Here is the workflow
There's a demo node application in the index.js file. There are two routes.
\hello
\bye
Now we are gonna make a complete ci/cd pipeline for this application & deploy it in a server. We've some test cases for this application. We'll run those test cases in our ci/cd pipeline. If all the test cases pass, then we'll deploy the application on the server. We'll use GitHub actions for the ci/cd pipeline. We'll use aws ec2 instance as our server.
For the ci part, we'll write a GitHub actions workflow named ci.yml
name: Test
on:
pull_request:
branches:
- master
jobs:
test:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Set up Node.js
uses: actions/setup-node@v2
with:
node-version: "14"
- name: Install dependencies
run: npm ci
- name: Run tests
run: npm run test
This workflow will be triggered when we create a pull request to the master branch. It'll run the test cases & if all the test cases pass, then it'll merge the pull request to the master branch.
For the cd part, we'll write a GitHub actions workflow named deploy.yml
name: Deploy
on:
push:
branches:
- master
jobs:
deploy:
runs-on: self-hosted
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Install dependencies
run: sudo apt install docker-compose -y
- name: Deploy to VM
run: |
sudo docker-compose down -v && sudo docker-compose up -d --build
This workflow will be triggered when we push to the master branch. It'll deploy the application on the server. We have used docker-compose to deploy the application. GitHub will automatically deploy the application in the server when we push it to the master branch. We can configure our server to pull the code from Git Hub & deploy the application automatically by adding our server as a GitHub runner.
We've deployed the application on the server. You can visit the application using this link:
- Fork this repository.
- Go to your repository settings.
- Add your server as a GitHub actions runner (see below).
To add our server as a GitHub actions runner, we need to follow these steps: We can see this when we go to our GitHub repository-> settings->actions -> runner-> self-hosted runner
Just follow the instructions and we'll be able to add our server as a GitHub runner.
- Now follow the instructions above to create the ci/cd pipeline.
