Goal Constraints
•Solaris on prod - Linux on other env
•Non intrusive solutions (OPS)
•Low learning curve (DEV)
•Code Agnostic (JAVA / PHP)
•Flexible and figure out to deal with
existing environments (CI in place)
•Open Source, and innovative
•Sustainable

Why Ansible ?
• unlike puppet and chef Ansible is agent less. No
need to bootstrap nodes
• works with SSH protocol
• can be used in pull or push mode
• Easy Learning curve
• Can handle both Configuration management and
application deployment
• Recipes can read by :
• Dev / Ops,
• Project Supervisor / Project Owner

Why Rundeck ?
•An open source tool to automate
OPS jobs
•Create simple user interfaces to
launch jobs
•REST API
•Jenkins plugin
•A simple solution until AWX

What’s Cool
• All the scripts and recipe are
Versioned in repo
• All the scripts and recipes are
fetched from repos before
execution
• Inventory files are kept in repo
• Application Manifest
• used to check if the
infrastructure can run
application
• Describe the application in
human language

28.
What’s uncool
• Fight Luddites
• Rundeck GUI
• No miracle for rollback
process
• No nice Ansible output in
Rundeck Console

29.
WHAT’S Next?
•AWX ?
•Integration of new
applications
•Deployment portal
•Create a service
catalog
•provision Vms / Env

Conclusion
• POC is in production,
• The main thing is a question of
culture
• Start by small projects with a
solid devops team,
• Be humble,
• You will need Time,
• You must have convictions,
• You will need perseverance
