The option that allows containers to share the host's network in the 'docker run' command is indeed the one associated with the host network mode. When using the '--network host' option, the container will share the network stack of the host machine. This means that the container does not get its own IP address; instead, it utilizes the host's IP address and ports directly.

This mode can be particularly useful for performance reasons, as it eliminates the overhead of network address translation (NAT), which is typically involved in the default bridge network mode. It allows the container to communicate over the network without the usual isolation of container networking.

In scenarios where high-performance networking is critical, or when a container needs to communicate with services running on the host without having to route traffic through additional layers, using the host networking mode can be highly advantageous. However, it’s also important to be cautious since this mode bypasses the normal isolation mechanisms provided by Docker, which can lead to conflicts with other services on the host if not managed properly.
