helm completion does not auto-complete releases or charts

[thomas-riccardi]

helm completion does not auto-complete releases or charts:

# Releases
$ helm ls
NAME            REVISION        UPDATED                         STATUS          CHART           NAMESPACE

$ helm history <TAB>
# suggests local files instead of existing releases

# Charts
$ helm charts <TAB>
# suggests local files only, could also suggest charts from repositories

As an example, kubectl has auto-completion on remote resources, and it's really much more useful than what helm has.

For what it's worth, I also anticipated the completion to be more like kubectl and autocomplete a release name/chart name. The local file thing was unexpected.

The feature is still missing as far as I know.

@Vickey-Wu yes there is a minimal bash auto-completion support in helm, but it does not dynamically auto-completes releases names and such like kubectl does.
I checked the new helm 2.10 version, as well as the changelog, commits and code: there is nothing new: the feature is still missing.

Feel like working on a fix? :)

Bash autocompletion is a feature of spf13/cobra which we turned on but I don't think anyone from the core maintainers use it, so someone from the community more familiar with bash autocompletion would be more suited to the task than we would, quite honestly.

I've looked into how this is done in kubectl and it goes beyond my level of area expertise. I am 🤞 that somebody that has the matching cross section of skills between shell completion and the tools behind the helm/kubectl CLIs comes across this issue.

[marckhouzam]

The completion of releases has been done in #5562 for v2 (part of helm 2.15.0) and by #5829 for v3.

Still more dynamic completions can be added, such as charts, as suggested in this issue.

[marckhouzam]

The completion of charts has been implemented in #6730 for Helm 3.

The two dynamic completions requested in this issue will be part of helm 3 so I feel this issue can be closed.
