Containers are start using either the docker start command; or the docker run command.

Docker Start

Launch a container previously stopped. For example, if you had stopped a database with the command

docker stop CONTAINER_ID

, you can relaunch the same container with the command

docker start CONTAINER_ID

, and the data and settings will be the same.

Docker run:

• Create a new container of an image, and execute the container. You can create N clones of the same image. The command is:

  docker run IMAGE_ID

  and not

  docker run CONTAINER_ID

  .
