Solution to Challenge: Running MongoDB Database

Solution

The following command will run the MongoDB:

docker run \
  -it --rm --name mongodb \
  -p 3000:27017 \
  --mount "src=mongodata,target=/data/db" \
  -e MONGO_INITDB_ROOT_USERNAME=root \
  -e MONGO_INITDB_ROOT_PASSWORD=mysecret \
  mongo

• -it runs an interactive session.

• --rm removes the container after the container stops.

• --name is used to name the container as mongodb.

• -p is used to define both the exposed port (left side of :) and the default port (right side of :) on which mongodbis running.

• --mount is used to define persistent Docker volume named mongodata.

• -e allows the setting of required environmental variables. MONGO_INITDB_ROOT_USERNAME sets the root user and MONGO_INITDB_ROOT_PASSWORD sets the root password.

📌 Connect the terminal to see the above command in action.
