Monitoring Containers with Prometheus

For the last six months, the Acme Anvil Corporation has been migrating some of their bare metal infrastructure to Docker containers. It’s time to implement some basic monitoring in the environment. You will handle this in two ways: using `Docker stats` and Prometheus. Your mission is to set up Prometheus and cAdvisor using Docker Compose. You can get more information on Prometheus at [prometheus.io](https://prometheus.io/).
