Creating virtual machines for testing

If you don’t have a spare machine available for testing, you can create it locally, using VirtualBox and Vagrant. Make sure you have both tools installed by following respective guides:

Single node

If you need just one machine, create file named Vagrantfile with the following content:

Vagrant.configure("2") do |config|
  config.vm.box       = "flatcar-stable"
  config.vm.box_url   = "https://stable.release.flatcar-linux.net/amd64-usr/current/flatcar_production_vagrant.box"
  config.ssh.username = 'core'
  config.vm.provider :virtualbox do |v|
    v.memory = 1024
  end
end

Then, run the following commands to create and connect to the machine:

vagrant up && vagrant ssh

Multiple nodes

If you need more than one machine, create file named Vagrantfile with the following content:

Vagrant.configure("2") do |config|
  config.vm.box       = "flatcar-stable"
  config.vm.box_url   = "https://stable.release.flatcar-linux.net/amd64-usr/current/flatcar_production_vagrant.box"
  config.ssh.username = 'core'
  config.vm.provider :virtualbox do |v|
    v.memory = 1024
  end

  config.vm.define "member1" do |config|
    config.vm.hostname = "member1"
    config.vm.network "private_network", ip: "192.168.52.10"
  end

  config.vm.define "member2" do |config|
    config.vm.hostname = "member2"
    config.vm.network "private_network", ip: "192.168.52.11"
  end
end

Then, run the following commands to create the machines:

vagrant up
