openstack

OpenStack Command Line

SYNOPSIS

openstack [<global-options>] <command> [<command-arguments>]

openstack help <command>

openstack --help

DESCRIPTION

openstack provides a common command-line interface to OpenStack APIs. It is generally equivalent to the CLIs provided by the OpenStack project client libraries, but with a distinct and consistent command structure.

openstack uses a similar authentication scheme as the OpenStack project CLIs, with the credential information supplied either as environment variables or as options on the command line. The primary difference is the use of 'project' in the name of the options OS_PROJECT_NAME/OS_PROJECT_ID over the old tenant-based names.

export OS_AUTH_URL=<url-to-openstack-identity>
export OS_PROJECT_NAME=<project-name>
export OS_USERNAME=<user-name>
export OS_PASSWORD=<password>  # (optional)

OPTIONS

openstack takes global options that control overall behaviour and command-specific options that control the command operation. Most global options have a corresponding environment variable that may also be used to set the value. If both are present, the command-line option takes priority. The environment variable names are derived from the option name by dropping the leading dashes ('--'), converting each embedded dash ('-') to an underscore ('_'), and converting to upper case.

openstack recognizes the following global topions:

--os-auth-url <auth-url>

Authentication URL

--os-domain-name <auth-domain-name> | --os-domain-id <auth-domain-id>

Domain-level authorization scope (name or ID)

--os-project-name <auth-project-name> | --os-project-id <auth-project-id>

Project-level authentication scope (name or ID)

--os-project-domain-name <auth-project-domain-name> | --os-project-domain-id <auth-project-domain-id>

Domain name or id containing project

--os-username <auth-username>

Authentication username

--os-password <auth-password>

Authentication password

--os-user-domain-name <auth-user-domain-name> | --os-user-domain-id <auth-user-domain-id>

Domain name or id containing user

--os-user-domain-name <auth-user-domain-name> | --os-user-domain-id <auth-user-domain-id>

Domain name or ID containing user

--os-trust-id <trust-id>

id of the trust to use as a trustee user

--os-default-domain <auth-domain>

Default domain ID (Default: 'default')

--os-region-name <auth-region-name>

Authentication region name

--os-cacert <ca-bundle-file>

CA certificate bundle file

--verify | --insecure

Verify or ignore server certificate (default: verify)

--os-identity-api-version <identity-api-version>

Identity API version (Default: 2.0)

--os-XXXX-api-version <XXXX-api-version>

Additional API version options will be available depending on the installed API libraries.

COMMANDS

To get a list of the available commands:

openstack --help

To get a description of a specific command:

openstack help <command>

Note that the set of commands shown will vary depending on the API versions that are in effect at that time. For example, to force the display of the Identity v3 commands:

openstack --os-identity-api-version 3 --help

complete

Print the bash completion functions for the current command set.

help <command>

Print help for an individual command

Additional information on the OpenStackClient command structure and arguments is available in the OpenStackClient Commands wiki page.

Command Objects

The list of command objects is growing longer with the addition of OpenStack project support. The object names may consist of multiple words to compose a unique name. Occasionally when multiple APIs have a common name with common overlapping purposes there will be options to select which object to use, or the API resources will be merged, as in the quota object that has options referring to both Compute and Volume quotas.

Command Actions

The actions used by OpenStackClient are defined with specific meaning to provide a consistent behavior for each object. Some actions have logical opposite actions, and those pairs will always match for any object that uses them.

NOTES

The command list displayed in help output reflects the API versions selected. For example, to see Identity v3 commands OS_IDENTITY_API_VERSION must be set to 3.

EXAMPLES

Show the detailed information for server appweb01:

openstack \
    --os-project-name ExampleCo \
    --os-username demo --os-password secrete \
    --os-auth-url http://localhost:5000:/v2.0 \
    server show appweb01

The same command if the auth environment variables (OS_AUTH_URL, OS_PROJECT_NAME, OS_USERNAME, OS_PASSWORD) are set:

openstack server show appweb01

Create a new image:

openstack image create \
    --disk-format=qcow2 \
    --container-format=bare \
    --public \
    --copy-from http://somewhere.net/foo.img \
    foo

FILES

~/.openstack

Placeholder for future local state directory. This directory is intended to be shared among multiple OpenStack-related applications; contents are namespaced with an identifier for the app that owns it. Shared contents (such as ~/.openstack/cache) have no prefix and the contents must be portable.

ENVIRONMENT VARIABLES

The following environment variables can be set to alter the behaviour of openstack. Most of them have corresponding command-line options that take precedence if set.

OS_AUTH_URL

Authentication URL

OS_DOMAIN_NAME

Domain-level authorization scope (name or ID)

OS_PROJECT_NAME

Project-level authentication scope (name or ID)

OS_PROJECT_DOMAIN_NAME

Domain name or id containing project

OS_USERNAME

Authentication username

OS_PASSWORD

Authentication password

OS_USER_DOMAIN_NAME

Domain name or id containing user

OS_TRUST_ID

id of the trust to use as a trustee user

OS_DEFAULT_DOMAIN

Default domain ID (Default: 'default')

OS_REGION_NAME

Authentication region name

OS_CACERT

CA certificate bundle file

OS_IDENTITY_API_VERSION

Identity API version (Default: 2.0)

OS_XXXX_API_VERSION

Additional API version options will be available depending on the installed API libraries.
