Is there a way to create own boilerplate helm chart and then generate from it helm charts for my micro services (which will differ only in chart names)?
Use helm create command to create boiler template, then changes are up to yourself.
$ helm create mychartYes, you'd need to create a package of your base boilerplate chart and then reference it in the requirements.yaml for other charts which depend on it.
