Make kubectl-prompt suitable for use with zsh

[grzesuav]

Is your feature request related to a problem? Please describe.
Currently it is impossible to use kubectl-prompt with zsh because :

• function definition does not work in zsh
• changes are kept in .bash_profile

Describe the solution you'd like

• change function kubectl () definition to be both bash and zsh compatibile
• store configuration (cluster, namespaces, function definition) outside .bash_profile
• source configuration (from above) in .bash_profile or .zshrc (depending on shell)

Additional context
Currently when I extracted configuration to separate file and try to source it in zsh I get

kubectl: command not found: kubectl () {\n\tkube=$(which kubectl) \n\t$kube prompt "${@}" && command $kube "${@}"\n}

probably because different handling of references in zsh (problematic part : kube=$(which kubectl) inside a function called kubectl)

I created PR with POC for helper function

Thanks @grzesuav, those are some good points. Support for zsh is a reasonable request, and I appreciate the starter PR as well. I will take a look at this when I have time -- hopefully by tomorrow we can have something.

hi @jordanwilson230 , if sth like this is ok with you I can dig it further :

• detection of current shell
• usage of external file (which can be sourced in basrc or zshrc)

Any thoughts from your side ?

[jordanwilson230]

@grzesuav That would be terrific and appreciated. I apologize its taken so long, I've been bogged down in work. I'd love to see what you're able to come up with. Thanks!

+1 to all of this.

looking for support zsh as well, this is a so cool plugin may save my life in future, never mess up prod env.

[jordanwilson230]

Yeah, if anyone wants to contribute to make this happen, that'd be sweet.

Just copy the plugins to /usr/local/bin and it works. No reason to do all this song and dance pollute the PATH crap.
