Teaching-Docker-SimpleJavaServer

The goal of this repo is to show how to create a Docker image and how to run containers based on this image.

For this purpose, we have implemented a simple TCP server in Java. The source files are provided, but when we build the image, we use the executable jar file that is already available in the repo.

Building the image

There are two ways to build the image:

• one option is to build it locally, by running the docker build command;
• another option to build it on the Docker Hub cloud service

Running a container

To run a container, just use this command:

docker run -p 2205:2205 oliechti/teaching-docker-simplejavaserver

Exploring the image, via a new container

To log into a new container started from the image, use this command:

docker run -it -p 2205:2205 oliechti/teaching-docker-simplejavaserver /bin/bash
