Docker - Containers - Start a Container

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

Docker Start

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 Start: Launch a previously stopped container. 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.
