Why are there three klusterlet pods in a managed cluster?(problem)

[Willy1999927]

In the cluster I have with one master and two workers, why are there three klusterlet pods used to pull the configuration and execute it? Do you have a complete architecture diagram?

xxx@xxx:/home/cdlab# kubectl get pods -n open-cluster-management -o wide
NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES
klusterlet-67d4cdc69-5mms5 1/1 Running 16 (16h ago) 29d 10.244.43.1 worker1
klusterlet-67d4cdc69-bk49j 1/1 Running 4 (24h ago) 29d 10.244.43.2 wroker1
klusterlet-67d4cdc69-x75hk 1/1 Running 12 (16h ago) 29d 10.244.70.132 worker2

The number or replica is decided here https://github.com/open-cluster-management-io/ocm/blob/main/pkg/operator/helpers/helpers.go#L435. The is mainly for the HA case, and ensure the agent keeps on running during rolling upgrade.
