Let's check config.yml for installation using ansible.

OpenShift

when we install OpenShift, we will use config.yml file .

https://docs.openshift.org/latest/install_config/install/advanced_install.html#running-the-advanced-installation

~/openshift-ansible/playbooks/byo/config.yml

open openshift-ansible/playbooks/byo/config.yml

[root@centos01 ~]# cat openshift-ansible/playbooks/byo/config.yml
---
- include: openshift-cluster/config.yml
[root@centos01 ~]#

Next check “openshift-ansible/playbooks/byo/openshift-cluster/config.yml”.

open openshift-ansible/playbooks/byo/openshift-cluster/config.yml

github.com

  tasks:
  - include_vars: ../../byo/openshift-cluster/cluster_hosts.yml
  - add_host:
      name: "{{ item }}"
      groups: l_oo_all_hosts
    with_items: "{{ g_all_hosts | default([]) }}"
    changed_when: no

What is add_host task?

to be continued…

Let's check Advanced Installation of OpenShift origin.

OpenShift

check below page.
