#186 broke k0sctl kubeconfig

[rgl]

I had to revert #186 to be able to use k0sctl kubeconfig (it hangs and never returns anything).

Can you please verify what is going on?

Using 658cd39 (which is v0.10.0-beta.2) and reverting #186 works fine here.

I'm using this with k0s v1.21.3+k0s.0.

Odd, I don't see how it could break kubeconfig as it doesn't use the spec.api.port for anything but to replace the port number in the api url. I updated #182 to use main to verify.

Now it seems to give level=fatal msg="PANIC: interface conversion: interface {} is nil, not int"

Fixed that panic with a typecheck, and the tests pass fine. I don't see where it could hang. Can you get any clue from --debug where it's blocking?

Here's the --debug output with 658cd39:

BTW, it would be nice that the logging would be written to stderr, that way we could always use --debug while redirect stdout to the kubeconfig file.

I will try with the latest revision.

The debug log always goes to the cache dir (~/.k0sctl/cache/k0sctl.log or /var/cache/k0sctl/k0sctl.log) even if you don't use --debug.

The panic is what I fixed in the beta.3. You mentioned that something froze forever?

[rgl]

nice to known about the k0sctl.log files!

590faf6 (aka beta.3) fixed the problem I was having! :-)

for some reason, k0sctl kubeconfig --config /vagrant/shared/k0sctl.yaml seemed to never return to the prompt. but whatever it was, now worked :-)

Thank you!
