Introducing Main Feature of OpenYurt: Local Autonomy

  1. How to recover Pod information when the connection to Master is down and Kubelet restarts during that period of time?
  2. When the worker nodes cannot be reached by the control plane for certain period of time, the pods on those nodes will get evicted.
  3. After resumption, the edge nodes and master nodes may need to reconcile their status differences.
  4. The connection may not be bi-directionally available. The edge nodes may connect to intranet with outbound networking configured only. For security reasons, the cloud site control plane may not be able to directly address the edge node.

YurtHub

  1. There is no change to the upstream code. Simple and easy maintenance.
  2. The YurtHub can be used by other node components if they need to leverage the capability of autonomy.
