The goal of this project is to practice using Docker Compose to run a multi-container application in production. You will use Docker Compose to run a Node.js application and a MongoDB database.
Create a simple unauthenticated Node.js API service for creating a simple todo list. The API should have the following endpoints:
GET /todos — get all todos
POST /todos — create a new todo
GET /todos/:id — get a single todo by id
PUT /todos/:id — update a single todo by id
DELETE /todos/:id — delete a single todo by id
The API should connect to MongoDB to store the todo items. You can use Express for the API and Mongoose to connect to MongoDB. You can use nodemon to automatically restart the server when the source code changes.
You are required to dockerize the API and have a docker-compose.yml file which will spin up a MongoDB container and the API container. If everything works, you should be able to access the API via http://localhost:3000 and the todos should be saved to the MongoDB container. Data should be persisted when the containers are stopped and started.
Setup a remote server on Digital Ocean, AWS or any other cloud provider. You should use terraform to create the server and Ansible to configure it properly i.e. setup docker, docker-compose, pulling the image from Docker Hub and running the containers.
Once you have everything working locally, push your code to GitHub and setup a CI/CD pipeline to deploy the application to the remote server. You can use GitHub Actions to setup the pipeline. Make sure to use docker-compose to run the application in the production environment.
Bonus - Setup a reverse proxy
Setup a reverse proxy using Nginx to allow you to access the application via http://your_domain.com. You should use docker-compose to setup the reverse proxy.
