This Docker Compose file defines three services: alpine-dns, actual_server, and fake_server. It can be used to test for DNS spoofing.

The alpine-dns service is built from the current directory and exposes port 53.

The actual_server service is built from the ./actual_server directory and exposes port 80 within its container. It is connected to the internal network named internal.

The fake_server service is built from the ./fake_server directory and exposes port 80 within its container. It is also connected to the internal network named internal.

An internal network named internal is created as a custom bridge network for communication between the actual_server and fake_server services.

To run this Docker Compose file, use the docker-compose up command in the same directory as the file. To test for DNS spoofing from outside the container, try to resolve example.com using the alpine-dns service and see if it returns the IP address of the fake_server instead of the actual_server.
