Overview
Docker set up for express server and mongo

Challenge/Motivation
I decided to get some practice in with Docker locally

Actions Taken

1. Create a network for both containers to use:
   docker network create network-sdc
2. Create the mongodb container:
   sudo docker run --name mongo-sdc -d --network network-sdc -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=<password> -v <your-local-mongodb-data-path>:/data/db mongo
3. Create the node server Docker image:
   sudo docker build . -t node-sdc
4. Create the node server Docker container:
   sudo docker run --name node-sdc -p 49160:3030 --network network-sdc -d -e DB_PASSWORD='<db-password-in-env-file>' node-sdc
5. Check that both containers are running:
   sudo docker containers ls -a
6. Check log file for node server container:
   sudo docker logs node-sdc
7. Curl to an API server route to make sure expected data is returned:
   curl -i localhost:49160/products/1

Results Observed
The most challenging parts were figuring out how to enable authentication for the mongo database in the context of Docker (which required initializing the database with with a root user and password) and making sure to add the password from my .env file intot he container, and also figuring out that I needed both containers to be in the same network.
