I am very happy working with Kubernetes in a very small team, I really like the abstraction of the different entities and the declarative ways to configure them.

I think that the learning curve is not that steep if you already had to do the same than with Kubernetes with other alternatives, in my on experience I have been discovering a lot of features that are very helpful not just during production but also during the development environments that were a real pain before.

I am have a lab/cluster/blog running on Kubernetes, I am in charge of this one alone, it is opensource [1], I version everything that goes to the cluster so you can see the evolution of the kubernetes entities, the config, the containers and the code. I started this from scratch and improving it feature to feature, I think that this might be a big factor with my positive experience with Kubernetes.

I wonder if an issue with adopting kubernetes is to try to migrate a big system into kubernetes in a very limited time lapse and trying to push/force features as they were working/handled in the previous approach?
