How can I use Docker with GitHub Actions?

You can use Docker in GitHub Actions by defining a Docker container in your workflow file. Would you like a sample workflow?

Yes, please provide a sample workflow.

Here's a simple example:

name: CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    container:
      image: node:14
    steps:
      - uses: actions/checkout@v2
      - run: npm install
      - run: npm test

This workflow runs your tests in a Node.js Docker container.

What if I need to use a custom Docker image?

You can specify your custom image by replacing image: node:14 with your image name. Just ensure it's accessible.
