Step 2: Add a Dockerfile

You created a publishing workflow! 🎉

We will add a Dockerfile to the cd branch. The Dockerfile contains a set of instructions that get stored in a Docker Image. If you'd like, you can learn more about Dockerfiles.

⌨️ Activity: Add a Dockerfile

1. In the cd branch, create Dockerfile at the project root and include:

   FROM nginx:1.24-alpine
   COPY . /usr/share/nginx/html
   

2. Commit your changes.
3. Wait about 20 seconds then refresh this page (the one you're following instructions from). GitHub Actions will automatically update to the next step.
