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. Mongo version must be specified in mongodb-version and it must be existing Docker mongo tag. Default value is latest, other popular choices are 4.2, 4.4 and 5.0.
This is useful when running tests against a MongoDB database.
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]
mongodb-version: ['4.2', '4.4']
steps:
- name: Git checkout
uses: actions/checkout@v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node@v2
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: trueYou 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]
mongodb-version: ['4.2', '4.4']
steps:
- name: Git checkout
uses: actions/checkout@v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node@v2
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: trueYou 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]
mongodb-version: ['4.2', '4.4']
steps:
- name: Git checkout
uses: actions/checkout@v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node@v2
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: trueSetting 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]
mongodb-version: ['4.2', '4.4']
steps:
- name: Git checkout
uses: actions/checkout@v2
- name: Use Node.js ${{ matrix.node-version }}
uses: actions/setup-node@v2
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: trueCaveat: 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.
