OpenShift 3.11 on CentOS 7

I had a friend who was having some issues with installing OpenShift 3.11 on a single node so I took to documenting my steps taken for my test deployment. We will assume you have installed the latest version of CentOS on your node that you will be deploying on.

From there you will want to log in and update the system.

sudo yum update -y

Next we will install the dependencies we need to continue followed by a reboot.

sudo yum install -y epel-release && sudo yum install -y python-pip python-devel git && sudo yum group install -y "Development Tools" && sudo reboot

Now that we have our dependencies installed and our system up to date we will want to clone the openshift-ansible install from github.

git clone https://github.com/openshift/openshift-ansible
cd openshift-ansible
git checkout release-3.11

Now we will install the python dependencies using pip we installed earlier.

sudo pip install -r requirements.txt

Finally we run the two playbooks needed to deploy the standalone 3.11 version of OpenShift on CentOS 7.

sudo ansible-playbook -i inventory/hosts.localhost playbooks/prerequisites.yml
sudo ansible-playbook -i inventory/hosts.localhost playbooks/deploy_cluster.yml

Enjoy your OpenShift 3.11 test environment!
