How can I integrate GitHub Actions with Docker?

You can integrate GitHub Actions with Docker by creating a workflow file that builds and pushes your Docker images.

What does the workflow 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:latest
      - name: Push Docker image
        run: docker push my-image:latest

Do I need to set up any secrets for Docker Hub?

Yes, you'll need to set up your Docker Hub credentials as secrets in your GitHub repository settings.

How do I add those secrets?

Go to your repository on GitHub, click on 'Settings', then 'Secrets', and add your Docker Hub username and password.
