This is an application that is a dummy webservice that returns the last update time. The last updated time is cached in redis and resets every 5 seconds. It has a single '/' endpoint. The redis address is passed in through the environment.

NOTE: The following tasks should take no more than 1 hour total.

1. create Dockerfile for this application
2. create docker-compose.yaml to replicate a full running environment so that a developer can run the entire application locally without having to run any dependencies (i.e. redis) in a separate process.
3. explain how you would monitor this application in production. Please write code to do the monitoring.
