We work at Wer liefert was

The Pain with Puppet

  • Execution Order
  • DevOps write the stuff
  • Production Server
  • Change from monolith software to APIs

Infrastructure

Software

The Fun (why we use it)

  • We love yml files (rails!)
  • Requires only sshd and Python
  • Fast, Clear Execution Order
  • Modules for psql, rabbitmq and more

Best Practice - project structure

  • Every rails app own playbook file
  • Every external application own roles file
  • same path on every environment

Best Practice - key management

  • Key Repository
  • CI get triggered by changes and publish all keys
  • Keys as git submodule in your ansible repository

Best Practice - Release Management

  • Test from blank!
  • Test by diff!

Best Practice - Work with DevOps

  • Huge task to transfer puppet to ansible scripts
  • Show them how both can benefit (Continous Delivery)
  • Use .env files for configuration

Vagrant

  • Testing ansible stuff
  • Clean state of development VM?!
  • Performance ?
  • System Ruby :-(

The Pain (with Ansible)

  • Keep servers in sync
  • QA the stuff! (CI integration?)

Thank you!

  • Questions?
