Vagrant first steps tutorial

Instructions to create a ubuntu virtual machine from scratch.

1. Create a directory for your virtual machine configuration: mkdir my-vm
2. Move to the new directory: cd my-vm
3. Initialize a configuration file: vagrant init
4. Edit the new file 'Vagrantfile' deletig all commented lines: nano Vagrantfile

Vagrant.configure("2") do |config|
  config.vm.box = "base"
end

1. Launch a new virtual machine based on the current Vagrantfile: vagrant up

The proccess will fail due to a bad configuration. There's no "base" box.

1. Edit the Vagrantfile. Change "base" for another valid box name (view boxes on Vagrant Cloud)

Vagrant.configure("2") do |config|
  config.vm.box = "ubuntu/focal64"
end

1. Launch the new virtual machine again: vagrant up
2. Connect to the new virtual machine: vagrant ssh
3. Exit from the new virtual machine: exit
4. Shutdown the new vm: vagrant halt
5. Delete the vm: vagrant destroy
