openshift-host-prep

Small repo to include ansible files to prepare VM for OpenShift installation

• playbooks/base_packages.yaml
  Contains the base packages and other configurations required by the cluster or nodes

• playbooks/prepare_hosts.yaml
  Contains the main logic and instructions to prepare the nodes defined in inventory file

• playbooks/prepare_cluster.yaml
  Contains the instructions to prepare master server and required packages

• local_hosts_inventory.yaml This is the file where you configure your local VMs, where the openshift packages should be donwloaded and installed.

• templates/openshift_inventory_file.template
  This is the inventory file that will be used as template for /etc/ansible/hosts in the cluster server. This file will be created once prepare_cluster.yaml is executed.

How to run the scripts (from your local computer)

• Clone this repo to your local computer
  
• Start up your VMs
  
• Modify the file "local_hosts_inventory.yaml" and replace with your server's name
  
• Adjust file "templates/openshift_inventory_file.template" if you need to modify inventory file. The file provided was tested and is supposed to work.
• The following scripts must be executed:
  --- playbooks/prepare_hosts.yaml
  It will install and configure base packages
  --- playbooks/prepare_cluster.yaml
  Once base packages are installed, you may run this script to download and install cluster packages.
  File "/etc/ansible/hosts" will be created in the cluster server based on templates file (templates/openshift_inventory_file.template).

Once this is done. You can move forward deploying openshift by running prerequisites and deploy files, from inside your Cluster Server.
