Dependencies
------------

- https://github.com/geerlingguy/ansible-role-java
 - https://github.com/AnsibleShipyard/ansible-zookeeper
 - https://github.com/AnsibleShipyard/ansible-mesos
 - HAProxy installed for HAProxy support

Example Playbook
----------------

```yaml
- hosts: all
  tasks:
    - name: Installing repo for Java 8 for Debian
      apt_repository: repo='ppa:openjdk-r/ppa'
      when:
        - ansible_os_family == 'Debian'
        - ansible_distribution_version|version_compare(16.04, '<')

- name: Install dependencies
  hosts: all
  roles:
    - role: geerlingguy.java
      java_packages:
        - openjdk-8-jdk
      when: ansible_os_family == 'Debian'

- role: geerlingguy.java
      java_packages:
        - java-1.8.0-openjdk
      when: ansible_os_family == 'RedHat'

- role: AnsibleShipyard.ansible-zookeeper
    - role: JasonGiedymin.mesos
      mesos_install_mode: master-slave

- role: JasonGiedymin.marathon
```

HAProxy Support
----------------

A cron job is configured to run the haproxy_dns_cfg script which will query
the marathon api for applications and setup the appropriate frontend (listening on port 80)
with backends for each application.
HAProxy will look for a hostname prefixed with the application name and route to that backend.
Using this technique you can wildcard a dns host to all your masters
(say, *.example.com) and an application you launch (say, "myapp") will be
available at myapp.example.com. This can be disabled by setting the haproxy_script_location
to an emptry string ```""```. It will only be installed if HAProxy is present.
