Installation

1. Install package:

npm install --save-dev mongodb-ci-checker

1. Add script to package.json:

"scripts": {
  "mongodb:ci:checker": "node ./node_modules/mongodb-ci-checker/lib",
  ...
},

1. Add task to GitHub CI workflow YAML file:

mongodb-ci-checker:
  name: MongoDB CI Checker
  timeout-minutes: 30
  runs-on: ubuntu-18.04
  steps:
    - uses: actions/checkout@v2
    - uses: actions/setup-node@v1
      with:
        node-version: 10
  - name: Install dependencies
    run: npm ci
  - name: Run MongoDB CI Checker
    run: npm run mongodb:ci:checker
    env:
      MONGODB_CI_CHECKER_VERSION_KEY: [...]
      MONGODB_CI_CHECKER_ENV_KEY_PATH: [...]
      MONGODB_CI_CHECKER_YAML_PATH: [...]
      MONGODB_CI_CHECKER_IGNORE_VERSIONS: [...]

Configuration

The check is configured via environment variables in the GitHub workflow YAML file:

Environment Variable	Type	Optional	Default	Example Value	Description
MONGODB_CI_CHECKER_VERSION_KEY	String			'MONGODB_VERSION'	The name of the environment variable which sets the MongoDB version used for tests.
MONGODB_CI_CHECKER_ENV_KEY_PATH	String			'jobs.tests.strategy.matrix.include'	The YAML key path to the list of environments which should be checked.
MONGODB_CI_CHECKER_YAML_PATH	String			'./.github/workflows/ci.yml'	The file path to the GitHub CI YAML file.
MONGODB_CI_CHECKER_IGNORE_VERSIONS	Array<String>	yes	[]	'["~4.7.0","<4.0.0"]'	The versions to ignore when checking the versions of MongoDB; accepts semver notation.

Example

This is an example configuration, where for each of the test environments the MongoDB CI Checker will ensure that the MONGODB_VERSION set as environment variable is the latest available patch version and there are environments that cover all recent MongoDB versions.

        run: npm test

As defined above, the tests will be executed in environments with the following MongoDB versions:

• 4.4.3
• 4.2.12
• 4.0.22

The MongoDB CI Check will fail, if:

• There is a newer MongoDB patch version available, such as 4.4.4, 4.2.13 or 4.0.23.
• There is a newer MongoDB minor version available, such as 4.5.x.
• There is a newer MongoDB major version available, such as 5.x.x.

The MongoDB CI Check will not fail, if:

• There is a newer MongoDB version 4.7.x available because it is excluded in MONGODB_CI_CHECKER_IGNORE_VERSIONS.
• There is no environment defined with a MongoDB version <4.0.0 because versions below the smallest defined minor version 4.0.22 are automatically ignored.

Note:

• Available MongoDB pre-release versions such as release candidates (x.y.z-rc0) or alpha/beta versions (x.y.z-alpha01) are ignored.
