- Start the RabbitMQ Container:
- docker start rabbitmq-3.6
- Install MQTT Plugin for RabbitMQ:
- docker exec -it rabbitmq-3.6 bash
- rabbitmq-plugins enable rabbitmq_mqtt
- Create the Redis Container:
- docker container create --name=redis -p 6379:6379 redis:alpine
- Start the Redis Container:
- docker start redis
- Create the MongoDB Container:
- docker container create --name=mongodb-3.6 -p 27017:27017 mongo:3.6
- OR, to start the container automatically when they exit, or when Docker restarts.
- docker container create --name=mongodb-3.6 -p 27017:27017 --restart always mongo:3.6
- Start the MongoDB Container:
- docker start mongodb-3.6
Test:
- Check if the containers are running:
- docker ps
- RabbitMQ:
- Open the url http://localhost:15672 and enter `guest` as username and also as password.

- use db_to_remove
- db.dropDatabase()
Superuser Roles

- dbOwner role - when scoped to the admin database
- userAdmin role - when scoped to the admin database
- userAdminAnyDatabase role
- The following role provides full privileges on all resources:
- root role - provides access to the operations and all the resources of the readWriteAnyDatabase, dbAdminAnyDatabase, userAdminAnyDatabase, clusterAdmin, restore, and backup combined
Rename Database
