Forcing ansible playbooks to concrete hosts (and vagrant version)

This is a fast workaround to force to run a playbook to a concrete host.
Important: You must to have the host added to the ansible host inventory.

You will need to convert hosts to a variable. From:

- name: Installing base server template
  hosts: all
  gather_facts: true
  roles:
   - base
   - ntpenabled


To:

- name: Installing base server template
  hosts: '{{ hosts }}'
  gather_facts: true
  roles:
   - base
   - ntpenabled

And now, in terminal for running the playbook:

ansible-playbook <playbook.yml> --extra-vars="hosts=<ip_or_hostname_here>"


and for vagrant:

  config.vm.define "test" do |test|
     test.vm.box = "chef/centos-6.6"
     test.vm.network "private_network", ip: "10.1.1.13"
     test.vm.provision "ansible" do |ansible|
       ansible.playbook = "ansible/playbooks/base.yml"
       ansible.sudo = true
       ansible.extra_vars = {
          hosts: "ip_or_hostname_here"
       }
     end
  end
