OpenStackClient

OpenStackClient (OSC) is a command-line client for OpenStack that brings the command set for Compute, Identity, Image, Network, Object Store and Block Storage APIs together in a single shell with a uniform command structure. Support for additional service APIs is provided via plugins.

The primary goal is to provide a unified shell command structure and a common language to describe operations in OpenStack.

Getting Started

OpenStack Client can be installed from PyPI using pip:

python3 -m pip install python-openstackclient

You can use --help or the help command to get a list of global options and supported commands:

openstack --help
openstack help

You can also get help for a specific command:

openstack server create --help
openstack help server create

You can add support for additional services by installing their clients. For example, to add support for the DNS service (designate):

python3 -m pip install python3-designateclient

A Dockerfile is provided for your convenience in the repository. You can use this to build your own container images:

git clone https://opendev.org/openstack/python-openstackclient
cd python-openstackclient
podman build . -t example.com/myuser/openstackclient

For more information the available options and commands, refer to the Users Guide.

Configuration

OpenStack Client must be configured with authentication information in order to communicate with a given OpenStack cloud. This configuration can be achieved via a clouds.yaml file, a set of environment variables (often shared via an openrc file), a set of command-line options, or a combination of all three. Your cloud provider or deployment tooling will typically provide either a clouds.yaml file or openrc file for you. If using a clouds.yaml file, OpenStack Client expects to find it in one of the following locations:

If set, the path indicated by the OS_CLIENT_CONFIG_FILE environment variable
. (the current directory)
$HOME/.config/openstack
/etc/openstack

The options you should set will depend on the configuration of your cloud and the authentication mechanism(s) supported. For example, consider a cloud that supports username/password authentication. Configuration for this cloud using a clouds.yaml file would look like so:

clouds:
  my-cloud:
    auth:
      auth_url: '<url-to-openstack-identity>'
      project_name: '<project-name>'
      project_domain_name: '<project-domain-name>'
      username: '<username>'
      user_domain_name: '<user-domain-name>'
      password: '<password>'  # (optional)
    region_name: '<region>'

The corresponding environment variables would look very similar:

export OS_AUTH_URL=<url-to-openstack-identity>
export OS_REGION_NAME=<region>
export OS_PROJECT_NAME=<project-name>
export OS_PROJECT_DOMAIN_NAME=<project-domain-name>
export OS_USERNAME=<username>
export OS_USER_DOMAIN_NAME=<user-domain-name>
export OS_PASSWORD=<password>  # (optional)

Likewise, the corresponding command-line options would look very similar:

openstack
--os-auth-url <url-to-openstack-identity>
--os-region <region>
--os-project-name <project-name>
--os-project-domain-name <project-domain-name>
--os-username <username>
--os-user-domain-name <user-domain-name>
[--os-password <password>]

Some clouds use federated authentication. If this is the case, your configuration will be slightly more involved. For example, to configure username/password authentication for a federated user using a clouds.yaml file:

clouds:
  my-cloud:
    auth:
      auth_url: '<url-to-openstack-identity>'
      project_name: '<project-name>'
      project_domain_name: '<project-domain-name>'
      username: '<username-in-idp>'
      user_domain_name: '<user-domain-name>'
      password: '<password-in-idp>'
      identity_provider: '<the-desired-idp-in-keystone>'
      client_id: '<the-client-id-configured-in-the-idp>'
      client_secret: '<the-client-secret-configured-in-the-idp>'
      openid_scope: '<the-scopes-of-desired-attributes-to-claim-from-idp>'
      protocol: '<the-protocol-used-in-the-apache2-oidc-proxy>'
      access_token_type: '<the-access-token-type-used-by-your-idp>'
      discovery_endpoint: '<the-well-known-endpoint-of-the-idp>'
    auth_type: 'v3oidcpassword'
    region_name: '<region>'

The corresponding environment variables would look very similar:

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_TYPE=v3oidcpassword
export OS_USERNAME=<username-in-idp>
export OS_PASSWORD=<password-in-idp>
export OS_IDENTITY_PROVIDER=<the-desired-idp-in-keystone>
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>

Likewise, the corresponding command-line options would look very similar:

--os-project-name <project-name>
--os-project-domain-name <project-domain-name>
--os-auth-url <url-to-openstack-identity>
--os-identity-api-version 3
--os-auth-plugin openid
--os-auth-type v3oidcpassword
--os-username <username-in-idp>
--os-password <password-in-idp>
--os-identity-provider <the-desired-idp-in-keystone>
--os-client-id <the-client-id-configured-in-the-idp>
--os-client-secret <the-client-secred-configured-in-the-idp>
--os-openid-scope <the-scopes-of-desired-attributes-to-claim-from-idp>
--os-protocol <the-protocol-used-in-the-apache2-oidc-proxy>
--os-access-token-type <the-access-token-type-used-by-your-idp>
--os-discovery-endpoint <the-well-known-endpoint-of-the-idp>
