Install Vagrant

https://www.vagrantup.com/docs/installation/

1. Install VirtualBox

   https://www.virtualbox.org/wiki/Downloads

2. Install Vagrant

   sudo apt install vagrant
   

Set up a new vagrant box

1. See if hashicorp has a box for the latest Ubuntu LTS: https://app.vagrantup.com/hashicorp

   If not, check here: https://app.vagrantup.com/ubuntu

2. Initialize the Vagrant box

   vagrant init ubuntu/focal64
   

   (this will create a Vagrantfile in the local directory)

3. (Optional) Customize the Vagrantfile

   For example, if you wish to specify the amount of CPUs or memory:

   Vagrant.configure("2") do |config|
     config.vm.provider "virtualbox" do |vb|
       vb.memory = 1024
       vb.cpus = 1
     end
   end
   

Start a vagrant box

vagrant up

Mount a local folder inside the vagrant box

The local folder is automatically mounted inside the running vagrant box under /vagrant

Connect to a running vagrant box

vagrant ssh

If it asks for a password, use: vagrant

Shut down a vagrant box

vagrant halt

Delete a vagrant box

vagrant destroy
