Chef

• Chef-Server as central hub

41. Camp Mallorca

Chef: Cookbooks
• Dependencies between cookbooks
• e.g. TYPO3 cookbook uses Apache2
cookbook to create vHosts
• Notification triggers actions
(config file changes -> service restarts)

42. Camp Mallorca

Chef: Architecture
• Chef-client runs on every server
• Communicate with our Chef-Server
• Client registers once at the Chef-Server
• Authenticated data exchange (through certificates)
• Chef-Client retrieves roles, cookbooks and attributes
• Chef-Client executes the Ruby code and configures the Linux system

43. Camp Mallorca
14. - 16. September 2012
Chef: Attributes
• Per-host attributes are saved in Chef Server
• Examples for attributes
• Host name for Apache vHost
• Datacenter-specific smarthost for postfix
• Password of the MySQL user

• `vagrant up` creates/starts VM
• Configures the VM as defined in Chef
• Great combination!

Chef: Cookbook Sharing
• Healthy community writing cookbooks
• Our cookbooks open-sourced
