Hypershift POC

All the following assumes KUBECONFIG points to the management cluster.

Build binaries:

$ make

Install the operator's supporting resources into the management cluster:

$ oc apply --filename manifests/

Define release image info to be referenced by clusters:

hack/generate-release-images.rb | oc apply --filename -

Run the operator:

$ bin/hypershift-operator run --control-plane-operator-image quay.io/hypershift/hypershift:latest

Run the sigs.k8s.io cluster API controller:

$ git clone -b set-providerID [email protected]:enxebre/cluster-api.git
$ cd cluster-api && make manager-core
$ ./bin/manager

Export your AWS to environment variables and run the sigs.k8s.io cluster API AWS controller:

$ cd ~/go/src/sigs.k8s.io/
$ git clone -b decouple-machine-infra [email protected]:enxebre/cluster-api-provider-aws-2.git cluster-api-provider-aws
cd cluster-api-provider-aws && make manager-aws-infrastructure
./bin/manager --alsologtostderr --metrics-addr=0 --health-addr=0

Create a cluster, referencing a release image present in the release-images configmap previously created:

apiVersion: hypershift.openshift.io/v1alpha1
kind: OpenShiftCluster
metadata:
  namespace: hypershift
  name: guest-hello
spec:
  releaseImage: quay.io/openshift-release-dev/ocp-release@sha256:d78292e9730dd387ff6198197c8b0598da340be7678e8e1e4810b557a926c2b9
  baseDomain: guest-hello.devcluster.openshift.com
  pullSecret: '{"auths": { ... }}'
  serviceCIDR: 172.31.0.0/16
  podCIDR: 10.132.0.0/14
  sshKey: 'ssh-rsa ...'
  initialComputeReplicas: 1

Create additional nodePools

apiVersion: hypershift.openshift.io/v1alpha1
kind: NodePool
metadata:
  name: guest-hello-custom-nodepool
  namespace: hypershift
spec:
  clusterName: guest-hello
  autoScaling:
    max: 0
    min: 0
  nodeCount: 1
  platform:
    aws:
      instanceType: m5.large

Get the cluster kubeconfig using:

$ oc get secret --namespace hypershift guest-hello-kubeconfig --template={{.data.value}} | base64 -D

And delete the cluster using:

$ oc delete --namespace hypershift openshiftclusters/guest-hello
