Krew completion (for fish, likely others as well) only works if ln -s kubectl-krew krew, and even then not in kubectl krew

#769 similar issue

When installing krew as per https://krew.sigs.k8s.io/docs/user-guide/setup/install/, for Fish (but it's likely similar for other shells),

and then activating completion like this:

$HOME/.krew/bin/kubectl-krew completion fish > $HOME/.config/fish/completions/kubectl-krew.fish

then kubectl krew ... still doesn't auto-complete. However if doing:

ln -s $HOME/.krew/bin/kubectl-krew $HOME/.krew/bin/krew

then at least krew ... auto-completes.

and then activating completion like this:

as suggested to be added to the doc in #811, as at least a first step

Krew doesn't offer completion, because kubectl plugins don't support completion yet.

If it appears like krew does have completion scripts, it's a side effect of the library we use, not by design.

also the next time we publish a new version the completion command won't be there #771

With the latest kubectl version (1.26), the kubectl plugins completion now works!

To enable completion for kubectl krew, run the following commands:

echo '#!/bin/sh\nkubectl krew __complete "$@"' >~/.krew/bin/kubectl_complete-krew
chmod u+x ~/.krew/bin/kubectl_complete-krew

@maelvls we should probably implement a native feature for this in the plugin manifest. Do you mind opening a separate issue so I don't forget?

[maelvls]

I think #812 covers this 👍

For anyone using zi or zinit, this is a workaround.

from"{{ choose_github_mirror() }}" is a ansible template, you can remove it if there is nothing blocking access to github.

@maelvls this is how it works for me and thank you for the hack ))
echo -e '#!/bin/bash\nkubectl krew __complete "$@"' >~/.krew/bin/kubectl_complete-krew
chmod u+x ~/.krew/bin/kubectl_complete-krew
