Update

The docker update command dynamically updates container configuration. You can use this command to prevent containers from consuming too many resources from their Docker host.

Examples:

docker update –cpu-shares 512 23263ad49893

Wait

Block until one or more containers stop, then print their exit codes.

Examples:

start the container in background

docker run -dit –name=poorani1 bash

wait for the container

docker wait poorani1

stop the container in another terminal or console

docker stop poorani1

container wait command will get the exists status.
