NOTE: use ansible vaults or other security systems for storing credentials.

The following is an example playbook that makes use of the role to install keycloak from remote:

---
- hosts: ...
      collections:
        - middleware_automation.keycloak
      tasks:
        - name: Include keycloak role
          include_role:
            name: keycloak
          vars:
            keycloak_admin_password: "changeme"

The following is an example playbook that makes use of the role to install Red Hat Single Sign-On from RHN:

---
- name: Playbook for RHSSO
  hosts: keycloak
  collections:
    - middleware_automation.redhat_csp_download
  roles:
    - redhat_csp_download
  tasks:
    - name: Keycloak Role
      include_role:
        name: keycloak
      vars:
        keycloak_admin_password: "changeme"
        keycloak_rhsso_enable: True
        rhn_username: '<customer portal username>'
        rhn_password: '<customer portal password>'

The following example playbook makes use of the role to install keycloak from the controller node:

---
- hosts: ...
      collections:
        - middleware_automation.keycloak
      tasks:
        - name: Include keycloak role
          include_role:

          vars:
            keycloak_admin_password: "changeme"
            keycloak_offline_install: True
            # This should be the filename of keycloak archive on Ansible node: keycloak-16.1.0.zip

This playbook installs Red Hat Single Sign-On from an alternate url:

---
- hosts: keycloak
  collections:
    - middleware_automation.keycloak
  tasks:
    - name: Keycloak Role
      include_role:
        name: keycloak

        keycloak_admin_password: "changeme"
        keycloak_rhsso_enable: True
        keycloak_rhsso_download_url: "<REPLACE with download url>"
        # This should be the full of remote source rhsso zip file and can contain basic authentication credentials

The following is an example playbook that makes use of the role to install Red Hat Single Sign-On from the controller node:

---
- hosts: keycloak
