Introduction

This GitHub Action starts a MongoDB server or MongoDB replica set. By default, the MongoDB server is available on the default port 27017. You can configure a custom port using the mongodb-port input. The examples show how to use a custom port.

The MongoDB version must be specified using the mongodb-version input. The used version must exist in the published mongo Docker hub tags. Default value is latest, other popular choices are 4.2, 4.4, 5.0 or 6.0.

This is useful when running tests against a MongoDB database.

Usage

A code example says more than a 1000 words. Here’s an exemplary GitHub Action using a MongoDB server in versions 4.2 and 4.4 to test a Node.js app:

name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x, 16.x, 18.x]
        mongodb-version: ['4.2', '4.4', '5.0', '6.0']

    steps:
    - name: Git checkout
      uses: actions/checkout@v3

    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v3
      with:
        node-version: ${{ matrix.node-version }}

    - name: Start MongoDB
      uses: supercharge/[email protected]
      with:
        mongodb-version: ${{ matrix.mongodb-version }}

    - run: npm install

    - run: npm test
      env:
        CI: true

Using a Custom MongoDB Port

You can start the MongoDB instance on a custom port. Use the mongodb-port: 12345 input to configure port 12345 for MongoDB. Replace 12345 with the port you want to use in your test runs.

The following example starts a MongoDB server on port 42069:

name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x, 16.x, 18.x]
        mongodb-version: ['4.2', '4.4', '5.0', '6.0']

    steps:
    - name: Git checkout
      uses: actions/checkout@v3

    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v3
      with:
        node-version: ${{ matrix.node-version }}

    - name: Start MongoDB
      uses: supercharge/[email protected]
      with:
        mongodb-version: ${{ matrix.mongodb-version }}
        mongodb-replica-set: test-rs
        mongodb-port: 42069

    - name: Install dependencies
      run: npm install

    - name: Run tests
      run: npm test
      env:
        CI: true

With a Replica Set (MongoDB --replSet Flag)

You can run your tests against a MongoDB replica set by adding the mongodb-replica-set: your-replicate-set-name input in your action’s workflow. The value for mongodb-replica-set defines the name of your replica set. Replace your-replicate-set-name with the replica set name you want to use in your tests.

The following example uses the replica set name test-rs:

name: Run tests

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x, 16.x, 18.x]
        mongodb-version: ['4.2', '4.4', '5.0', '6.0']

    steps:
    - name: Git checkout
      uses: actions/checkout@v3

    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v3
      with:
        node-version: ${{ matrix.node-version }}

    - name: Start MongoDB
      uses: supercharge/[email protected]
      with:
        mongodb-version: ${{ matrix.mongodb-version }}
        mongodb-replica-set: test-rs
        mongodb-port: 42069

    - name: Install dependencies
      run: npm install

    - name: Run tests
      run: npm test
      env:
        CI: true

With Authentication (MongoDB --auth Flag)

Setting the mongodb-username and mongodb-password inputs. As per the Dockerhub documentation, this automatically creates an admin user and enables --auth mode.

The following example uses the username supercharge, password secret and also sets an initial supercharge database:

name: Run tests with authentication

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [14.x, 16.x, 18.x]
        mongodb-version: ['4.2', '4.4', '5.0', '6.0']

    steps:
    - name: Git checkout
      uses: actions/checkout@v3

    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v3
      with:
        node-version: ${{ matrix.node-version }}

    - name: Start MongoDB
      uses: supercharge/[email protected]
      with:
        mongodb-version: ${{ matrix.mongodb-version }}
        mongodb-username: supercharge
        mongodb-password: secret
        mongodb-db: supercharge

    - name: Install dependencies
      run: npm install

    - name: Run tests
      run: npm test
      env:
        CI: true

Caveat: due to this issue, you cannot enable user creation AND replica sets initially. Therefore, if you use this action to setup a replica set, please create your users through a separate script.
