Generating the shell autocompletion files reqires a valid kubeconfig

[kastl-ars]

Dear maintainers,

I found kubectl-rook-ceph and wanted to package it for openSUSE. Unfortunately creating the shell completion using the kubectl-rook-ceph completion xyz commands errors out due to a missing kubeconfig:

[   30s] Executing(%install): /usr/bin/bash -e /var/tmp/rpm-tmp.iKAS6L
[   30s] + umask 022
[   30s] + cd /home/abuild/rpmbuild/BUILD
[   30s] + /usr/bin/rm -rf /home/abuild/rpmbuild/BUILDROOT/kubectl-rook-ceph-0.9.3-0.x86_64

[   30s] + mkdir -p /home/abuild/rpmbuild/BUILDROOT/kubectl-rook-ceph-0.9.3-0.x86_64/usr/share/bash-completion/completions/
[   30s] + /home/abuild/rpmbuild/BUILDROOT/kubectl-rook-ceph-0.9.3-0.x86_64//usr/bin/kubectl-rook_ceph completion bash
[   30s] Error: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable
[   30s] error: Bad exit status from /var/tmp/rpm-tmp.iKAS6L (%install)

Creating an empyt ~/.kube/config file does not work.

Most of the tools that provide generation of shell completions do not require a kubeconfig for that, similar to being able to call -help or help or --help subcommands without requiring a configuration file.

Could this be changed in kubectl-rook-ceph, too?

Thanks in advance,
Johannes

@kastl-ars sometime back tried command completion for krew plugin it was not available at that time. But I think it's been long time I can give it try again

That would be great. Just to be clear, there is an existing completion subcommand. I think that those completions only work when the executable is called directly, not via kubectl rook-ceph.
