How can I automate Docker deployments in my CI pipeline?

You can automate Docker deployments in your CI pipeline by using tools like Jenkins, GitLab CI, or GitHub Actions. Would you like a step-by-step guide?

Yes, please provide a step-by-step guide for GitHub Actions.

First, create a Dockerfile for your application. Then, in your GitHub repository, create a .github/workflows directory and add a YAML file for your workflow. In this file, define the steps to build your Docker image and push it to a container registry.

What should the YAML file look like?

Here's a basic example:

name: CI

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Build Docker image
        run: docker build . -t my-image
      - name: Push Docker image
        run: docker push my-image
