yaml-schema-validator-github-action

A GitHub action that uses Yamale for YAML schema validation.

Usage

• Filenames are relative to the repository root.
• Disable strict checking by setting no-strict to true, 1 or yes.
• For help with the schema definitions and reference, see Yamale.

The following example sets up a check to validate a YAML file in your repository, target.yaml, using a schema defined in schemas/schema.yaml:

name: YAML schema validator
on: [push]

jobs:
  yaml-schema-validation:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - uses: nrkno/yaml-schema-validator-github-action@v4
      with:
        schema: schemas/schema.yaml
        target: target.yaml
        # and/or use (optional)
        target-glob-path: a/glob/**/pattern/.yaml
        # Uncomment to disable strict checks
        # no-strict: true

Versioning

This action is meant to be a wrapper around Yamale, so as of version 4.x of Yamale, this action will follow Yamale's major version scheme.

To bind the action to a specific release, suffix with @<tag>. E.g. nrkno/yaml-schema-validator-github-action@v4.
