we’re currently evaluating rancher 2.x with kubernetes on vSphere in our company and had an power outage recently.
The expected behaviour for rancher was, that the k8s cluster starts and is again available in rancher, but this isn’t the case. After the nodes rebooted, they got different ip addresses assigned by our dhcp-server and reported back to rancher with their new addresses. Rancher instead, didn’t recognized the nodes and kept searching for them at their old addresses. Is this an expected behaviour?
