SNO

We can deploy SNO cluster development drivers given access to the release images. You will need a release that has support for SNO deployment.

1. Obtain access to the image with a release that supports SNO. If there is a pull secret, add the secret to your pull secret json file associated with your provider connection secret associated with the cloud or environment you plan to deploy.

login to https://console-openshift-console.apps.ci.xxx.com/ with your github id (you must be in openshift org) copy the oc login command with token and login from the terminal oc registry login --to=- to dump your pull secret, and append this to your general pull secret

2. Define the clusterimageset for the release image

apiVersion: hive.openshift.io/v1
kind: ClusterImageSet
metadata:
  name: sno-4.8.0-0-2021-03-23
spec:
  releaseImage: registry.ci.openshift.org/ocp/release:4.8.0-0.ci-2021-03-23-080923

3. Reference this clusterimageset in the clusterdeployment.yaml

spec:
  ...
  provisioning:
    imageSetRef:
      name: sno-4.8.0-0-2021-03-23
    installConfigSecretRef:
      name: sresnotest0-install-config
    sshPrivateKeySecretRef:
      name: sresnotest0-ssh-private-key
  pullSecretRef:
    name: sresnotest0-pull-secret

4. Make sure the install-config.yaml references a single master, and zero worker nodes
