     iptables for network policies, and BGP for ods L3 networking (with optionally BGP peering with out-of-cluster BGP peers).
     It can also optionally advertise routes to Kubernetes cluster Pods CIDRs, ClusterIPs, ExternalIPs and LoadBalancerIPs.

 option to leverage built-in cloud provider networking instead.

 If no external loadbalancer is used, Calico eBPF can also use the localhost loadbalancer option. We are able to do so only if you use the same port for the localhost apiserver loadbalancer and the kube-apiserver. In this case Calico Automatic Host Endpoints need to be enabled to allow services like `coredns` and `metrics-server` to communicate with the kubernetes host endpoint.

+[scheduler-plugins](https://github.com/kubernetes-sigs/scheduler-plugins) is out-of-tree scheduler plugins based on the [scheduler framework](https://kubernetes.io/docs/concepts/scheduling-eviction/scheduling-framework/).
+
+The kube-scheduler binary includes a list of plugins:

+- [CapacityScheduling](https://github.com/kubernetes-sigs/scheduler-plugins/tree/master/pkg/capacityscheduling) [Beta]
+- [CoScheduling](https://github.com/kubernetes-sigs/scheduler-plugins/tree/master/pkg/coscheduling) [Beta]

+- [QualityOfService](https://github.com/kubernetes-sigs/scheduler-plugins/blob/master/pkg/qos/README.md) [Sample]
+
+Currently, we use [helm chart](https://github.com/kubernetes-sigs/scheduler-plugins/blob/master/manifests/install/charts/as-a-second-scheduler/README.md#installing-the-chart) to install the scheduler plugins, so that a second scheduler would be created and running. **Note that running multi-scheduler will inevitably encounter resource conflicts when the cluster is short of resources**.
+
+## Compatibility Matrix
+
+There are requirements for the version of Kubernetes, please see [Compatibility Matrix
+](https://github.com/kubernetes-sigs/scheduler-plugins/tree/master?tab=readme-ov-file#compatibility-matrix). It deserves our attention.
+
+| Scheduler Plugins | Compiled With K8s Version |
+| ----------------- | ------------------------- |
+| v0.28.9           | v1.28.9                   |
+| v0.27.8           | v1.27.8                   |
+
+## Turning it on
+
+  The `scheduler_plugins_enabled` option is used to enable the installation of scheduler plugins.
+
+  You can enable or disable some plugins by setting the `scheduler_plugins_enabled_plugins` or `scheduler_plugins_disabled_plugins` option. They must be in the list we mentioned above.
+
+  In addition, to use custom plugin configuration, set a value for `scheduler_plugins_plugin_config` option.
+
+  For example, for Coscheduling plugin, you want to customize the permit waiting timeout to 10 seconds:
+
+  ```yaml
+  scheduler_plugins_plugin_config:
+    - name: Coscheduling
+      args:
+        permitWaitingTimeSeconds: 10 # default is 60
+  ```
+
+## Leverage plugin
+
+  Once the plugin is installed, we can apply CRs into cluster. For example, if using `CoScheduling`, we can apply the CR and test the deployment in the [example](https://github.com/kubernetes-sigs/scheduler-plugins/blob/master/doc/install.md#test-coscheduling).
