OpenShift on VMware

Demo videos:

1. Install OpenShift 4.6.1 via UPI on VMware https://youtu.be/6TvyHBdHhes
2. OCP VMware Internal Registry Setup https://youtu.be/_60RLgkHVMw
3. Chrony NTP on OpenShift https://youtu.be/_60RLgkHVMw

Access the downloads from https://cloud.redhat.com See the documentation at https://docs.openshift.com/container-platform/4.6/installing/installing_vsphere/installing-vsphere.html

1. Create your own install-config.yaml based off the template contained herein
   vi install-config.yaml

2. Create a configuration directory and transfer your install-config.yaml there
   mkdir -p INSTALL ; mv install-config.yaml INSTALL

3. Create your manifests
   openshift-install create manifests --dir=INSTALL

4. Backup the worker node machineset
   mv INSTALL/openshift/99_openshift-cluster-api_worker-machineset-0.yaml .

5. Remove the node manifests since we'll be building them manually
   rm -f INSTALL/openshift/99_openshift-cluster-api_master-machines-*.yaml INSTALL/openshift/99_openshift-cluster-api_worker-machineset-*.yaml

6. Set mastersSchedulable to false
   sed -i -e 's/true/false/g' INSTALL/manifests/cluster-scheduler-02-config.yml

7. Adding Windows Nodes (optional)

   1. Copy the network config to a new manifest
      cp manifests/cluster-network-02-config.yml manifests/cluster-network-03-config.yml
   2. Update the apiVersion & spec to support HNS

      apiVersion: operator.openshift.io/v1
      ...
      ...
      spec​:​
        defaultNetwork:    
          type: OVNKubernetes
          ovnKubernetesConfig:
            hybridOverlayConfig:
              hybridClusterNetwork:
              - cidr: 10.132.0.0/14
                hostPrefix: 23
      

8. Create ignition files
   openshift-install create ignition-configs --dir=INSTALL

9. Encode the master and worker ignition files
   base64 -i INSTALL/master.ign -o INSTALL/master.64 ; base64 -i INSTALL/worker.ign -o INSTALL/worker.64

10. Copy your bootstrap.ign file to your webserver... (you're on your own here)
    scp INSTALL/bootstrap.ign $server:/path/to/www tip: Ensure you have global read permissons on that file (chmod +r bootsrap.ign)

11. Create a boot-append.ign file and encode it

    {
    "ignition": {
        "config": {
        "merge": [
            {
            "source": "http://$server/path/to/bootstrap.ign" 
            }
        ]
        },
        "version": "3.1.0"
      }
    }
    

    base64 -i boot-append.ign -o boot-append.64

Your setup is now done, from here on out I would recommend viewing the demo video since we'll be using VMware vCenter.
