OpenShift KVM Lab

This repository is used to get an OpenShift lab running quickly on a linux machine with enough horsepower to support a small 4 node cluster via Ansible. My laptop has 32GB of RAM and that is sufficient to run this with the defaults.

Your machine must have passwordless sudo rights.

Install Prerequisites

sudo dnf -y install @virtualization python3-pip
sudo pip3 install ansible==2.6.11
sudo mkdir /usr/share/ansible
cd /usr/share/ansible
sudo git clone https://github.com/openshift/openshift-ansible.git
cd openshift-ansible
sudo git checkout release-3.11

Deploying the Cluster

Set RHSM credentials

export RHSM_USERNAME=
export RHSM_PASSWORD=
export RHSM_POOL=

Run deployment playbook

[user@host openshift-kvm-lab]$ ./playbooks/deploy.yml | tee deploy.log

Tearing it all down

[user@host openshift-kvm-lab]$ ./playbooks/teardown.yml -e '@vars/infrastructure.yml'
