kubectl-extras's Issues

krew installs an old version of view-secret plugin

Hi,

I have view-secret plugin installed using krew 0.3.0 and I've run into the issue fixed by #4. Turns out that krew installs an older version of the plugin (from before that fix) and believes it's the latest available. I'm not sure what has to be updated where but it would be nice to have the latest version easily available.

Thank you!

[mtail] - add support for pods with multiple containers

Often pods have more than one container. In this case mtails returns :

+ kubectl logs --follow prometheus-main-0 --tail=10
+ kubectl logs --follow prometheus-main-1 --tail=10
Error from server (BadRequest): a container name must be specified for pod prometheus-main-1, choose one of: [prometheus prometheus-config-reloader rules-configmap-reloader]
Error from server (BadRequest): a container name must be specified for pod prometheus-main-0, choose one of: [prometheus prometheus-config-reloader rules-configmap-reloader]

solution :
additional -c parameter to specify container would solve the case

view-secret mapfile dependency

On latest macOS, the system version of Bash is 3.2.57, which does not support mapfile built-in. The script uses a #!/usr/bin/env bash shebang, so it is running via the standard bash, therefore resulting in an error:

❯ kubectl view-secret test-secret
/Users/me/.krew/bin/kubectl-view_secret: line 28: mapfile: command not found

I use ZSH so I have no interest in maintaining a separate bash install via brew, would be very nice if it could be made more portable :)

[mtail] - How to view logs of a namespace and live tail?

I am trying to tail logs of pods in a platform namespace and can't figure out where to specify the platform namespace.

I've tried this so far.

root@1db5fb660216:~# kubectl mtail app=flux 
root@1db5fb660216:~# kubectl -n platform mtail app=flux 
Error: unknown command "mtail" for "kubectl"
Run 'kubectl --help' for usage.
root@1db5fb660216:~#
root@1db5fb660216:~# kubectl mtail app=flux -n platform
The general script's help msg
Usage: /root/.krew/bin/kubectl-mtail [-c|--container <arg>] [-h|--help] <label-selector>
        <label-selector>: Label selector to use, comma separated, i.e. app=prometheus,tier=system
        -c,--container: specify container (no default)
        -h,--help: Prints help
FATAL ERROR: There were spurious positional arguments --- we expect exactly 1 (namely: 'label-selector'), but got 3 (the last one was: 'platform').
root@1db5fb660216:~# 
root@1db5fb660216:~# kubectl mtail -n platform app=flux

Also, is there an option to live tail logs, something like kubectl logs -f <pod_name>

Feature request: Namespace support for view-secret

Great plugins in here! :D
It would be awesome if the view-secret plugin could support namespaces, so I can print out a decoded secret from a namespace other than the one currently set in the context.
