About

---

This project provides a Ubuntu (14.04) Vagrant Virtual Machine (VM) with Apache Mesos and Marathon setup. It demonstrates running a Python Flask and IPython notebook application. In addition Zookeeper is setup to manage the cluster.

There are Puppet scripts that automatically install the software when the VM is started.

Starting the virtual machine

1. To start the virtual machine(VM) type

   vagrant up
   

2. Connect to the VM

4. Switch to the other pane. Type Ctrl+b, o

5. Start mesos-slave

   sudo ./slave_mesos_start.sh
   

6. Detach from the Tmux session. Type Ctrl+b, d
