In this lab, we will verify the Ansible inventory file, so it fits our lab cluster. The Inventory file describes, how the cluster will be built.
Take a look at the prepared inventory file:
[ec2-user@master0 ~]$ less /etc/ansible/hosts
Download the default example hosts file from the OpenShift GitHub repository and compare it to the prepared inventory for the lab.
[ec2-user@master0 ~]$ wget https://raw.githubusercontent.com/openshift/openshift-ansible/release-3.6/inventory/byo/hosts.ose.example
[ec2-user@master0 ~]$ vimdiff hosts.ose.example /etc/ansible/hosts
