This repository is used to showcase the capabilities of the Agent-Based Installation for OpenShift 4.
In this repo, you will find the essential files needed to deploy a fully operational OpenShift 4 cluster in the various topologies. You can find:
sno: a Single Node OpenShift installation;compact: a three-node OpenShift installation where the control-plane will host the applications' workloads;ha: a fully HA OpenShift cluster with three control-plane nodes and two+ worker nodes.
Every topology comes with two variants:
connected: the cluster will access the internet to pull the images;disconnected: the cluster will access a private registry to pull the images.
To generate the ISO:
- go to the OpenShift flavor of choice:
cd <topology>/<variant>; - edit the manifests to match your environment;
- hint: make a backup copy of the manifests as they will be consumed in the next step!
- generate the ISO using the command:
openshift-install --dir . agent create image; - boot the generated ISO on the server(s) that are part of the cluster.
In addition, you will also find the scale-out-nodes directory, where you will find the instructions to add more worker nodes to your cluster.
