The run command creates a container and starts its main process. A name gives you a stable handle for later commands, while detached mode returns the terminal prompt without stopping the application. Options before the image configure the container; words after the image replace or extend its startup command. Check the running state after creation. A downloaded image and a running container are different objects, even when their names look similar. These tasks add configuration gradually, then ask you to start a preview service from a complete request. Keep the requested identity so another operator can find the process.
