[Bug?] kubel-use-namespace-list auto doesn't work

[snowiow]

I'm not sure if this is really a bug or not, but if I execute the command from the code to determine if I'm able to list namespaces I get the following warning before the real answer:

 $ kubectl auth can-i list namespaces -n default
Warning: resource 'namespaces' is not namespace scoped
yes

Sadly I can't find anything online regarding this specific warning and if I'm the only one having this problem. But would it make sense to check if a line with yes exists instead of checking the whole output for equality? https://github.com/abrochard/kubel/blob/master/kubel.el#L703

If this change is welcome, I would like to try to implement a fix myself, since it's quite some time since I last contributed 😄

Hi @snowiow !
Yeah this was discussed in #38 and there's #44 currently open on the topic. It's currently unclear to me what is the best course of action because the can-i command cannot be trusted and there are so many possible edge cases here based on cluster configurations.
The current system is to have kubel-use-namespace-list default to a fairly conservative auto behavior such that we reduce the risk of kubel appearing completely broken for new users if they have an edge case. Meanwhile advanced users can explore with the on or off option.
If there is a better solution out there, I'm very interested.

ah thank you, didn't see the older issue and the PR. Sadly I also don't know of a better solution.
I'll go with (setq kubel-use-namespace-list 'on) for now 👍
