We use the default port for the Flask web server, 5000.

Forwards the exposed port 5000 on the container to port 5000 on the host machine.

Uses an image that's built from the Dockerfile in the current directory.

This Compose file defines two services, web and redis. Now that our Dockerfile for our Flask app is ready we may want to define two services in a Compose file, docker-compose.yaml:

Little thing but later this may help: we can replace:

set the default command for the container to python app.py.

Note that the WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions that follow it in the Dockerfile.
