## Spring Boot example
This example shows how to deploy spring boot application using Apollo and Marathon Mesos framework.
The example includes -
- A custom spring boot application
We'll use the spring-boot Docker image.
The examples are to be deployed on top of the Marathon Mesos framework.
### Start the Spring Boot Application
Start the services by running the following command (from somewhere you can access the REST interface of Marathon). Replace $MARATHON_IP with the actual hostname/ip address of the marathon instance.
Marathon by default should be deployed in the mesos_master nodes.
curl -X POST -HContent-Type:application/json -d @spring-boot.json http://$MARATHON_IP:8080/v2/apps
The service will be accessible through the HAProxy container (on port 80) at springboot.example.com by default. It is recommended that you set up your own DNS servers / hostname and override the haproxy_domain in ../roles/haproxy/defaults/main.yml.
To access the Spring Boot application, go to the Marathon dashboard at http://$MARATHON_IP:8080/#apps and click on /springboot. You should see an IP address and Port in the service definition, if you click on it you should be redirected to the spring boot application.
If you are deploying this example in the Vagrant environment, simply add the following entry to your host machine in /etc/hosts
172.31.1.14 springboot.example.com
Where 172.31.1.14 is the Agent IP address configured in vagrant.yml
If you access springboot.example.com through your browser that will hit the Haproxy container
running on the agent machine which will forward the traffic to the Drupal docker container.
You can remove the applications straight from the command line by running -
curl -XDELETE http://$MARATHON_IP:8080/v2/apps/springboot
