Running a simple client server program in docker

General
2

Looks like you’re pretty close, just need to revise a bit to fit Docker’s networking model.

I’d suggest creating a user-defined network and using that to connect them. You can access containers in the same network via DNS entries (one for each container name).

Here’s an example to explain. In your case you will configure the client container to connect to the server DNS entry server (similar to how myserver is used below).

$ docker network create javaapp

$ docker run -d --net javaapp --name myserver nginx

$ docker run --net javaapp nathanleclaire/curl curl myserver:80
