Manage K3s cluster in TrueNAS SCALE 21.04 from Rancher

[headwhacker]

I have a K8s cluster and use Rancher to manage this cluster. I was able to add the K3s cluster created automatically by SCALE 21.04 in Rancher and appears as a seperate cluster (cool ).

So far Rancher see this system workloads in the SCALE cluster
coredns
openebs-zfs-controller
openebs-zfs-node
cattle-cluster-agent
fleet-agent

I tried to deploy a workload/app to the SCALE cluster using Rancher. I can see the workload started fine and logs look similar to the workload running on my K8s cluster. However, I can't find a way to access this workload so far from outside the cluster yet. Tried both nodeport and hostport for port mapping and even the node/host network namespace.

I know the Kubernetes implementation is still in early stage but just want to see how far it will take me as far as playing around the cluster. I look forward to the upcoming beta build improve on K8s support.

@headwhacker can you please share a debug of the system ( System Settings -> Advanced -> Save Debug ) and email me at waqar at the rate of ixsystems.com ?

@waqarahmed shouldn't connecting outside rancher connections to the k3sdaemon be blocked by the firewall currently?

@waqarahmed sent my debug to your email.

Rancher gives you a kubectl command to install a pod configure to report back over 443 and 443 access to truenas is allowed
