--hostname, -h=name

Set the container's hostname inside the container.

This option can only be used with a private UTS namespace --uts=private (default). If --pod is given and the pod shares the same UTS namespace (default), the pod's hostname is used. The given hostname is also added to the /etc/hosts file using the container's primary IP address (also see the --add-host option).
