Yeah, thanks for sharing your experiences on that.
Unfortunately our egress costs would likely be significant.
I am honestly anxious to get my employer started on the path to k8s, but until the tooling reduces the hours required to maintain it successfully, Swarm seems like the superior solution if you are locked in on a non-GKE/Azure Container Service provider.
I have heard good things about Kops helping setup/enable production-stable orchestration, but they are not ready yet for Digital Ocean either, although I think it is on the list™.
