Transcript
and infrastructure as code workshop Andreas Mosti
Key takeaways • Infrastructure as Code • Configuration Management •
What can Ansible solve? • What can it not solve? • Enough knowledge to understand the key principles

None
Inconsistent server farms
Platform requirements, «What are we releasing on?»
«We need new environments quickly, in a reproducible fashion»
Automate the infrastructure
Snowflake vs. Phoenix Servers
Infrastructure as code:
Reproducible Environments
Servers in version control
Configuration management
Explicit process
Safety!
Code Review
Baked vs. Fried servers
The usual suspects
None
None
Why Ansible?
None
None
Open Source
SSH WinRM
Most important:
The correct abstraction (for us)
None
Playbooks push Database Appserver Load Balancer
None
Remember: Ansible keeps state
The benefits of Infrastructure as Code: 1) Automation 2) Version
control 3) Code Review 4) Testing 5) Documentation 6) Reuse
The holy grale: Imutable infrastructure
Warning 1:
None
None
None
None
The files don’t represent reality!
None
Warning 2:
If not run often, the system might regress
Part 1: Inventory and connection
SSH WinRM
WinRM Port 5986 Local / AD admin user w. remoting
Powershell 3.0 ConfigureRemotingForAnsible.ps1
SSH Port 22 root / dedicated user(s)
None
None
The Inventory
inventory/Example.inventory
inventory/Testlab18.inventory
Exercise 1: Inventory and server connection
Part 2: Playbooks and tasks
Playbooks push Database Appserver Loadbalancer
LoadBalancer.yaml Zookeeper.yaml Solr.yaml Database.yaml ArenaAppServer.yaml
WebServer.yaml
WebServer.yaml
WebServer.yaml
WebServer.yaml
roles/DotNet461/tasks/main.yaml
None
None
Exercise 2: Playbook and simple tasks
Part 3: Roles and variables
WebServer.yaml
To reuse tasks or implement components, we make roles
Example roles: • IIS • DotnetFramework45 • Oracle12C • TeamcityAgent
• Java • GoogleChrome • SplunkForwarder
None
Buildserver.yaml
roles/Oracle12Driver/tasks/main.yaml
roles/Oracle12Driver/tasks/main.yaml
roles/Oracle12Driver/defaults/main.yaml
Lists and iterators
roles/Zookeeper/tasks/main.yaml roles/Zookeeper/defaults/main.yaml
A word on variable precendence
From least to most important: • role defaults • group_vars/
• host_vars/ • host facts • play vars • include_vars • set_facts • extra vars
A word on state and idempotency
Always pick modules over shell commands (if possible)
roles/MKDocs/tasks/main.yaml
roles/MKDocs/tasks/main.yaml
Exercise 3: Roles, variables and iterators
Part 4: Handlers, templates, files
None
Files vs Templates
roles/TeamCityAgent/tasks/main.yaml
True configuration management with templating and JINJA2
roles/TeamCityAgent/templates/buildAgent.properties
roles/SplunkForwarder/templates/input.conf.j2
roles/HAProxy/templates/haproxy.conf.j2
roles/Prometheus/templates/alertmanager.yml.j2
roles/Prometheus/defaults/main.yml
roles/TeamCityAgent/tasks/main.yaml
roles/TeamCityAgent/handlers/main.yaml
Exercise 4: Templates, handlers and files
Part 5: Ansible Vault

roles/TeamCityAgent/defaults/main.yaml
None
roles/TeamCityAgent/defaults/main.yaml
