Install RedHat OKD 3.10 on your development box.

This repository is a set of scripts that will allow you easily install the latest version (3.10) 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.

Installation

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/gshipley/installcentos.git

3. Execute the installation script

cd installcentos
./install-openshift.sh

Automation

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

Development

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

Testing

The script is tested using the included container and the validate.sh script. The SSH key passed to the container needs to be imported into DigitalOcean as installcentos or the SSH_KEY_NAME variable needs to be set.

make

docker run -ti -e DIGITALOCEAN_ACCESS_TOKEN="<TOKEN>" \
	-v <private key file path>:/root/.ssh/<private key file name> -v <private key file path>.pub:/root/.ssh/<private key file name>.pub \
