OpenShift Vagrant | 中文

☞ Notice

This project will be at maintainance stage and the OKD version support remains on RELEASE-3.11. It's been a while that openshift isn't a part of my work life and I have no time to maintain compatibility with the next openshift releases.

Any contributions are warmly welcomed at any time! I hope the project can make your life easy for a cup of coffee.

Overview

The OpenShift Vagrant project aims to make it easy to bring up a real OKD cluster by provisioning pre-configured Vagrantfile of several major releases of OKD on your local machine.

Prerequisites

• Host machine must have at least 8GB memory (16GB for OKD 3.11)
• Oracle VirtualBox installed on your host machine
• Vagrant (2.0 or above) installed on your host machine
• Vagrant plugin vagrant-hostmanager must be installed

OKD Version Support

Currently this project pre-configured and support the following major versions of the OKD:

• OKD v3.11 (default)
• OKD v3.10
• OKD v3.9
• OKD v3.7
• OKD v3.6

But, it's very easy to customize the respected ansible hosts file in order to support other incoming major versions.

The Vagrantfile uses Origin 3.11 and openshift-ansible release-3.11 branch by default. Feel free to adjust your versions by updating the following 2 variables in Vagrantfile:

1. OPENSHIFT_RELEASE
2. OPENSHIFT_ANSIBLE_BRANCH

The following table lists the corresponding version relationships between Origin and openshift-ansible:

OKD version	openshift-ansible branch
3.11.x	release-3.11
3.10.x	release-3.10
3.9.x	release-3.9
3.7.x	release-3.7
3.6.x	release-3.6

Getting Started

After adjusting your expected version information, now it's time to bring your cluster up and running.

This Vagrantfile will create 3 VMs in VirtualBox and the network base will be specified by variable NETWORK_BASE.

Checkout the table below for more details:

VM Node	Private IP	Roles
master	#{NETWORK_BASE}.101	node, master, etcd
node01	#{NETWORK_BASE}.102	node
node02	#{NETWORK_BASE}.103	node

Bring Vagrant Up

$ vagrant up

Provisioning Private Keys

$ vagrant provision --provision-with master-key,node01-key,node02-key

Install Origin Cluster Using Ansible

Run the following command if you would like to install origin previous to release-3.8:

$ vagrant ssh master -c 'ansible-playbook /home/vagrant/openshift-ansible/playbooks/byo/config.yml'

Run the following command for origin 3.8 or above:

vagrant ssh master \
        -c 'ansible-playbook /home/vagrant/openshift-ansible/playbooks/prerequisites.yml &&
            ansible-playbook /home/vagrant/openshift-ansible/playbooks/deploy_cluster.yml'

oc-up.sh

The above 3 steps have been grouped together as one script for you. To bring your cluster up, just use the following command:

$ ./oc-up.sh

Open Web Console

In browser of your host, open the following page: https://master.example.com:8443/ and you should see OpenShift Web Console login page. The default login account is admin/handhand

Have fun with OKD and Vagrant :p
