Orchestration and Provisioning with Ansible on Google Compute Engine

This talk focuses on teaching the audience on how to orchestrate and provision servers with Ansible . I focused on Google Compute Engine as the use case for this talk.

The talk was given at Ecole Nationale Superieure Polytechnique de Yaounde at the Big Data and Cloud Conference.

If you would like to know how to get started with Ansible and Google Compute Engine . Read more of my work on KennethKinyanjui.info

1. Orchestration with Ansible on Google Compute Engine Cloud Computing and Big Data Conference Yaounde May 2016 +Kenneth Kinyanjui GDE Cloud Platform @kenju254
5. This talk: - Devops - Orchestration - Ansible - Google Compute Engine
6. The Evolution Ops DevOps
7. Before
8. Credits box.com
9. Before - Engineers used to only code . - Ops guys would deploy on on-site servers - Servers would be on-site
10. Before - Architectures were much simpler - Took a long while to ship the deployment - Very tough and expensive to maintain a data centre
11. Now
13. Now - Servers are on the cloud - Ops guys and Developers working together - Faster rollouts and deployments - More complicated deployment architectures
14. Now - Multiple architectures - Less and lesser decoupling - Easier and Cheaper to manage production instances - New Role - Devops Engineer

16. The Result
17. DevOps
18. What is DevOps ? • Software Development ◦ Code ◦ Test ◦ Deploy • Quality Assurance ◦ Testing ◦ Continuous Integrations • Operations ◦ Orchestration ◦ Logging ◦ Monitoring Credits @jmwai
19. Orchestration
20. The automated arrangement, coordination, and management of complex computer systems, middleware and services From Wikipedia
21. What do we need it for? - Make the maintenance of servers inexpensive - Make it faster to provision servers - Make it easy to deploy complex architectures
22. Tools for Orchestrations - Ansible - Chef - Puppet - Salt-Stack
23. Ansible
24. - According to the creators, Ansible is the simplest way to automate apps and IT infrastructure - Uses YAML syntax. - Configuration details are organised in roles with each roles containing it’s own files, tasks, handlers, vars, templates. - Playbooks contain roles and target hosts. - Plenty of free tested roles available on https://galaxy. ansible.com
26. Vagrant
27. /etc/ansible/hosts
28. Cleaner /etc/ansible/hosts
29. Even more magic
30. Initializing and sending command to you box
31. Example - playbook.yml
32. Recommended Playbook Structure
33. Get started with this recommended playbook here
35. Google Compute Engine
36. https://cloud.google.com/console ://cloud.google.com/console
47. /etc/ansible/hosts ---- GCE IP
48. Define the SSH keys and user for you instance
