real usecase :

I have openebs/velero-plugin:2.2.0 installed, but the version 2.3.0 was released yesterday. How can I update it ?

1 - Velero need a way to easily remove any plugin installed

2 - Velero need a way to update a plugin (Could call : delete followed by install). I don't know if the plugin have configuration, but if it's the case, the configuration need to be kept for a update

@carlisia Please consider this as part of CLI/Carvel work

@blackpiglet Was this ever done as part of the Carvel work?

[blackpiglet]

@eleanor-millman No. Velero Carvel package doesn't support modifying plugins. Plugins setting is setup according to the provider by now. Didn't consider this case before. This can be done by adding some new values and conditions checking.

I think it involve two areas of work: 1) Add subcommand to CLI which patches velero pod and restart 2) Evolve the plugin framework of plugin to explore if it's possible to update the plugin binary registration without restarting the pod.

We may resolve this issue if 1) is fixed.
