This repo is meant for MongoDB drivers to bootstrap their Evergreen configuration files. It contains set of scripts for tasks that most drivers will need to perform, such as downloading MongoDB for the current platform, and launching various topologies.

The bundled .evergreen/config.yml file contains a suggested template for drivers to use. This file can either be taken and used as is, or used as a recipe to copy&paste from.

It is recommended to copy the entire directory and modify the following scripts:

• install-dependencies.sh - Install any platform dependencies not currently available on Evergreen
• run-tests.sh - How to run the test suite
• compile.sh - Configure any alternative environment routes
• compile-unix.sh - Instructions to run the compile stage on *nix
• compile-windows.sh - Instructions to run the compile stage on Windows
• make-docs.sh - Instructions how to compile the driver docs
• make-release.sh - Instructions how to package and release the driver

The normal matrix (e.g. all tasks with the exception on those in the ** Release Archive Creator buildvariant) runs the following two shell scripts:

• The install-dependencies.sh file is always executed by all tasks.
• The run-tests.sh is run by all tasks, except for the ** Release Archive Creator.

The ** Release Archive Creator buildvariant is special, and does not run the "standard test matrix", but in stead runs the following:

• The compile*.sh is executed by the release-compile and release-compile-cmake tasks. These are no commonly used by drivers, so feel free to ignore.
• The make-docs.sh is executed by the make-docs task
• The make-release.sh is executed by the make-release-archive task

This repo also contains a Python package for use in scripts that generate Evergreen config files from Python dicts. See evergreen_config_generator/README.

This repository includes a metadata file for GitHub Actions to allow downloading MongoDB and launching topologies from a GitHub Action Workflow. To use this action, use the following template:

    steps:
      # [...]
      - id: setup-mongodb
        uses: mongodb-labs/drivers-evergreen-tools@master
        # Set configuration
        with:
          version: ${{ matrix.mongodb-version }}

The following inputs exist:

These correspond to the respective environment variables that are passed to run-orchestration.sh.

After the cluster is started, its URI is exposed via the cluster-uri output. This configuration snippet sets an environment variable with the cluster URI returned from the setup-mongodb workflow step when running tests:

    steps:
      # [...]
      - name: "Run Tests"
        run: "run-tests.sh"
        env:
          MONGODB_URI: ${{ steps.setup-mongodb.outputs.cluster-uri }}
