Topic #: 6
You want to create a container that is reachable from its host's network. Does this action accomplish this?
Solution: Use --link to access the container on the bridge network.
= The action of using--linkto access the container on the bridge network doesnotaccomplish the goal of creating a container that is reachable from its host's network.The--linkoption allows you to connect containers that are running on the same network, but it doesnotexpose 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 hostoption, which attaches the container to the host's network stack and makes it share the host's IP address2.Alternatively, you can use the--publishor-poption to map the container's ports to the host's ports3.
