The Kubernetes controller manager runs several controllers that manage the state of various Kubernetes objects. Some of the key controllers include:
- Replication Controller: Ensures that a specified number of pod replicas are running at any given time.
- Node Controller: Manages the state of nodes in the cluster, monitoring their health and status.
- Job Controller: Manages the execution of jobs, ensuring that a specified number of pods complete successfully.
- DaemonSet Controller: Ensures that a copy of a pod runs on every node in the cluster.
- Endpoint Controller: Populates the Endpoints object, which is used to track the network endpoints for services.
These controllers work together to maintain the desired state of the cluster and its resources.
