I just integrated

helm_chart

targets with my repo. First of all, Great job 🎉! I was able to replace a bunch of one-off scripts. Any advice on templatizing or otherwise injecting some values into chart sources? I am specifically thinking of the version fields in

Chart.yaml

and a default image version field in

values.yaml

. We would like to set these values during the release process rather than handle it in source code. A similar idea to using

DOCKER_TAG=<our release tag> ./pants publish src/docker::

in conjunction with

docker.build_args

for injecting the docker tag. A gradle helm plugin I have used in the past allowed templatizing in

Chart.yaml

.. something like

version: ${VERSION}

. Is this something that has been considered? Within the current version of pants, maybe I can create an

experimental_shell_command

target to run

sed

against a

Chart.yaml.template

and configure

helm_chart

sources

to include the output?

Regarding support for interpolation in Chart.yaml, I haven't given it too much thought to be honest. It's defo a possibility. An alternative that we have been using in my company is having a

version

field in the target that would override any version value in the Chart.yaml. It works but it's a bit heavy-handed so I wasn't sure on including it in the first release.

interpolation in values is possible but the way the Docker backend does it is very specific to that backend, may this be a good reason to start to generalize it…? /cc @curved-television-6568

in the meantime, it looks like your workaround could give you that until a better approach
