Nanoservice WAR Demo

German / Deutsch

This project creates a VM with the complete nanoservices system in a Docker container. The services are implemented in Java using Spring Boot.

It uses three nanoservices:

• Order to process orders.
• Customer to handle customer data.
• Catalog to handle the items in the catalog.

Each nanoservice is a WAR file. They share a Tomcat to server to run on.

How To Run

• Install Maven, see https://maven.apache.org/download.cgi
• Install Docker, see https://docs.docker.com/installation/
• Install Virtual Box from https://www.virtualbox.org/wiki/Downloads
• Install Docker Machine, see https://docs.docker.com/machine/#installation
• Go to directory war-demo and run mvn package there
• Execute docker-machine create --virtualbox-memory "4096" --driver virtualbox dev . This will create a new environment called devwith Docker Machine. It will be virtual machine in Virtual Box with 4GB RAM.
  • Execute eval "$(docker-machine env dev)" (Linux / Mac OS X) or docker-machine.exe env --shell powershell dev (Windows, Powershell) / docker-machine.exe env --shell cmd dev (Windows, cmd.exe). Now the docker tool will use the newly created virtual machine as environment.
• Change to the directory war-demo and run docker build --tag=war-demo .followed by docker run -p 8080:8080 war-demo.

The result should be:

• Docker Machine creates a new Virtual Box VM with Docker installed.

• Docker images are created and run on that VM.

• Use docker-machine ip dev to find the IP adress of the virtual machine.

• You can access the application at http://ipadresss:8080/order/ , http://ipadresss:8080/catalog/ and http://ipadresss:8080/customer/ . It has a web page with links to all other services.

• Use docker-machine rm dev to destroy the virtual machine.
