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-demoand runmvn packagethere - Change to the directory
docker-vagrantand runvagrant up. Each time you start the Vagrant VM the Docker containers will be started, too. - Use
vagrant haltto shut down the system orvagrant destroyto to delete the VM. Login to the VM usingvagrant ssh. Do a new provisioning usingvagrant provision. Then the containers will be rebuild.
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.
