mesosphere-lab is a set of scripts to setup mesosphere on a local cluster of Vagrant boxes. It consists of a Vagrantfile to init and maintain the virtual hardware, and a complete ansible environment that will setup the mesosphere ecosystem on it.
The environment was tested with the following software versions, on MacOS 10.12.4 and Fedora 25. Other versions may also work (especially ansible) but they were not tested.
- ansible (>=2.3.0)
- Vagrant (>=1.8.5)
- VirtualBox (>=5.1.22)
1). Install prerequisites
sudo dnf install VirtualBox vagrant ansible ruby-devel
# ruby-devel is ruby-dev for apt-based systems2). Install the required vagrant plugins
vagrant plugin install vagrant-hostmanager
vagrant plugin install vagrant-vbguest3). Clone the repository and start the VMs
git clone <the repository>
cd mesosphere-lab
vagrant up --provider=virtualboxGo grab a coffee, because this step will take some time.
4). Install mesosphere
cd ansible
ansible-playbook provision.ymlThis will also take some time, depending on your internet connection speed.
5). After the installation finishes, the following will be available:
On this point, you can start deploying applications on Marathon.
The whole system is based on two nodes, but it can be easily expanded and upscaled to test Mesos scaling capabilities.
Assume that you wish to add a new node named node3:
1). First, add the new node to Vagrantfile, in the cluster section, and provide a suitable IP:
cluster = {
"node1" => { :ip => "192.168.70.10", :cpus => 2, :mem => 2048, :cpucap => 30 },
"node2" => { :ip => "192.168.70.11", :cpus => 2, :mem => 2048, :cpucap => 30 }
"node3" => {:ip => "192.168.70.12", :cpus => 2, :mem => 2048, :cpucap => 30 }
}
2). Add the node to mesosphere-lab/ansible/hosts file, in whichever sections you wish. E.g, in order to make the node be a mesos-master and a mesos-slave, add it to both sections:
[mesos-masters]
node1
+node3
[mesos-slaves]
node1
node2
+node33). Reprovision:
