Spotifier here. For the record, I hate puppet with the fiery intensity of a thousand suns. It&#x27;s also pretty hard to magically make go away. I could probably do a whole talk on why puppet is difficult to kill, it&#x27;s the kudzu of config management. <i>I think it is the worst.</i><p>We&#x27;ve got our warts and a pile of tech debt, and I wouldn&#x27;t want anyone to think otherwise.  Containers are a part of a long-term strategy to get away from puppet and onto more idempotent units of deployment, and move a lot of what is considered to be &quot;configuration&quot; back into the build process where it belongs.
