Downstream clusters flapping between available and unavailable state
This document (000020416) is provided subject to the disclaimer at the end of this document.
Management cluster K8S version: 1.21.5
Rancher Pod logs show errors like the below;
Failed to connect to peer wss://x.x.x.x/v3/connect [local ID=y.y.y.y]: websocket: bad handshake
A workaround until Rancher upgarde is to reduce the Rancher deployment replicas to one.
As of Kubernetes version v1.21, service account tokens are pod-specific, and are invalidated when the pod is deleted, which is why Rancher is unable to use it and thus unable to reach other Rancher replica instances via web-socket.
