This action validates YAML files using the yaml.schemas settings for the VS Code YAML Extension

All you need is a .vscode/settings.json document at the root of the repository that contains the yaml.schemas setting

Location of the schema configuration file.

The default location is .vscode/settings.json, you can change it do a different location but it but still be a json document containing the yaml.schemas config. See the VS Code YAML Extension for how to structure the config.

The yaml.schemas config as inline JSON

Instead of adding the yaml.schemas config to a file, you can instead supply it as inline JSON, e.g.:

      - uses: nwisbeta/validate-yaml-schema@v1.0.3
        with:
          yamlSchemasJson: |
            {
                "http://json.schemastore.org/composer": ["/*"],
                "file:///home/johnd/some-schema.json": ["some.yaml"],
                "../relative/path/schema.json": ["/config*.yaml"],
                "/Users/johnd/some-schema.json": ["some.yaml"],
            }

A comma separated list of files that failed the schema validation.

Schema validation fails if any results are returned from the YAML Language Server
