GitHub YAMLlint

This action executes yamllint (https://github.com/adrienverge/yamllint) against files or folder

Usage

Simple as:

- uses: ibiqlik/action-yamllint@v3

Optional input parameters

• config_file - Path to custom configuration
• config_data - Custom configuration (as YAML source)
• file_or_dir - Enter file/folder (space separated), wildcards accepted. Examples:
  • . - run against all yaml files in a directory recursively (default)
  • file1.yaml
  • file1.yaml file2.yaml
  • kustomize/**/*.yaml mychart/*values.yaml
• format - Format for parsing output [parsable,standard,colored,github,auto] (default: parsable)
• strict - Return non-zero exit code on warnings as well as errors [true,false] (default: false)
• no_warnings - Output only error level problems [true,false] (default: false)

Note: If .yamllint configuration file exists in your root folder, yamllint automatically uses it.

Outputs

logfile - Path to yamllint log file

${{ steps.<step>.outputs.logfile }}

Note: Each yamllint run (for example if you define multiple yamllint steps) has its own log

Example usage in workflow

---
name: Yaml Lint
on: [push]  # yamllint disable-line rule:truthy
jobs:
  lintAllTheThings:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: yaml-lint
        uses: ibiqlik/action-yamllint@v3
        with:
          file_or_dir: myfolder/*values*.yaml
          config_file: .yamllint.yml

Or just simply lint all yaml files in the repository:

---
name: Yaml Lint
on: [push]  # yamllint disable-line rule:truthy
jobs:
  lintAllTheThings:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: yaml-lint
        uses: ibiqlik/action-yamllint@v3

Config data examples:

# Single line
config_data: "{extends: default, rules: {new-line-at-end-of-file: disable}}"

# Multi line
config_data: |
  extends: default
  rules:
    new-line-at-end-of-file:
      level: warning
    trailing-spaces:
      level: warning

Use output to save/upload the log in artifact. Note, you must have id in the step running the yamllint action.
