Objective

Demonstrate ability to containerize applications, facilitating scalability and simplifying deployment.

Instructions

Given a simple Nest.js backend API source code, Dockerize the application.

1. Ensure the Dockerfile is optimized for build speed and image size.
2. Provide instructions on how to build and run the container, including how to access the API once it's running.
3. Nest.js Repo: https://github.com/nestjs/nest
   • If it’s simpler, feel free to choose the boilerplate for Nest.js

Objective

Implement monitoring tools for observability and downtime alerts.

Instructions

1. Propose a simple monitoring setup for the previous Dockerized application, tracking metrics like CPU usage, memory consumption, response times, and error rates.
2. Suggest a tool (or tools) for monitoring, and describe the reason for the tools that were chosen.
3. Explain how you would configure alerts for downtime or performance degradation.
