![]() Prevent images from being pulled implicitly when creating containers. This option is useful in situations where networking is not available, or to Image is not found, an error is produced, and the container is not created. The never option disables (implicit) pulling images when creating containers,Īnd only uses images that are available in the image cache. ![]() Images, but may not be suitable in situations where you want to test a locallyīuilt image before pushing (as pulling the image overwrites the existing image Option makes sure the image is up-to-date, and prevents you from using outdated The always option always initiates a pull before creating the container.

You can restart a stopped container with all its previous changes intact using docker start. The docker run command runs a command in a new container, pulling the image if needed and starting the container.
