Recap: network concepts in docker

docker container -p we know it exposes the port on our machine.

quick port check with docker container port <container_name>

by default, each container connected to a private network bridge

to make it interconnected through public network (internet) it routes out through NAT firewall, and its configurable through docker daemon

we can attach containers to more than one virtual network,

or we can skip virtual networks and use the host IP using --net=host

also by default, from machine to container, there is a … let’s called a firewall that blocks the incoming traffic.
