`master_port
=**29501**` 是配置参数的一部分，通常用于设置 Kubernetes 集群中的 Master 节点上Kube-Scheduler 或 Kubelet 进程监听的服务端口。这个端口是用于协调器节点（Master）与工作节点之间的通信，比如调度决策。
具体来说，在Kubernetes集群中，`master_port` 指定了ServiceAccount Token Webhook (如果启用) 或 API Server Service 的TCP端口。当工作节点上的 pods 请求访问API资源时，会通过这个端口进行身份验证。
示例配置可能出现在 `kube-scheduler` 或 `kubelet` 的启动命令行选项中，如：
```yaml
# kube-scheduler配置
kubectl create -f - <<EOF
apiVersion: v1
kind: ConfigMap
metadata:
name: kube-scheduler-config
data:
scheduler.config: |
apiVersion: kubescheduler.k8s.io/v1beta1
kind: KubeSchedulerConfiguration
masterUrl: https://<master-ip>:29501
---
apiVersion: apps/v1
kind: Deployment
metadata:
name: kube-scheduler
