Comandos do Vagrant

vagrant staus

Current machine states:

default                   running (virtualbox)

The VM is running. To stop this VM, you can run `vagrant halt` to
shut it down forcefully, or you can run `vagrant suspend` to simply
suspend the virtual machine. In either case, to restart it again,
simply run `vagrant up`.

vagrant validate

Vagrantfile validated successfully.

Cheguei a rodar chmod -R 775 /home/allanramos/Documentos/Projetos/Pessoal/Estudos/ansible/ mas não surtiu efeito.
