RedHat Openshift Origin cluster on Azure

When creating the RedHat Openshift Origin cluster on Azure, you will need an SSH RSA key for access.

SSH Key Generation

1. Windows - https://www.digitalocean.com/community/tutorials/how-to-create-ssh-keys-with-putty-to-connect-to-a-vps
2. Linux - https://help.ubuntu.com/community/SSH/OpenSSH/Keys#Generating_RSA_Keys
3. Mac - https://help.github.com/articles/generating-ssh-keys/#platform-mac

Create the cluster

Create the cluster on the Azure Portal

Create the cluster with powershell

New-AzureRmResourceGroupDeployment -Name <DeploymentName> -ResourceGroupName <RessourceGroupName> -TemplateUri https://raw.githubusercontent.com/derdanu/azure-openshift/master/azuredeploy.json

Create the cluster with azure cli

azure group deployment create <RessourceGroupName> <DeploymentName> --template-uri https://raw.githubusercontent.com/derdanu/azure-openshift/master/azuredeploy.json

Install Openshift Origin with Ansible

After the Azure resources have been deployed by using this ARM template, you must connect via SSH to the jumbox. SSH Agentforwarding is required. The Installation is based on Openshift Ansible. The lastest repository has been checked out on the jumpbox into the directory /opt/openshift-ansible/ and a minimal configuration file was created at /etc/ansible/hosts for Openshift Origin. To start the installation call the following bash script:

Bash or Cygwin Terminal

user@localmachine:~$ eval $(ssh-agent)
user@localmachine:~$ ssh-add
user@localmachine:~$ ssh -A <JumpboxIP>
[adminUsername@jumpbox ~]$ ./openshift-install.sh

Putty on Windows

To login on the jumpbox please refer to the Agent forwarding HowTo for Putty using Pageant.

[adminUsername@jumpbox ~]$ ./openshift-install.sh
