Originally based on a combination of the Digital Ocean How To Configure a Production-Ready Mesosphere Cluster on Ubuntu 14.04 and the Mesosphere Docker on Mesosphere tuturials.
For an overview on Mesos please see:
You only need Vagrant, Virtual Box(or some other Vagrant provider), and Ansible
How to install Vagrant on your system is described at the Vagrant documentation.
How to install Ansible on your system is described at the Ansible documentation.
or if you are on OSX and have homebrew and cask installed.
brew install ansible && brew cask install vagrant virtualboxTo Start all machines
vagrant up After the successful boot-up Mesos UI will be accessible 192.0.2.11:5050
* if 192.0.2.11 is not currently the zookeeper elected mesos leader, it will automatically redirect you.
The Environment below is established in the vagrant file. After deploying the VM's Vagrant generates a inventory of all the machines which is consumed by Ansible for provisioning. This setup utilizes the default vagrant key in ~/.vagrant.d/insecure_private_key and the vagrant userid
| Hostname | Function | Static IP Address |
|---|---|---|
| master1 | Mesos master | 192.0.2.11 |
| master2 | Mesos master | 192.0.2.12 |
| master3 | Mesos master | 192.0.2.13 |
| slave1 | Mesos slave | 192.0.2.51 |
| slave2 | Mesos slave | 192.0.2.52 |
| slave3 | Mesos slave | 192.0.2.53 |
Currently the ansible playbook requires the Master hostnames to each have a different number between 1-255 which is used to set the zookeeper ID for the machine ie. master1 = zookeeper id 1.
##Components
The Mesos masters each have zookeeper, mesos, marathon, and chronos installed and the mesos slaves have mesos and docker installed.
Zookeeper: ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.
Mesos: A distributed systems kernel
Marathon: A cluster-wide init and control system for services in cgroups or Docker containers
Chronos: A distributed and fault-tolerant scheduler replacement for cron
Docker: An open platform for distributed applications for developers and sysadmins.
