Epic Goal
The leader election of the klusterlet-agent is disabled on the single node managed cluster to speed up the restart procedure. While it might cause that two pods with different configuration, such as images or bootstrap config, running at the same time. Some unexpected behavior happens in this situation, including
- the agent switch back to the previous hub;
- Too many CSRs are created;
To fix those issues, it is necessary to enable the leader election of the klusterlet-agent on all managed cluster, including the single node managed cluster.
