Including files in a helm package - is this possible?

[msmithson-roku]

Helm allows you to load files using .Files.get - https://helm.sh/docs/chart_template_guide/accessing_files/

I can't work out a way to include files in the chart root folder using helm_package (other than Chart.yaml or values.yaml). Without this rules_helm can't be used with chart that use .Files.get as this is not allowed to access files in the templates folder.

Is there a way to do this that I can missing?

This should work as long as the files are inputs to the rule. Can you provide an example of something that works with helm directly but not in rules_helm?

[msmithson-roku]

As far as I can see helm_package does not allow you to specify inputs - other the chart, values or templates.

Try to specify inputs or add the additional files to deps causes errors.

An example is specifying a ConfigMap where the data comes from a file. e.g.

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ .Values.name }}-mappings
  namespace: {{ .Release.Namespace }}
  labels:
    app: {{ .Values.name }}
data:
  mappings.yaml: |-
    {{- .Files.Get "mappings.yaml" | trimSuffix "\n" | nindent 4 }}

For this to work mappings.yaml needs to packaged with the Chart (and not in the templates folder). I can't find a way to do this with rules_helm.

At the moment we are using pkg_tar to add these files to the chart created using helm_package and then using helm_import so we can use it a chart in other rules. Not ideal.

@msmithson-roku - It sounds like this is your issue? #70

[msmithson-roku]

#70 allows templates from multiple locations to be packaged into a chart under the templates folder (which is great!).

However for this use case, we need to include resources that will not be in the templates folder in the packaged chart. (helm specifically prevents you using .Files.Get for with resources that are in the templates folder)

Hello!
Please have a look at #102.
Would appreciate your feedback.

Thanks! Sorry for the delay here. I'll take a look as soon as I have bandwidth!

@abrisco I'm also interested in including a values.schema.json file in my packaged chart. Let me know if I can help get this merged in any way.
