# GitHub YAMLlint

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

## Usage

Simple as:

```yaml
- uses: ibiqlik/action-yamllint@v3
```

### Optional 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 will automatically use it.

### Example usage in workflow

```yaml
name: Yaml Lint
on: [push]
jobs:
  lintAllTheThings:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: yaml-lint
      uses: ibiqlik/action-yamllint@v3
      with:
        file_or_dir: myfolder/*values*.yaml
        config_file: .yamllint.yml
```

Or just simply check all yaml files in the repository:

```yaml
name: Yaml Lint
on: [push]
jobs:
  lintAllTheThings:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: yaml-lint
      uses: ibiqlik/action-yamllint@v3
```

Config data examples:

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

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