Docker 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. With a single command, you can place limits on a single container or on many. To specify more than one container, provide space-separated list of container names or IDs

Command example:
docker update –cpus 4 320f02d6f0f7

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

1st terminal
docker wait 320f02d6f0f7
In another terminal, stop the container
Docker stop 320f02d6f0f7
in the 1st terminal it exits returning 0
