MongoDB server

1. start the MongoDB container:

docker run \
  -d \
  -p 27017:27017 \
  --name mongodb \
  --network backend \
  -e MONGO_INITDB_ROOT_USERNAME=mongoadmin \
  -e MONGO_INITDB_ROOT_PASSWORD=secret \
  mongo:latest

Notes:

• -d: run as "detached"
• -p: exposed ports: :
• --name: container name
• --network: network, must be already existing (docker network create <name>)

MongoDB Shell

1. start the Node container:

docker run -it \
  -p 8082:8082 \
  --network backend \
  --name dbclient \
  node:lts-alpine sh

2. disconnect with CTRL+p+q
3. "attach" the container to the frontend network: docker network connect frontend dbclient
4. connect to the client container: docker exec -it dbclient bash
