Description:

Would be nice to have Bash completion for the `kustomize` command.

Here's upstream docs for the Bash completion: https://github.com/kubernetes-sigs/kustomize/blob/0be4a61f64004300849fcc588eed168ce54b2581/cmd/config/docs/commands/completion.md

Their Bash completion is done through this library: https://github.com/posener/complete/tree/3627b9843923e3f366bb64a62d8adb0e6c469d83

Looked into the code of Kustomize and a bit of posener/complete, and it seemed to me that there is no easy way to extract the completion file itself. It just wants to install to ~/.bashrc itself.

Seems to me that an okay workaround is to run "kustomize install-completion" and copy-paste the generated completion files manually:

$ cat kustomize.completion.bash
complete -C /usr/bin/kustomize kustomize
$ cat kustomize.completion.zsh
autoload -U +X bashcompinit && bashcompinit
complete -o nospace -C /usr/bin/kustomize kustomize
$ cat kustomize.completion.fish
function __complete_kustomize
set -lx COMP_LINE (commandline -cp)
test -z (commandline -ct)
and set COMP_LINE "$COMP_LINE "
/usr/bin/kustomize
end
complete -f -c kustomize -a "(__complete_kustomize)"
$ cat PKGBUILD | tail -n8
package(){
cd "kustomize-kustomize-v${pkgver}/kustomize"

install -D kustomize "${pkgdir}/usr/bin/kustomize"
install -D kustomize.completions.bash "${pkgdir}/usr/share/bash-completion/completions/kustomize"
install -D kustomize.completions.zsh "${pkgdir}/usr/share/zsh/site-functions/_kustomize"
install -D kustomize.completions.fish "${pkgdir}/usr/share/fish/vendor_completions.d/kustomize.fish"
}

What do you think?
