Set cluster name and number of control plane nodes from cluster configuration file for the "ocne cluster template" command. #51

Closed prasad-shirodkar closed 2 weeks ago

prasad-shirodkar commented 2 weeks ago

Example cluster configuration file: capi.yaml

provider: oci
name: pras-cluster
workerNodes: 3
controlPlaneNodes: 3
clusterDefinition: mycluster.oci
.....
.....

Create a new ClusterAPI yaml using

ocne cluster template -c capi.yaml > mycluster.oci

Cluster name correctly set to "pras-cluster" instead of "ocne". Other references to "ocne" that correctly updated as well.

$ grep --context=10 clusterName mycluster.oci

            provider-id: oci://{{ ds["id"] }}
