Description

This Puppet module manages Ansible for setting up an OpenShift cluster with the official openshift-ansible Playbooks.

Setup

What openshift affects

The module has two "roles":

• openshift::role::ansible_master:
  • Installs Ansible
  • Checks out openshift-ansible from git
  • Configures SSH for Ansible
  • Writes the inventory file in YAML format
• openshift::role::node:
  • Installs required packages
  • Enables NetworkManager
  • Add some missing CA certificates

Setup Requirements

Required modules:

• vcsrepo
• inifile

Beginning with openshift

On the host you want to run Ansible, apply the ansible_master role and pass the inventory to it:

class { 'openshift::role::ansible_master':
  host_groups => {
    'OSEv3' => {
      children => ["nodes", "masters"],
    },
    masters => {
      vars => {
        osm_default_node_selector => "foo=bar",
      },
      hosts => {
        "master1.example.com" => {},
        "master2.example.com" => {},
      },
      children => ["etcd"],
    },
    nodes => {
      hosts => {
        "node[1:9].example.com" => {
          custom_var => true,
        },
      },
    },
  }
}

This parameters can also be configured in Hiera.

An all nodes, apply the node role:

class { 'openshift::role::node': }
