yamllint: command not found

[till]

Running your action with act currently produces:

[ci/helm-lint]   🐳  docker exec cmd=[bash --noprofile --norc -e -o pipefail /var/run/act/workflow/5-composite-yamllint.sh] user= workdir=

| ======================
| /var/run/act/actions/ibiqlik-action-yamllint@v3.1.1/entrypoint.sh: line 34: yamllint: command not found

This is how I use it:

---
name: ci

on:
  pull_request

jobs:
  helm-lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: ibiqlik/action-yamllint@v3.1.1
        with:
          format: github
          file_or_dir: |
            certmanager
            certmanager-config
            cloudnative-pg
            haproxy-ingress
            postgresql

I found the same problem when use act for local ci test.

Part of my workflows job show:

yamllint-checker:
    needs: changes
    if: |
      (needs.changes.outputs.yaml == 'true')
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Yamllint checker
        uses: ibiqlik/action-yamllint@v3
        with:
          file_or_dir: samples/deploy 
          config_file: .yamllint.yml

I just looked at the action, it seems it doesn't actually install yamllint? I am a bit confused.

I'm facing the same issue in a self hosted runner. I was under the impression this was a docker action (https://docs.github.com/en/actions/creating-actions/creating-a-docker-container-action), but it appears to be a composite action which only runs the entrypoint.sh...

Looks like versions prior to v3 might work. https://github.com/ibiqlik/action-yamllint/releases/tag/v3.0.0

Perhaps the action should verify that yamllint is installed? And if not, install it into a venv that is then destroyed.

I will take a stab at this improvement. If it wouldn't be accepted, please let me know though so I don't waste my time.

I was able to fork this repository and fix it for myself by modifying action.yml to replace

using: 'composite'
steps:
    - run: ${{ github.action_path }}/entrypoint.sh
      shell: bash
      env:
        INPUT_FILE_OR_DIR: ${{ inputs.file_or_dir }}
        INPUT_CONFIG_FILE: ${{ inputs.config_file }}
        INPUT_CONFIG_DATA: ${{ inputs.config_data }}
        INPUT_FORMAT: ${{ inputs.format }}
        INPUT_STRICT: ${{ inputs.strict }}

with

using: 'docker'
image: 'Dockerfile'

If this has no other unwanted side effects, I would like to see this fixed upstream.

Good thinking! The only problem I can see is that this builds the image each time.

I ended up installing into a venv, and destroying the venv afterwards. It's not necessary to destroy after on a GitHub runner, but it could be necessary in a self hosted runner. I'd be happy to submit a PR... if this would be desirable, please let me know.

[atkinsonm]

From what I'm reading, pip installing into a temporary venv as part of the composite action steps seems like the best path forward.
