The 'python_web_app' service  should be built from Dockerfile and specify the port as 5000 4. the 'db_service' should be built from image 'redis:alpine' 5. Add a volume to the 'python_web_app' service that mounts the current directory to the working directory inside the container and set the flask envireonment in debug mode. 6. Visit 'http:localhost:5000" to check weather the Flask application is running fine. The container name of 'python_web_app' service should be 'web_container' and container name of 'db_service' should be 'db_container' Here are the instructions for each of the tasks mentioned: Create a file na...
