kubernetes pod 端口暴露/转发

Question

我正在尝试在 pod 上公开一个端口 8080，这样我就可以直接从服务器获取 wget。使用端口转发一切正常(kubectl --namespace jenkins port-forward pods/jenkins-6f8b486759-6vwkj 9000:8080)，我能够连接到 127.0.0.1:9000

但是当我尝试避免端口转发并永久打开端口时(kubectl expose deployment jenkins --type=LoadBalancer -njenkins):我在 svc 中看到它(kubectl describe svc jenkins -njenkins):

Name:                     jenkins
Namespace:                jenkins
Labels:                   <none>
Annotations:              <none>
Selector:                 app=jenkins
Type:                     LoadBalancer
IP Families:              <none>
IP:                       10.111.244.192
IPs:                      10.111.244.192
Port:                     port-1  8080/TCP
TargetPort:               8080/TCP
NodePort:                 port-1  31461/TCP
Endpoints:                172.17.0.2:8080
Port:                     port-2  50000/TCP
TargetPort:               50000/TCP
NodePort:                 port-2  30578/TCP
Endpoints:                172.17.0.2:50000
Session Affinity:         None
External Traffic Policy:  Cluster
Events:                   <none>

但端口仍然没有启动，netstat 没有显示任何内容。应该如何正确完成？

使用 minikube 版本:v1.20.0，pod yaml 以防万一:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: jenkins
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jenkins
  template:
    metadata:
      labels:
        app: jenkins
    spec:
      securityContext:

      containers:
      - name: jenkins
        image: jenkins/jenkins:lts

        ports:
          - name: http-port
            containerPort: 8080
            hostPort: 8080
          - name: jnlp-port
            containerPort: 50000
        volumeMounts:
          - name: task-pv-storage
            mountPath: /var/jenkins_home
      volumes:
        - name: task-pv-storage
          persistentVolumeClaim:
            claimName: task-pv-claim

问题出在 minikube 本身 - 在检查 kubectl get events --all-namespaces 时发现了它，发生了一些奇怪的事情，看起来内部代理组件已损坏。
