I'm back at Rejekts for the last couple of afternoon talks. I'm about to learn about the Wrong Way to Reconcile by Scott Nichols (@n3wscott.com), which I'm sure will be very informative given that I have at this point written several reconcilers and I'm sure they're all wrong. #kubecon #rejekts

Every CRD needs .status.conditions, which must have lastTransitionTime, status, type, and observedGeneration. Condition.type must be "ready" or "succeeded".

We have examples of declarative APIs all over the place. Fav example is the thermostat: "Dear thermostat, I declare that I would like my room to be 68 degrees", and the thermostat monitors the environment and adjusts the temperature.

CRD generations only change if the _spec_ changes -- metadata or status changes bump the resource version, but not the generation.

Once you've made a modification to your object in the reconcile loop, you should probably just bail at that point.
