= The action of using --link to access the container on the bridge network does not accomplish the goal of creating a container that is reachable from its host's network. The --link option allows you to connect containers that are running on the same network, but it does not expose the container's ports to the host1. To create a container that is reachable from its host's network, you need to use the --network host option, which attaches the container to the host's network stack and makes it share the host's IP address2. Alternatively, you can use the --publish or -p option to map the container's ports to the host's ports3.
