Add merge/import command about kubectx HOT 7 CLOSED

Oh cool didn't know that exist. I still think a shortcut method like kubectx import ./file1 would be more preferable (given that everything this util does exist anyways except shorter and more easy accessible)

from kubectx.

I just don't think it's a super common operation that people do out there. But if this comes up from other people, I'll be open to doing it. I'm trying to keep feature creep out and keep the tool focused.

What you're looking for is:

KUBECONFIG=file1:file2 kubectl config view --minify > ~/.kube/config

Hmm I just tested your solution and successful destroyed my kubeconfig file (thats on me). But unfortunately specifying multiple kubeconfig files in KUBECONFIG and using config view redacts certificate information which renders the result not usable.

This is my bad. :) I should've told you to use kubectl config view --merge --flatten. This preserves both cluster certficate-authority-data and user client-{certificate,key}-data fields. (see kubemci repo for example usages of this).

It would be a pretty useful thing to have as theres one specific use case which the above example doesn't cater to; if you're importing a configuration where one of the fields has the same name but different values; e.g. same username different token / ca.

For me it's handy since I'm regularly connecting to 10+ kubernetes clusters and many of them cycle credentials for access.

I think it'd make more sense for it to be a different script though; kubecfg for example? The only challenge I can see which needs overcoming is parsing the YAML to ensure none of the names collide; and if they do ask the user what needs to happen.

$ kubecfg add <path>
$ kubecfg update <name> <path>

or  

$ kubectx -n <path>
$ kubectx -u <name>=<path>

We have some kubectl plugins in Krew (http://krew.dev) already doing this, and there are even desktop tools like https://github.com/turkenh/KubeContext/blob/master/README.md#installation that do similar things.
