What to expect from this talk 1. Ansible Overview 2.
Inventories and ad-hoc commands 3. Using Playbooks 4. Playbook crash-course
ANSIBLE OVERVIEW
Ansible Overview • Simple and Straightforward • Human-readable automation language
• Agentless - needs only SSH • Extensive list of built-in modules • Used by Twitter, Atlassian, EA, Spotify, even NASA!
Installation $ brew update $ brew install ansible $ sudo
apt-add-repository -y ppa:ansible/ansible $ sudo apt-get update $ sudo apt-get install -y ansible Detailed installation instructions: do.co/ansible-docs Mac OSX Ubuntu *Windows is not officially supported as controller machine.
Setting up SSH access • Servers should be accessible via
SSH using keypair authentication • It's recommended to have a user with sudo NOPASSWD permission to run the tasks in the server How to configure your SSH access for running Ansible: bit.ly/ansible-ssh
INVENTORIES & AD-HOC COMMANDS
Inventory file #/etc/ansible/hosts [webservers] erikaheidi.com dev-human.com [testservers] 178.62.192.53 95.85.35.248
ad-hoc commands $ ansible all -m ping $ ansible webservers
-a “php -v” $ ansible all -i staging -a “sudo apt-get update” ansible group [-i inventory] [-m module]

USING PLAYBOOKS
A Simple Playbook # playbook.yml --- - hosts: all sudo:
true tasks: - name: Update apt-cache apt: update_cache=yes - name: Install Nginx apt: pkg=nginx state=latest
Running playbooks $ ansible-playbook -i staging -l webservers playbook.yml $
ansible-playbook playbook.yml --list-hosts $ ansible-playbook playbook.yml --list-tasks ansible-playbook [-i inventory] [-l group] playbook.yml
DEMO 2 ansible-playbook

THE PLAYBOOK CRASH-COURSE
Variables --- - hosts: all sudo: yes vars: web_server: nginx
tasks: - name: Install {{ web_server }} apt: pkg={{ web_server }} state=latest
Variables (facts) • Information discovered from systems • Globally available
• Example: ansible_default_ipv4.address
Loops (with_items) tasks: - name: Install Packages apt: pkg={{ item
}} state=latest with_items: - nginx - php5-fpm - git
Loops (with_items) --- - hosts: all sudo: yes vars: sys_packages:
[ 'nginx', 'php5-fpm', 'git' ] tasks: - name: Install Packages apt: pkg={{ item }} state=latest with_items: sys_packages
Conditionals - name: "shutdown Debian flavored systems" command: /sbin/shutdown -t
now when: ansible_os_family == "Debian" - name: check if bar is defined fail: msg="This play requires 'bar'" when: bar is not defined
Templates <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot {{ doc_root }} <Directory
{{ doc_root }}> AllowOverride All Require all granted </Directory> </VirtualHost>
Templates - Usage - name: Change default apache vhost template:
src=templates/apache.tpl dest=/etc/apache2/sites-available/000-default.conf
Handlers (services) vars: - doc_root: /vagrant tasks: - name: Change
default apache vhost template: src=templates/apache.tpl dest=/etc/apache2/sites-available/000-default.conf notify: restart apache handlers: - name: restart apache service: name=apache2 state=restarted
