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>]

Note

If a password is not provided above (in plaintext), you will be interactively prompted to provide one securely.

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>
