Skaffold: How to set Helm setValues via env vars

How to set Helm setValues via env vars ?

Tried many variants:
ex:

          setValues:
            ingress.hosts[0]: {{.MYVAR}}   <--- not parsed
            image.pullPolicy: Never

Found this while searching for other things, hopefully it's still correct: https://github.com/GoogleContainerTools/skaffold/pull/347/commits/2da2629042c401fd901797db41506fd53e2c7aea
(not tested)

  setValues:
        some.other.key: ${PWD}/mypath

Skaffold version v0.36.0

Tried all below also, did not work!

export MYVAR=Never
```setValues:
image.pullPolicy: ${MYVAR} <---- did not parse env var

```setValues:
            image.pullPolicy: "${MYVAR}"   <---- did not parse env var

```setValues:
image.pullPolicy: '${MYVAR}' <---- did not parse env var

```setValues:
            image.pullPolicy: {{.MYVAR}}   <---- did not parse env var

setValues: image.pullPolicy: "{{.MYVAR}}" <---- did not parse env var
Error: release ms-backend-local-dev failed: Deployment.apps "ms-backend-dev" is invalid: spec.template.spec.containers[0].imagePullPolicy: Unsupported value: "${MYVAR}": supported values: "Always", "IfNotPresent", "Never"

@emichaf @devronhansen Have you tried setValueTemplates instead of setValues. This should support env variables interpolation.

I'm going to close this issue. I've just checked that it works well with this syntax:

          setValueTemplates:
            ingress.hosts[0]: {{.MYVAR}}
            image.pullPolicy: Never
