RE: Connecting two kubernetes clusters through submariner

[Vaishnavi Rajulu]

Hi,

I am using two kubernetes clusters one is RKE2 and another one is K3S.

I have deployed broker in RKE2. Now when I try to join the broker from K3S, I get this error.

master:~/.kube# subctl join --kubeconfig config broker-info.subm
 ✓ broker-info.subm indicates broker is at https://x.x.x.x:6443
 ✗ Error building the cluster.Info for the default configuration: error retrieving Submariner: failed to get API group resources: unable to retrieve the complete list of server APIs: submariner.io/v1alpha1: Unauthorized

Thanks for reaching out Vaishnavi,

Subctl commands that need access to Kubernetes cluster handle the same access mechanisms as kubectl (see kubectl options), in case of kubeconfig file with multiple contexts a specific context can be chosen using the --context option; By default,subctl commands use the chosen kubeconfig's curent context.

In your case, it seems that current context in kubeconfig you provided is unauthorized to access  submariner.io/v1alpha1 , could you specify a different context?

Hello Vaishnavi,

Thanks for your interest in Submariner!

There are known issues with K3s.

Unfortunately, we haven't been able to find devs with access to K3s clusters and/or cycles to support it.

We've removed the K3s quickstart to try to avoid misleading people.

As always, we'd welcome contributions.

Thanks,

Daniel

Hi all,

I filed this GH issue to track subctl unauthorized error. 

subctl join must be run as a user with appropriate permissions,

It should be documented in Submariner web site.
