How to acccess TrueNAS kubectl remotely from your local computer?

DISCLAIMER: This is an unofficial guide. If you mess things up then you may lock yourself out of TrueNAS or even worse, make it unusable. There's also no guarantee that this works in the future.

Through SSH

Currently the easiest way to access kubectl is through ssh and k3s tool. If you have ssh access enabled then you can ssh to your TrueNAS server and use it

Setup

First I created k3d cluster and installed our old istio there (1.6.11) using kubectl apply in sm-configuration dir. Also added couple of pods with sidecar enabled.

Before upgrade (background check)

Started recurring curl just to see if there's a disruption
