vi /HOME/OcpMulticlusterV1/ClusterA/main.tf
vi /HOME/OcpMulticlusterV1/ClusterA/terraform.tfvars
vi /HOME/OcpMulticlusterV1/ClusterA/variables.tf
  • Deploy with Terraform.
cd $HOME/OcpMulticlusterV1/ClusterB/clusters/4.11

terraform apply
  1. Install Openshift
cd $HOME/OcpMulticlusterV1/ClusterB/openshift

  1. From another terminal Check installation process
cd $HOME/OcpMulticlusterV1/ClusterB
oc --kubeconfig openshift/auth/kubeconfig get csr
oc --kubeconfig openshift/auth/kubeconfig get csr -ojson | jq -r '.items[] | select(.status == {} ) | .metadata.name' | xargs oc --kubeconfig openshift/auth/kubeconfig adm certificate approve
oc --kubeconfig openshift/auth/kubeconfig get nodes
oc --kubeconfig openshift/auth/kubeconfig get co
  1. During installation approve the csr
cd $HOME/OcpMulticlusterV1/ClusterB
oc --kubeconfig openshift/auth/kubeconfig get csr
oc --kubeconfig openshift/auth/kubeconfig get csr -o json | jq -r '.items[] | select(.status == {} ) | .metadata.name' | xargs oc --kubeconfig openshift/auth/kubeconfig adm certificate approve
