Our first playbook

Equipped with the basic rules explained previously and assuming readers have done a quick dive into YAML fundamentals, we will now begin writing our first playbook. Our problem statement includes the following:

1. Create a devops user on all hosts. This user should be part of the devops group.
2. Install the "htop" utility. Htop is an improved version of top—an interactive system process monitor.

- hosts: all
  remote_user: vagrant

  tasks:
  
  - group:
      name: devops
      state: present

      uid: 2001
      group: devops
  - name: install htop package
    action: apt name=htop state=present update_cache=yes

- hosts: www
  user: vagrant
