    docker exec -it <containder_name> /bin/bash
    
    (/bin/bash or whatever command you want to execute)
    
- Running a container in a specific network with a network alias (so we can reference this name in other containers):

    docker run --name <container_name> --net <network_name> --net-alias <container_netname> -d <image>

- Specify a network in docker-compose file:

    networks:
      default:
        external:
          name: <network_name>

- Create a network:

  docker network create <network_name>
  
- List containers:

  docker ps
  docker container ls
  
- List images:

  docker images
  docker image ls

- Save a container as an image:

  docker commit <options> <image_name>

- Live statistics:

  docker stats
  
- Import/export:
  $ mongodump 
  $ mongoimport
  $ mongorestore
