Ansible - Getting started	Ansible

Install Ansible

$ brew install ansible            # OSX
$ [sudo] pip install ansible      # elsewhere

Start your project

~$ mkdir setup
~$ cd setup

Create an inventory file

This is a list of hosts you want to manage, grouped into groups. (Hint: try using 127.0.0.1 to deploy to your local machine)

; ~/setup/hosts
[sites]
127.0.0.1
192.168.0.1
192.168.0.2
192.168.0.3

Create your first Playbook

# ~/setup/playbook.yml

- hosts: 127.0.0.1
  user: root
  tasks:
    - name: install nginx
      apt: pkg=nginx state=present

    - name: start nginx every bootup
      service: name=nginx state=started enabled=yes

    - name: do something in the shell
      shell: echo hello > /tmp/abc.txt

    - name: install bundler
      gem: name=bundler state=latest

Run it

~/setup$ ls
hosts
playbook.yml

~/setup$ ansible-playbook -i hosts playbook.yml
