Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

---
- name: Upgrade nodes
  hosts: oo_nodes_to_upgrade
  serial: 1
  any_errors_fatal: true

  pre_tasks:
  - name: Mark unschedulable
    command: >
      {{ hostvars[groups.oo_first_master.0].openshift.common.client_binary }} adm manage-node {{ openshift.node.nodename | lower }} --schedulable=false
    delegate_to: "{{ groups.oo_first_master.0 }}"

  - name: Drain Node for Kubelet upgrade
    command: >
      {{ hostvars[groups.oo_first_master.0].openshift.common.admin_binary }} drain {{ openshift.node.nodename | lower }} --force --delete-local-data --ignore-daemonsets
    delegate_to: "{{ groups.oo_first_master.0 }}"
    register: l_docker_upgrade_drain_result
    until: not l_docker_upgrade_drain_result | failed
    retries: 60
    delay: 60


  roles:
  - openshift_facts
  - docker
  - openshift_node_dnsmasq
  - openshift_node_upgrade

  post_tasks:
  - name: Set node schedulability
    command: >
      {{ hostvars[groups.oo_first_master.0].openshift.common.client_binary }} adm manage-node {{ openshift.node.nodename | lower }} --schedulable=true
    delegate_to: "{{ groups.oo_first_master.0 }}"
