I'm using federation v2. I installed a federation control plane and join the host cluster into the federation. When I joined the second cluster with below code
kubefed2 join federated01 --cluster-context federated01 --host-cluster-context xxxx --add-to-registry --v=2I got
I0420 22:05:19.420250 24789 join.go:184] Failed to get joining cluster config: context "federated01" does not exist
F0420 22:05:19.420269 24789 join.go:133] Error: context "federated01" does not existHow to add joining cluster config? Can anyone help me?
I assume that you have to provide cluster, context and authentication details to federation control plane in order to join new member:
Furthermore, federation control plane requires credentials of the joined clusters to operate on them. These credentials are obtained from the local kubeconfig. kubefed join uses the cluster name specified as the argument to look for the cluster’s context in the local kubeconfig. If it fails to find a matching context, it exits with an error.
You might be able to check kubeconfig on the cluster you are willing to join with a command:
kubectl config view.
Next, you can manually inject sufficient cluster information into the host cluster kubeconfig:
kubectl config set-cluster
kubectl config set-context
kubectl config set-credentials
