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 }}"
