NAME
openstack - OpenStack Command Line Client
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 token
• password: Authentication with a username and a password
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.
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> | --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>

--os-password <auth-password>
Authentication password
--os-token <token>
Authenticated token or service token
--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>

--os-XXXX-api-version <XXXX-api-version>
Additional API version options will be available depending on the installed API
libraries.
--os-interface <interface>
Interface type. Valid options are public, admin and internal.
option --profile <hmac-key> HMAC key to use for encrypting context data for performance
profiling of requested operation. This key should be the value of one of the HMAC
keys defined in the configuration files of OpenStack services, user would like to
trace through.
--log-file <LOGFILE>
Specify a file to log output. Disabled by default.
-v, --verbose
Increase verbosity of output. Can be repeated.
-q, --quiet
suppress output except warnings and errors
--debug
show tracebacks on errors and set verbosity to debug
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 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://192.168.122.10:35357/
project_name: demo
username: demo
password: 0penstack
region_name: RegionOne
ds-admin:
auth:
auth_url: http://192.168.122.10:35357/
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.
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
