Docker Certified Associate Certification Training Course - Host Network

The video tutorial explains Docker host networking, where a container shares its network namespace with the host, optimizing performance and handling a large range of ports without network address translation. It contrasts this with Docker's bridge network, which provides isolation for containers. The tutorial includes practical examples, such as running an Nginx container on a host network, and provides commands to verify the setup. Host networking is supported only on Linux hosts and not on Docker Desktop for Mac or Windows.

Explain how host networking eliminates isolation between the Docker host and container.

What command is used to run a container in a host network?
