OpenShift Enterprise 3 Vagrant Setup

This project contains a Vagrant file creating multiple VMs for running and demoing OpenShift Enterprise v3. The demo environment consists of one VM running dnsmasq as the DNS server, one OpenShift master, and two OpenShift nodes.

Architecture

The demo environment setup contains the following VMs:

• ose3-master.example.com - This is the OpenShift Master
• ose3-node[1|2].example.com - These are the nodes supporting the system.
• ose3-dns.example.com - The dnsmasq server with a wildcard DNS entry for cloudapps.example.com

Preparation

In order to use this you need to get a base VM setup. In order to do this, first create a Red Hat Enterprise Linux v7.1 VM. After it has been installed and registered, you will need to perform some basic set up tasks.

You can refer to the directions below or follow the instructions in the documentation from section 1.2.4.

First disable all repositories, then enable only the ones needed for OSEv3.

subscription-manager repos --disable="*"
subscription-manager repos \
    --enable="rhel-7-server-rpms" \
    --enable="rhel-7-server-extras-rpms" \
    --enable="rhel-7-server-optional-rpms" \
    --enable="rhel-7-server-ose-3.0-rpms"

Make sure that deltarpm is there to make updating easier.

yum install -y deltarpm

Next remove NetworkManager to keep it from messing with the network connection at random times.

yum remove -y NetworkManager*

Install some useful tools.

yum install -y wget git net-tools bind-utils iptables-services bridge-utils

Then update the system.

yum update -y

Then you will need to install Docker, make some configuration changes then enable and start it.

yum install -y docker
sed -i -e "s/^OPTIONS=.*/OPTIONS='--insecure-registry=0.0.0.0/0 --selinux-enabled=true'"
systemctl enable docker; systemctl start docker

Once this is complete, you will need to package the Vagrant box and import it into Vagrant. Please refer to the Vagrant documentation to do this for your hypervisor.

Running the system

Make sure that you update the submodules with:

git submodule init
git submodule update

After that, you can just run vagrant up.

Enjoy.
