beginnerDocker Networking: Bridge, Host, Overlay, DNS & Port Mapping
What happens if you use host networking mode?
The container shares the host's network namespace entirely — it sees the host's network interfaces directly, and any port the application binds to is immediately exposed on the host with no NAT, no isolation, and no port remapping. This maximizes network performance but removes Docker's networking isolation, and a port conflict on the host directly conflicts with the container.
