Thanks again, Tim. With your pointer, I was able to narrow it down and follow a thread of GitHub issues that led me to the root cause:
https://github.com/kubernetes/kubernetes/issues/40182 Long story short, a change in Docker 1.13 sets the default policy for iptables' FORWARD chain to DROP, which causes the problem I was having. Even though I downgraded Docker to 1.12 during my setup, the fact that 1.13+ was installed in HypriotOS by default means that Docker had already done its damage to iptables, and it did not reverse what it did when downgrading it. I look forward to using rkt as the container runtime in the near future so I don't have to deal with the insanity of Docker anymore. :} Jimmy -- You received this message because you are subscribed to the Google Groups "Kubernetes user discussion and Q&A" group.
