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

Deployment Workflow

Get Artifact from Nexus

Deployment request

Pull recipes, inventory, manifest from SVN repos

Check nodes with application manifest

Update nodes

Deploy simultaneously on nodes

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

27

What’s uncool• Fight Luddites

• Rundeck GUI

• No miracle for rollback process

• No nice Ansible output in Rundeck Console

28

WHAT’S Next?

•AWX ?

•Integration of new applications

•Deployment portal

•Create a service catalog

•provision Vms / Env

29

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
