Docker - Containers - Start a Container

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

  • Docker Start: Launch a previously stopped container.
    • For example, if you had stopped a container 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.
