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.
AUTHENTICATION METHODS¶
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)
openstack can use different types of authentication plugins provided by the keystoneclient library. The following default plugins are available:
token
: Authentication with a tokenpassword
: Authentication with a username and a passwordopenid
: Authentication using the protocol OpenID Connect
Refer to the keystoneclient library documentation for more details about these plugins and their options, and for a complete list of available plugins. Please bear in mind that some plugins might not support all of the functionalities of openstack; for example the v3unscopedsaml plugin can deliver only unscoped tokens, some commands might not be available through this authentication method.
Additionally, it is possible to use Keystone’s service token to authenticate, by setting the options --os-token
and --os-url
(or the environment variables OS_TOKEN
and OS_URL
respectively). This method takes precedence over authentication plugins.
Note
To use the v3unscopedsaml
method, the lxml package will need to be installed.
AUTHENTICATION USING FEDERATION¶
To use federated authentication, your configuration file needs the following:
export OS_PROJECT_NAME=<project-name>
export OS_PROJECT_DOMAIN_NAME=<project-domain-name>
export OS_AUTH_URL=<url-to-openstack-identity>
export OS_IDENTITY_API_VERSION=3
export OS_AUTH_PLUGIN=openid
export OS_AUTH_TYPE=v3oidcpassword
export OS_USERNAME=<username-in-idp>
export OS_PASSWORD=<password-in-idp>
export OS_IDENTITY_PROVIDER=<the-desired-idp>
export OS_CLIENT_ID=<the-client-id-configured-in-the-idp>
export OS_CLIENT_SECRET=<the-client-secred-configured-in-the-idp>
export OS_OPENID_SCOPE=<the-scopes-of-desired-attributes-to-claim-from-idp>
export OS_PROTOCOL=<the-protocol-used-in-the-apache2-oidc-proxy>
export OS_ACCESS_TOKEN_TYPE=<the-access-token-type-used-by-your-idp>
export OS_DISCOVERY_ENDPOINT=<the-well-known-endpoint-of-the-idp>
export OS_ACCESS_TOKEN_ENDPOINT=<the-idp-access-token-url>
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 options:
- --os-cloud <cloud-name>¶
openstack will look for a
clouds.yaml
file that contains a cloud configuration to use for authentication. See CLOUD CONFIGURATION below for more information.
- --os-auth-type <auth-type>¶
The authentication plugin type to use when connecting to the Identity service.
If this option is not set, openstack will attempt to guess the authentication method to use based on the other options.
If this option is set, its version must match
--os-identity-api-version
- --os-auth-url <auth-url>¶
Authentication URL
- --os-url <service-url>¶
Service URL, when using a service token for authentication
- --os-domain-name <auth-domain-name>¶
Domain-level authorization scope (by name)
- --os-domain-id <auth-domain-id>¶
Domain-level authorization scope (by ID)
- --os-project-name <auth-project-name>¶
Project-level authentication scope (by name)
- --os-project-id <auth-project-id>¶
Project-level authentication scope (by ID)
- --os-project-domain-name <auth-project-domain-name>¶
Domain name containing project
- --os-project-domain-id <auth-project-domain-id>¶
Domain ID containing project
- --os-username <auth-username>¶
Authentication username
- --os-password <auth-password>¶
Authentication password
- --os-token <token>¶
Authenticated token or service token
- --os-user-domain-name <auth-user-domain-name>¶
Domain name containing user
- --os-user-domain-id <auth-user-domain-id>¶
Domain ID containing user

Note
If you switch to openstackclient from project specified clients, like: novaclient, neutronclient and so on, please use –os-interface instead of –os-endpoint-type.
- --os-profile <hmac-key>¶

This key should be the value of one of the HMAC keys defined in the configuration files of OpenStack services to be traced.
- --os-beta-command¶

Suppress output except warnings and errors
- --debug¶
Show tracebacks on errors and set verbosity to debug
- --help¶

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 Block Storage 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.
CLOUD CONFIGURATION¶
Working with multiple clouds can be simplified by keeping the configuration
information for those clouds in a local file. openstack supports
using a clouds.yaml
configuration file.
Config Files¶
openstack will look for a file called clouds.yaml in the following locations:
Current Directory
~/.config/openstack
/etc/openstack
The first file found wins.
The keys match the openstack global options but without the
--os-
prefix:
clouds:
devstack:
auth:
auth_url: http://192.168.122.10:5000/
project_name: demo
username: demo
password: 0penstack
region_name: RegionOne
ds-admin:
auth:
auth_url: http://192.168.122.10:5000/
project_name: admin
username: admin
password: 0penstack
region_name: RegionOne
infra:
cloud: rackspace
auth:
project_id: 275610
username: openstack
password: xyzpdq!lazydog
region_name: DFW,ORD,IAD
In the above example, the auth_url
for the rackspace
cloud is taken
from clouds-public.yaml
:
public-clouds:
rackspace:
auth:
auth_url: 'https://identity.api.rackspacecloud.com/v2.0/'
Authentication Settings¶
OpenStackClient uses the Keystone authentication plugins so the required
auth settings are not always known until the authentication type is
selected. openstack will attempt to detect a couple of common
auth types based on the arguments passed in or found in the configuration
file, but if those are incomplete it may be impossible to know which
auth type is intended. The --os-auth-type
option can always be
used to force a specific type.
When --os-token
and --os-url
are both present the
token_endpoint
auth type is selected automatically. If
--os-auth-url
and --os-username
are present password
auth type is selected.
Logging Settings¶
openstack can record the operation history by logging settings in configuration file. Recording the user operation, it can identify the change of the resource and it becomes useful information for troubleshooting.
See Configuration about Logging Settings for more details.
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
.

FILES¶
~/.config/openstack/clouds.yaml
Configuration file used by the
--os-cloud
global option.~/.config/openstack/clouds-public.yaml
Configuration file containing public cloud provider information such as authentication URLs and service definitions. The contents of this file should be public and sharable.
clouds.yaml
may contain references to clouds defined here as shortcuts.~/.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.
