Docker networking allows you to attach a container to as many networks as you like. You can also attach an already running container. Go ahead and attach your running web app to the my_bridge . $ docker network connect my_bridge web. Open a shell into the db application again and try the ping command.
There are three common Docker network types – bridge networks, used within a single host, overlay networks, for multi-host communication, and macvlan networks which are used to connect Docker containers directly to host network interfaces.
You can create multiple networks with Docker and add containers to one or more networks. Containers can communicate within networks but not across networks. A container with attachments to multiple networks can connect with all of the containers on all of those networks.
. NET Core can easily run in a Docker container. Containers provide a lightweight way to isolate your application from the rest of the host system, sharing just the kernel, and using resources given to your application.
i can't seem to find a good explanation for the reason behind using --net vs --network with docker. --help doesn't show --net but only shows --network, can somebody please explain the difference ?
