Getting all values of a chart without deploying

[delthas]

Hi,

I'd like to get all the values ("COMPUTED VALUES") of a chart (and its dependencies) without deploying it:

• Like helm template, but to get the values instead of the manifests.
• Like helm get values --all, but as if I was using helm template, working on an undeployed chart with a list of passed --set, --values, instead of a deployed release.

eg helm <command> --namespace bar chartname ./path/to/chart --values baz.yaml that would return

COMPUTED VALUES:
global:
 ...
subchart1:
 enabled: true
 ...

Is there a way to do this in Helm?

Note that this is not the same as cat baz.yaml nor cat ./path/to/chart/values.yaml because I also want values of chart dependencies (and their dependencies).

@delthas You could use the --dry-run --debug flags with helm install. Check out Debugging and docs for more details.

OK, that's close enough to what I need! Thanks.

I'm afraid the provided workaround does not gives the initial requirement which is provide the full computed values (including dependencies) of a helm chart.

That means retrieving all .Values.* that can be found in templates (recursively on sub charts), and rebuild the full values.yaml file.

The helm install --dry-run command does not help, since it does not produce any values.yaml file, so we need anyway to parse everything to produce such complete computed values.yaml.
