Run Microservices Demo with Vagrant

Vagrant can set up virtual machines to install software on them. In this example Vagrant install Docker on the virtual machine and deploys Docker Containers afterwards.

To run the demo:

• Install Maven, see https://maven.apache.org/download.cgi
• Install Virtual Box from https://www.virtualbox.org/wiki/Downloads
• Install Vagrant as discussed at http://docs.vagrantup.com/v2/installation/index.html
• Go to directory microservice-demo and run mvn package there
• Change to the directory docker-vagrant and run vagrant up. Each time you start the Vagrant VM the Docker containers will be started, too.

The result should be:

• A new VirtualBox VM is fired up by Vagrant
• Docker is installed in the VM
• You can access the application at http://127.0.0.1:18080/ . It has a web page with links to all other services.
• You can access the Eureka dashboard at http://127.0.0.1:18761/
• You can access the Turbine dashboard at http://127.0.0.1:18080/turbine/hystrix . The URL for the data stream of all Hystrix data of all Order nodes is http://172.17.0.10:8989/turbine.stream?cluster=ORDER - the IP-Adresse changes. Look it up in the Eureka dashboard for service turbine. You can also connect to a Hystrix stream of an order service. You need to use the address http://172.17.0.9:8080/hystrix.stream of the Order App. The IP address can be found in the Eureka dashboard.

Additonal hints:

• Use vagrant halt to shut down the system or vagrant destroy to to delete the VM.
• If you wantt login to the VM, please use vagrant ssh.
• If you update the code, you need to rebuild it and then do a new provisioning using vagrant provision . Then the Docker containers in the Vagrant VM will be rebuild.

The following ports will be used on localhost :

• 18080 for the web application
• 18761 for Eureka
• 18989 for the Turbine server
