[yashbhutwala]

Affected builder image

(e.g., gcr.io/cloud-builders-community/helm)
gcr.io/cloud-builders-community/helmfile

Expected Behavior

helm diff plugin is installed and works out of the box.

Actual Behavior

EXIT STATUS

STDERR:
  Error: unknown command "diff" for "helm"
  Run 'helm --help' for usage.

COMBINED OUTPUT:
  Error: unknown command "diff" for "helm"
  Run 'helm --help' for usage.

Steps to Reproduce the Problem

1. gcloud builds submit --config cloudbuild.yaml .

2. yaml

  - name: "gcr.io/$PROJECT_ID/helmfile"
    # entrypoint: "bash"
    # args:
    # - '-eEuox'
    # - 'pipefail'
    # - '-c'
    # - |-
    #   whoami
    #   env
    #   helm plugin list
    #   helm env
    #   # helm plugin install https://github.com/databus23/helm-diff
    #   # helm plugin list
    args:
      [
        "--file",
        "gcloud/development/helmfile.yaml",
        "diff",
        "--context",
        "1",
      ]

Not sure if there is something weird with the image or whether a bug with GCP CloudBuild, since it changes the home from /root to /builders/home and as a result helm cannot see that the plugin is downloaded.

hmh, the same just happens to me

solved, probably in a bad way but I did not have a lot of time.

added the following to the beginning of the entrypoint helmfile.bash

mkdir -p $HOME/.local/share/helm
ln -s /root/.local/share/helm/plugins $HOME/.local/share/helm/plugins
