Containerize your microservice using Docker

[naveenjustcoder]

As a developer
I need to containerize my microservice using Docker
So that I can deploy it easily with all of its dependencies

Details and Assumptions

• Create a Dockerfile for repeatable builds
• Use a Python:3.9-slim image as the base
• It must install all of the Python requirements
• It should not run as root
• It should use the gunicorn wsgi server as an entry point

Acceptance Criteria

Given the Docker image named accounts has been created
When I use `docker run accounts`
Then I should see the accounts service running in Docker
