To run a container in the background, allowing it to operate independently while freeing up your command line, you can use the -d or --detach switch with the docker run command.

Running a container in detached mode means that you immediately get your command-line back and the standard output from the container is not redirected to your command-line anymore. For example, if you want to run a continuous ping command inside a container, you could use the lightweight Alpine Linux image. Here’s how you can do it using the given terminal command:

docker run -d alpine ping google.com
