
type: string
default:
description: |
The pci-passthrough-whitelist option of nova-compute charm is used for
specifying which PCI devices are allowed passthrough. pci-alias is more
a convenience that can be used in conjunction with Nova flavor properties
to automatically assign required PCI devices to new instances. You could,
for example, have a GPU flavor or a SR-IOV flavor:
.
pci-alias='{"vendor_id":"8086","product_id":"10ca","name":"a1"}'
.
This configures a new PCI alias 'a1' which will request a PCI device with
a vendor id of 0x8086 and a product id of 10ca.
.
For more information about the syntax of pci_alias, refer to
https://docs.openstack.org/ocata/config-reference/compute/config-options.html

type: string
default: unversioned
description: |
Specifies which notification format shall be used by nova-cloud-controller.
.
Starting in the Pike release, the notification_format includes both the
versioned and unversioned message notifications. Ceilometer does not yet
consume the versioned message notifications, so intentionally make the
default notification format unversioned until this is implemented.
.
Possible Values are both, versioned, unversioned.
cross-az-attach: # LP: 1856776
type: boolean
default: True # OpenStack default value
description: |
Allow attach between instance and volume in different availability zones.
.
If False, volumes attached to an instance must be in the same
availability zone in Cinder as the instance availability zone in Nova.
This also means care should be taken when booting an instance from a
volume where source is not "volume" because Nova will attempt to create
a volume using the same availability zone as what is assigned to the
instance.
.
If that AZ is not in Cinder, the volume create request will fail and the
instance will fail the build request.
.
By default there is no availability zone restriction on volume attach.
skip-hosts-with-build-failures: # LP: 1892934
type: boolean
default: False # LP: 1818239
description: |
Allow the scheduler to avoid building instances on hosts that had recent
build failures.
.
Since it is generally possible for an end user to cause build failures -
for example by providing a bad image - and maliciously reduce the pool of
available hypervisors, this option is disabled by default.
.
Enable to allow the scheduler to work around malfunctioning computes and
favor instance build reliability, at the cost of a potentially uneven
cloud utilization.
.
Note: only effective from Pike onward
limit-tenants-to-placement-aggregate:
type: boolean
default: False
description: |
This setting causes the scheduler to look up a host aggregate with the
metadata key of filter_tenant_id set to the project of an incoming
request, and request results from placement be limited to that
aggregate. Multiple tenants may be added to a single aggregate by
appending a serial number to the key, such as filter_tenant_id:123.
.
The matching aggregate UUID must be mirrored in placement for proper
operation. If no host aggregate with the tenant id is found, or that
aggregate does not match one in placement, the result will be the same
as not finding any suitable hosts for the request.
.
Set this option to True if you require instances for a particular tenant
to be placed in a particular host aggregate (i.e. a particular host or
set of hosts). After enabling this option, follow
https://docs.openstack.org/nova/latest/admin/aggregates.html#tenant-isolation-with-placement
for details on creating and configuring host aggregates and resource
providers.
.
Note that this will not prevent other tenants, who aren't associated with
a host aggregate, from launching instances on hosts within this
aggregate.
.
Also see the placement-aggregate-required-for-tenants and
enable-isolated-aggregate-filtering options.
.
This is only supported on OpenStack Train or later releases.
placement-aggregate-required-for-tenants:
type: boolean
default: False
description: |
This setting, which only has an effect when
limit-tenants-to-placement-aggregate is set to True, will control whether
or not a tenant with no aggregate affinity will be allowed to schedule to
any available node. If aggregates are used to limit some tenants but not
all, then this should be False. If all tenants should be confined via
aggregate, then this should be True to prevent them from receiving
unrestricted scheduling to any available node.
.
Set this option to True under the rare circumstance where you want to
manually control instance placement by associating every tenant with
a host aggregate. If you set this option to True and have tenants that
are not associated with a host aggregate, those tenants will no longer be
able to launch instances.
.
Also see the limit-tenants-to-placement-aggregate and
enable-isolated-aggregate-filtering options.
.
This is only supported on OpenStack Train or later releases.
enable-isolated-aggregate-filtering:
type: boolean
default: False
description: |
This setting allows the scheduler to restrict hosts in aggregates based
on matching required traits in the aggregate metadata and the instance
flavor/image. If an aggregate is configured with a property with key
trait:$TRAIT_NAME and value required, the instance flavor extra_specs
and/or image metadata must also contain trait:$TRAIT_NAME=required to be
eligible to be scheduled to hosts in that aggregate.
.
Set this option to True if you require that only instances with matching
traits (via flavor or image metadata) be placed on particular
hosts. This may also be a suitable workaround approach if you need to
give a tenant or tenants exclusivity for a compute host or set of hosts
(through the use of a custom trait) but otherwise want placement to
function normally for other hosts.
.
After enabling this option, follow
https://docs.openstack.org/nova/latest/reference/isolate-aggregates.html
for details on creating and creating and configuring traits, resource
providers and host aggregates.
.
Also see the limit-tenants-to-placement-aggregate and
placement-aggregate-required-for-tenants options.
.
This is only supported on OpenStack Train or later releases.
allow-resize-to-same-host:
type: boolean
default: False
description: |
Allow resizing to the same host. Setting this option to True will add the
source host to the destination options for consideration by the
scheduler when resizing an instance.
max-local-block-devices:
type: int
default:
description: |
Maximum number of local devices which can be attached to an
instance. Possible values are 0: Creating a local disk is not
allowed and letting the request fail, Negative number: Allows
unlimited number of local devices, Positive number: Allows only
these many number of local devices.
