Install RedHat OKD 3.11 on your own server. For a local only install, it is suggested that you use CDK or MiniShift instead of this repo. This install method is targeted for a single node cluster that has a long life.

This repository is a set of scripts that will allow you easily install the latest version (3.11) of OKD in a single node fashion. What that means is that all of the services required for OKD to function (master, node, etcd, etc.) will all be installed on a single host. The script supports a custom hostname which you can provide using the interactive mode.

Please do use a clean CentOS system, the script installs all necesary tools and packages including Ansible, container runtime, etc.

1. Create a VM as explained in https://www.youtube.com/watch?v=ZkFIozGY0IA (this video) by Grant Shipley

2. Clone this repo

git clone https://github.com/csageder/installcentos.git

3. Execute the installation script

cd installcentos
./install-openshift.sh

1. Define mandatory variables for the installation process

# Domain name to access the cluster
$ export DOMAIN=<public ip address>.nip.io

# User created after installation
$ export USERNAME=<current user name>

# Password for the user
$ export PASSWORD=password

2. Define optional variables for the installation process

# Instead of using loopback, setup DeviceMapper on this disk.
# !! All data on the disk will be wiped out !!
$ export DISK="/dev/sda"

3. Run the automagic installation script as root with the environment variable in place:

curl https://raw.githubusercontent.com/gshipley/installcentos/master/install-openshift.sh | INTERACTIVE=false /bin/bash

For development it's possible to switch the script repo

# Change location of source repository
$ export SCRIPT_REPO="https://raw.githubusercontent.com/gshipley/installcentos/master"
$ curl $SCRIPT_REPO/install-openshift.sh | /bin/bash

The script is tested using the tooling in the validate directory.

To use the tooling, it's required to create file validate/env.sh with the DigitalOcean API key

export DIGITALOCEAN_TOKEN=""

and then run start.sh to start the provisioning. Once the ssh is connected to the server, the script will atatch to the tmux session running Ansible installer.

docker run -ti -e DIGITALOCEAN_ACCESS_TOKEN=""
-v :/root/.ssh/ -v .pub:/root/.ssh/.pub
quay.io/osevg/installcentos-validate

To destroy the infrastructure, run the `stop.sh` script.
