+
+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.
+
+## Requirements
+
+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](https://expressjs.com/) for the API and [Mongoose](https://mongoosejs.com/) to connect to MongoDB. You can use `nodemon` to automatically restart the server when the source code changes. 
+
+### Requirement #1 - Dockerize the API
+
+You are required to dockerize the API and have a `docker-compose.yml` file which will spin up a [MongoDB container](https://hub.docker.com/_/mongo) 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.
+
+### Requirement #2 - Setup a remote server
+
+Setup a remote server on [Digital Ocean](https://m.do.co/c/b29aa8845df8), 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.
+
+### Requirement #3 - Setup a CI/CD pipeline
+
+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](https://github.com/features/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.
+
+<hr />
+
+After completing this project, you will have a good understanding of Docker Compose, multi-container applications, CI/CD pipelines, and more.
