rancher-vagrant

Vagrantfile for the automated deployment of Rancher 2.0 Technical Preview on VirtualBox.

Pre-requisites

Installation

$ git clone https://github.com/pipoe2h/rancher-vagrant.git
$ cd rancher-vagrant

Configuration

The Rancher platform you get with this Vagrantfile is:

  • Single Rancher master server (2x CPU/2GB memory)
  • Two Rancher node servers (1x CPU/1GB memory)
  • Vagrant box Ubuntu/Xenial64

Before you run vagrant up you should review the Vagrantfile settings to map your requirements.

Vagrant box

BOX_IMAGE = "ubuntu/xenial64" # Rancher recommended OS

Number of Rancher node servers

NODE_COUNT = 2  # Minimum one node. Maximum 244 nodes

Master server hardware

master.vm.provider :virtualbox do |vb|
  vb.memory = 2048  # Recommended 4GB
  vb.cpus = 2
end

Node server hardware

config.vm.provider "virtualbox" do |vb|
  vb.memory = 1024
  vb.cpus = 1
  vb.linked_clone = true
end

Hostname and IP address

master

master.vm.hostname = "master.rancher.local"
master.vm.network :private_network, ip: "192.168.34.10"

node For the node servers provisioning a loop is used. You should only change the three first octets of the IP address 192.168.34. and not the formula #{i + 10}.

node.vm.hostname = "node#{i}.rancher.local"
node.vm.network :private_network, ip: "192.168.34.#{i + 10}"

Usage

$ vagrant up

Depending on your hardware performance and Internet speed, a single Rancher node platform (master is always required) can take around 5-10 minutes to come up.

You can check the Rancher cluster status on http://master.rancher.local:8080/env/1a8/containers (System environment)
