title: Ansible: create a user with sudo privileges
body: <p>I have taken over a Ubuntu 14.04 server. It has a user called "deployer" (used with capistrano), and as such, it needs sudo privileges. With this setup, I can log into the server and do stuff like:</p>
  
  <pre><code>workstation&gt; ssh deployer@myserver
  myserver&gt;  sudo apt-get install git
  myserver&gt; exit
  workstation&gt;
  </code></pre>
  
  <p>I am trying to figure out how to use Ansible (version 2.0.2.0 and python 2.7.3) to create a user called "deployer" and be able to log into the server with that id and then so sudo-ish things like "apt-get install". My playbook looks like this:</p>
  
  <pre><code>---
  - hosts: example
    become: yes
    tasks:
    - name: Update apt cache
      apt:
        update_cache: yes
        cache_valid_time: 3600
  
    - group: name=sudo state=present
  
    - name: Add deployer user and add it to sudo
      user: name=deployer
            state=present
            createhome=yes
      become: yes
      become_method: "sudo"
  
    - name: Set up authorized keys for the deployer user
      authorized_key: user=deployer key="{{item}}"
      with_file:
        - /home/jaygodse/.ssh/id_rsa.pub
  </code></pre>
  
  <p>After running this playbook, I am able to ssh into the machine as "deployer", (e.g. ssh deployer@myserver) but if I run a sudo command, it always asks me for my sudo password. </p>
  
  <p>I understand that the "deployer" user ultimately has to find its way into the visudo users file, but I cannot figure out which magical Ansible incantations to invoke so that I can ssh into the machine as  deployer and then run a sudo command (e.g. sudo apt-get install git") without being prompted for a sudo  password. </p>
  
  <p>I have searched high and low, and I can't seem to find an Ansible playbook fragment which puts the user "deployer" into the sudo group without requiring a password.  How is this done?</p>
