As I’m a huge fan of Vagrant, this is the Vagrantfile I’m using to create in 1 run 3 nodes docker environment:

# -*- mode: ruby -*-
# vi: set ft=ruby :

# Every Vagrant development environment requires a box. You can search for
# boxes at https://atlas.hashicorp.com/search.
BOX_IMAGE = "bento/ubuntu-20.04"
NODE_COUNT = 3

Vagrant.configure("2") do |config|
  
  if Vagrant.has_plugin?("vagrant-vbguest") then
    config.vbguest.auto_update = false
  end
  config.vagrant.plugins = "vagrant-docker-compose"
  # install docker and docker-compose
  config.vm.provision :docker
  config.vm.provision :docker_compose

  config.vm.box_check_update = false
  
  (1..NODE_COUNT).each do |i|
    config.vm.define "docker_node#{i}" do |subconfig|
      subconfig.vm.box = BOX_IMAGE
      subconfig.vm.hostname = "node#{i}"
      subconfig.vm.network :private_network, ip: "192.168.10.#{i + 100}"
      subconfig.vm.provider "virtualbox" do |vb|
        vb.name   = "docker_node#{i}"
      end

    end
  end
end

Let’s start the creation of the VMs and measure the execution time (in Windows 10 this time 🙂 ):

PS D:\vagrant\docker> Measure-Command { vagrant up }

Days              : 0
Hours             : 0
Minutes           : 10
Seconds           : 28
Milliseconds      : 173
Ticks             : 6281737909
TotalDays         : 0.00727052998726852
TotalHours        : 0.174492719694444
TotalMinutes      : 10.4695631816667
TotalSeconds      : 628.1737909
TotalMilliseconds : 628173.7909

Now if you want to see the status:

vagrant global-status
id       name    provider   state   directory
------------------------------------------------------------------------
00f2ce8  docker_node1 virtualbox running  D:/vagrant/docker
80dda8d  docker_node2 virtualbox running  D:/vagrant/docker
6b7e183  docker_node3 virtualbox running  D:/vagrant/docker

Let’s check the docker version:

PS D:\vagrant\docker> vagrant ssh docker_node1
