Join Arthur Ulfeldt for an in-depth discussion in this video Link containers, part of Learning Docker.
- Now let's talk about getting data between containers.…The first approach is to just go out to the host…and then back to the other container.…And then that the other container can go out to the host…and back to the first container.…So you can connect two containers together…by just exposing a port on each of them…and then having each of them connect to the host on that…port which then gets forward into the appropriate container.…Let's take a look at what that looks like.…I'm gonna go ahead and start up a Docker container…to receive some network traffic.…
Docker run --rm -ti ubuntu:14.04 and bash.…Now, I'm gonna go ahead, head on back here…and insert a -p for port.…I wanna forward port 1234 on my laptop to port 1234…inside this container.…So that means traffic arriving at my laptop on 1234…will go into this container.…
Start it up, inside I'm gonna run trusty old net cat,…nc -lp listen port 1234, the same one I just forwarded in…and start it listening.…Okay, this guy's ready to receive some traffic.…Now let's send some traffic to it from another Docker…
