Docker top Command

Docker top Command

docker top : View information about the processes running in the container, supports the ps command parameter.

Docker top Syntax

docker top [OPTIONS] CONTAINER [ps OPTIONS]

Containers do not necessarily have a /bin/bash terminal to interactively execute the top command when they are running, and containers do not necessarily have the top command yet, so you can use docker top to implement to see the running processes in the container.

Docker top Examples
