Build and Test Docker Image

A very simple Docker Build GH action that builds a python:3.11-alpine image with a Hello World! Python Script For this demo I made it as simple as possible.

How it works

1. Checkout Code
2. Set up Docker Buildx
3. Build Docker image using Dockerfile only locally
4. Run the Docker Image and save the stdout
5. Compare the stdout from the previous step, if the output is correct the image was correctly build. Otherwise exit code 1
