community.okd.openshift_auth module – Authenticate to OpenShift clusters which require an explicit login step

Note

This module is part of the community.okd collection (version 2.2.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.okd. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.okd.openshift_auth.

New in community.okd 0.2.0

Synopsis

• This module handles authenticating to OpenShift clusters requiring explicit authentication procedures, meaning ones where a client logs in (obtains an authentication token), performs API operations using said token and then logs out (revokes the token).

• On the other hand a popular configuration for username+password authentication is one utilizing HTTP Basic Auth, which does not involve any additional login/logout steps (instead login credentials can be attached to each and every API call performed) and as such is handled directly by the k8s module (and other resource–specific modules) by utilizing the host, username and password parameters. Please consult your preferred module’s documentation for more details.

Requirements

The below requirements are needed on the host that executes this module.

• python >= 3.6

• urllib3

• requests

• requests-oauthlib

Parameters

Parameter	Comments
api_key string	When state is set to absent, this specifies the token to revoke.
ca_cert aliases: ssl_ca_cert path	Path to a CA certificate file used to verify connection to the API server. The full certificate chain must be provided to avoid certificate validation errors.
host string / required	Provide a URL for accessing the API server.
password string	Provide a password for authenticating with the API server.
state string	If set to present connect to the API server using the URL specified in host and attempt to log in. If set to absent attempt to log out by revoking the authentication token specified in api_key. Choices: "present" ← (default) "absent"
username string	Provide a username for authenticating with the API server.
validate_certs aliases: verify_ssl boolean	Whether or not to verify the API server’s SSL certificates. Choices: false true ← (default)

Examples

- hosts: localhost
  module_defaults:
    group/k8s:
      host: https://k8s.example.com/
      ca_cert: ca.pem
  tasks:
  - block:
    # It's good practice to store login credentials in a secure vault and not
    # directly in playbooks.
    - include_vars: openshift_passwords.yml

    - name: Log in (obtain access token)
      community.okd.openshift_auth:
        username: admin
        password: "{{ openshift_admin_password }}"
      register: openshift_auth_results

    # Previous task provides the token/api_key, while all other parameters
    # are taken from module_defaults
    - name: Get a list of all pods from any namespace
      kubernetes.core.k8s_info:
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
        kind: Pod
      register: pod_list

    always:
    - name: If login succeeded, try to log out (revoke access token)
      when: openshift_auth_results.openshift_auth.api_key is defined
      community.okd.openshift_auth:
        state: absent
        api_key: "{{ openshift_auth_results.openshift_auth.api_key }}"
