This presentation starts with an introduction to the rationale behind automated deployments in Continuous Delivery and DevOps. Then, I compare agent-based architectures, such as Chef and Puppet with the agentless architecture of the server orchestration engine Ansible. The presentation concludes with an automated deployment of Dynatrace into a simulated production environment.

...which is at the heart of Continuous Delivery, defined as:
“A deployment pipeline is, in essence, an automated implementation
of your application’s build, deploy, test and release process.”

Why?
» Create application runtime environments on demand
» Fast, reliable, repeatable and predictable outcomes
» Consistent environments in staging and production
» Establish fast feedback loops you can react upon
» Makes release days riskless, almost boring

Introduction to Ansible Concepts

57. 57 #Dynatrace
Ansible Concepts: Inventories

58. 58 #Dynatrace
Specify the environment Ansible operates in.
» Groups and hosts are defined in inventories
» Use inventories for staging and production
» Text files expressed in an INI-like format

Ansible Concepts: Playbooks

62. 62 #Dynatrace
Defines sequences of tasks (Plays) to be executed on a group of hosts.
» Describes policies machines under management shall enforce
» Contains variables, tasks, handlers, files, templates and roles
» Expressed in YAML
Ansible Concepts: Playbooks

63. 63 #Dynatrace
--- # webservers.yml
- hosts: webservers
tasks:
- name: Install Apache HTTP Server
apt: name=apache2 update_cache=yes
- name: Install Apache Modules
apache2_module: name={{ item }} state=present
with_items:
- proxy
- proxy_httpd
notify: reload apache2

66. 66 #Dynatrace
Ansible Concepts: Roles

67. 67 #Dynatrace
The best way to organize your playbooks.
» Structure content into related vars, tasks, files, handlers, etc.
» File structure for automated inclusion of role-specific content
» Roles can be shared and pulled from Ansible Galaxy, GitHub, etc.
