> Secondly, developing on Kubernetes “sucks” compared to what? Mesos? Docker Swarm?

My thoughts exactly. I feel like most people who complain about these things are just feeling grumpy about the overall experience, and aren't always quite sure where to place the blame.

It takes a lot of introspection to know exactly where a system should be better than it is... "this yaml is too complex", until you start thinking about how you'd do it better, and then you realize all the problems each of the similar approaches have, and that a lot of it was done for a reason, etc.

Or you start comparing k8s to completely different approaches like just rsyncing some files to a remote webserver and SIGHUP'ing it, which is much simpler but has its own host of reliability/testability/reproducability concerns.

I think in reality, people are overwhelmed by what it really takes to adopt best practices (declarative deployment, CI/CD, health checks, service discovery, etc). Practices that have been hard fought and discovered over many years of people trying things and failing. K8S IMO represents the state of the art in a lot of them, but too often people place blame on k8s when what they're really doing is questioning the best practices themselves. Practices that are also shared across k8s's competitors like mesos and docker swarm.
