#devops #tutorial #docker #githubactions

📌Prerequisites:

Github account
Dockerhub account
Web repository for dockerize

The web repository could be any of you wish

🎯Workflow

1️⃣Build🧱 & Test🧪
2️⃣Dockerize🐳 the web project
3️⃣Upload💹 image to your docker hub account

1️⃣Build🧱 & Test🧪

Why do what others have already done?

Github Actions has a marketplace where you can find🔎 any pipeline that any other developer has developed.

Writing✏ the pipeline

Inside repo -> Click in Actions

Create the workflow -> Enter New workflow
Search for a NodeJs pipeline

Adjust the pipeline to your needs An example of my pipeline stages

2️⃣Dockerize🐳 the web project

So, if you want to contain the application, you just have to write a dockerfile

🚨 Packing the NodeJs project

Create a dockerfile.ci at the root project directory

FROM node:18
WORKDIR /usr/src/app
COPY package.json package-lock.json ./
COPY app.js ./
RUN npm install
#web port
EXPOSE 8000
CMD ["node", "app.js"]

3️⃣Upload💹 image to your docker hub account

Go to github marketplace🛒
Looking for build and push dockerhub

I like this pipeline

#Name of Job
 to_dockerhub:
    runs-on: ubuntu-latest
    #Wait for ending test process
    needs: test

    steps:

    - uses: actions/checkout@v3
      name: Check out code

    - uses: mr-smithers-excellent/docker-build-push@v6
      name: Build & push Docker image
      with:
        #Name's dockerhub / Name as you want
        image: sharker3312/nodeapp
        tags: v1, latest
        registry: docker.io
        dockerfile: Dockerfile.ci
        username: ${{ secrets.DOCKER_USERNAME }}
        password: ${{ secrets.DOCKER_PASSWORD }}
