DevOps Cardiff - Puppet vs Chef vs Ansible

  1. 1. Puppet vs Chef vs Ansible Mark Phillips
  2. 2. About Me • Linux tinkerer since 1992 • Automating stuff since 1993 • “Done time” in small organisations through to Investment Banks • I’m lazy
  3. 3. Here I talked about not wanting to do the 'heavy lifting' myself, what I wanted to do was ...
  4. 4. ... have the computers do it for me. In other words, automate stuff.
  5. 5. (no, this is all just my opinion)
  6. 6. Demo Infrastructure
  7. 7. Chef http://youtu.be/miO00M4vPok
  8. 8. Puppet http://youtu.be/miO00M4vPok?t=5m55s
  9. 9. Ansible http://youtu.be/miO00M4vPok?t=8m44s
  10. 10. Points of note • Chef is big and ugly • Puppet is a bit better • Both have complexity you don’t need
  11. 11. http://www.ansible.com/get-started “I wrote Ansible because none of the existing tools fit my brain. I wanted a tool that I could not use for 6 months, come back later, and still remember how it worked.” ! Michael DeHaan! Ansible project founder
  12. 12. Quote from a wise man
  13. 13. The Times newspaper, on a Saturday, has an article titled "What I've learnt". The previous quote was from an interview with Matt LeBlanc
  14. 14. https://www.vitsoe.com/gb/about/good-design Good design is as little design as possible! Less, but better – because it concentrates on the essential aspects, and the products are not burdened with non-essentials. Back to purity, back to simplicity
  15. 15. At the DevOps Cardiff meet I had an anecdote that preceded the next slide. I've put this extra slide in before uploading the presentation with that short anecdote. ! A while back a mate with a startup had asked me about CM software, and if he should use Chef. "NO!" came my emphatic answer. "Take a look at Ansible". A few days past, then I got a text message from him. ! Autocorrect on iPhones? You know how ducking annoying that shiv can be? Well, sometimes it actually gets things right...
