Known Issues

A known issue with Container Engine's IP Rotation feature can cause it to break Kubernetes features that depend on the proxy endpoint (such as kubectl exec, kubectl logs), as well as cluster metrics exports into Stackdriver. This issue only affects your cluster if you ran CompleteIPRotation, and have also disabled the default SSH firewall rule for cluster nodes. There is a simple manual fix; see IP Rotation known issues for details.
