Getting Started with Vagrant

First setup your vagrant file

To begin, you’ll need to configure your Vagrantfile. You can refer to the official vagrant documentation

First, install Vagrant and VirtualBox using the following commands:

sudo apt install vagrant
sudo apt install virtualbox

Vagrant is a powerful tool that allows you to manage and run virtual machines (VMs) using your preferred virtualization software. While VirtualBox is the most common provider, Vagrant also works seamlessly with other tools like QEMU, virt-manager (via the libvirt provider), or even Docker and VMware. This provides a consistent and efficient way to work with VMs, regardless of the underlying virtualization technology.

How to use vagrant

You need to create a VagrantFile. Here is a simple example:

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/trusty64"
  config.vm.box_version = "20191107.0.0"
end

Example complex config

You can also define multiple machines in a single file to create complex environments:

Vagrant.configure("2") do |config|
  (1..2).each do |i|
    config.vm.define "master#{i}" do |master|
      master.vm.box = "almalinux/9"
      master.vm.network "private_network", ip: "192.168.10.1#{i}"
      # master.ssh.host = "192.168.10.1#{i}"
      master.vm.provision "file", source: "~/.ssh/id_rsa.pub", destination: "~/.ssh/authorized_keys"
      master.vm.provider "virtualbox" do |v|
        v.memory = 4096
        v.cpus = 2
      end
    end
  end
end
