Supporting Kubernetes is good, but how long for?
Whilst Kubernetes is very cool and there are indeed a load of companies getting interested in it, there's a bit of a looming problem that'll start hitting enterprises using it in the not too distant future... Support Lifecycle.
Docker CE has a 4 month support window, EE (which you have to pay for) has a whole year!. Kubernetes has a three release support policy, and as there's one release every 3 months, companies will be getting at most 9 months of support.
For fast moving start-ups this is (possibly) fine, but for enterprises who are used to 5-10 year support policies, I think it'll come as a rude awakening.
