#helmfile (2023-07)

So far we’ve been using helmfile.lock in our workflow, but we’ve started using Renovate and adding versions to the helmfile.yaml - however this makes the for some problems in our workflow because the lock isn’t updated by renovate. Is there any reason we need the lockfiles at all when we pin the versions in the helmfile.yaml ?

Hi everybody, I wonder how can CRDS dependencies be managed with helmfile. For example in the same run I am deploying the prometheus op CRDs and the k8s cluster autoscaler (in which values I have a service monitor resource(crd)) . my pipeline make first a helmfile diff and this fail as expected, because that resource does not exist

is there any way to avoid this control ?

I have helmfile.yaml.gotmpl with following simplified content:

---
environments:
  core-01:
    values:
    - envType: prod
      region: <ref+vault://secret/core/service/{{> .Values.envType }}/{{ .Environment.Name }}/s3#/region

---
releases:
- name: some-release
  namespace: some-namespace
  chart: some/chart
  version: 5.0.0
  values:
  - storage:
      backend: s3
      s3:
        endpoint: s3.{{ .Values.region | fetchSecretValue }}.amazonaws.com
        region: {{ .Values.region | fetchSecretValue }}
        bucket_name: <ref+vault://secret/core/service/{{> .Values.envType }}/{{ .Environment.Name }}/s3#/storage

with HELMFILE_V0MODE=true this works fine, but with with HELMFILE_V1MODE=true produces in ./helmfile.yaml.gotmpl: error during helmfile.yaml.gotmpl.part.0 parsing: template: stringTemplate:6:54: executing "stringTemplate" at <.Values.envType>: map has no entry for key "envType". It seems v1 doesn’t allow to reuse env values in other env values. Is this right? What would be refactoring approach to keep things mostly dry?
