Please note that this terraform script is designed to used only with-in CloudShell on your Oracle Cloud Account. And make sure that you have enough privileges to create resources or manage tenancy before executing this script. You should have your own Domain and Point to the Name Servers provided at the end of the Terraform script executiom
This installer designed to work with https://console.redhat.com/openshift assisted cluster installation method. And you will have to terminate and re-create nodes with preserved boot volumes per each node manually.
- Clone/Download this repository to your CloudShell
- Generate OpenSSH key pairs using ssh-keygen if you do not have it already on your CloudShell environment
- Go to Assisted Cluster Creation Wizard on RedHat OpenShift Conole and copy live ISO download command after providing your ssh public key
- Edit terraform.tfvars file with your tenancy information
- Execute terraform apply command and wait until process completed and your Instances shows up on RedHat OpenShift console (See video at bottom of this page)
- When all shows up, continue the cluster creation as demonstrated on the video
- RedHat OpenShift Console will show amber color warning when Instances got boot back to the live ISO (Expected Situation). Then Terminate specific instance while preserving its boot volume (Do not use terraform to destroy)
- Re create instance manually using preserved boot volume on OpenShift VCN -> Cluster Subnet with having Same IP Address for the new Instance.
- Please note that the OpenShift Console will take upto 5-10 mins to show up instance upon creation. So have some patience on the process (This is the reason for having multiple pauses on bottom demo video)
- Please make sure to download kubeconfig file from OpenShift Assisted Cluster Installation page and it will be available to download from the console for 20 days.
Please note that this is a Proof of Concept for running OpenShift on Oracle Cloud Infrastructure. Please review security using provided tools on Oracle Cloud to ensure that your installation is fully secured against known threats before going to production
Please make sure to Terminate or Power Off the instance used to create iPXE environment. Instance Name -> iPXE Web Server.
