Guest clustering for OpenShift.
- Admin access to an OpenShift cluster.
- The OpenShift
ocCLI tool. - Kustomize
Install HyperShift into the management cluster:
$ make installRemove HyperShift from the management cluster:
$ make uninstallCreate a new guest cluster by creating an OpenShiftCluster resource. For now,
the cluster will be based on the version of the management cluster itself.
Here's an example:
apiVersion: hypershift.openshift.io/v1alpha1
kind: OpenShiftCluster
metadata:
name: guest-hello
spec:
baseDomain: guest-hello.devcluster.openshift.com
pullSecret: '{"auths": { ... }}'
serviceCIDR: 172.31.0.0/16
podCIDR: 10.132.0.0/14
sshKey: 'ssh-rsa ...'
initialComputeReplicas: 1Get the guest cluster's kubeconfig using:
$ oc get secret --namespace guest-hello admin-kubeconfig --template={{.data.kubeconfig}} | base64 -DYou can 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.largeAnd delete the cluster using:
$ oc delete --namespace hypershift openshiftclusters/guest-hello
