KubeSphere版本信息
v3.2.1 在线安装

问题是什么
按照暴露TCP和UDP服务，编写了tcp-services.yaml

kind: ConfigMap
apiVersion: v1
metadata:
  name: tcp-services
  namespace: kubesphere-controls-system
  annotations:
    kubesphere.io/creator: sunyajie
data:
  '3306': 'cloud-platform-java-dev/mysql:3306'

新增了- '--tcp-services-configmap=kubesphere-controls-system/tcp-services'

kind: Deployment
apiVersion: apps/v1
metadata:
  name: kubesphere-router-cloud-platform-java-dev
  namespace: kubesphere-controls-system
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: kubesphere-router-cloud-platform-java-dev-ingress
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/version: 0.48.1
    helm.sh/chart: ingress-nginx-3.35.0
  annotations:
    deployment.kubernetes.io/revision: '6'
    meta.helm.sh/release-name: kubesphere-router-cloud-platform-java-dev-ingress
    meta.helm.sh/release-namespace: kubesphere-controls-system
    servicemesh.kubesphere.io/enabled: 'false'
spec:
  replicas: 1
  selector:
    matchLabels:
      app.kubernetes.io/component: controller
      app.kubernetes.io/instance: kubesphere-router-cloud-platform-java-dev-ingress
      app.kubernetes.io/name: ingress-nginx
  template:
    metadata:
      creationTimestamp: null
      labels:
        app.kubernetes.io/component: controller
        app.kubernetes.io/instance: kubesphere-router-cloud-platform-java-dev-ingress
        app.kubernetes.io/name: ingress-nginx
      annotations:
        sidecar.istio.io/inject: 'false'
    spec:
      containers:
        - name: controller
          image: 'kubesphere/nginx-ingress-controller:v0.48.1'
          args:
            - /nginx-ingress-controller
            - >-
              --election-id=ingress-controller-leader-kubesphere-router-cloud-platform-java-dev
            - '--ingress-class=nginx'
            - >-
              --configmap=$(POD_NAMESPACE)/kubesphere-router-cloud-platform-java-dev
            - '--watch-namespace=cloud-platform-java-dev'
            - '--tcp-services-configmap=kubesphere-controls-system/tcp-services'
...
...

会马上创建一个新的pod，还未创建完成，新的pod就又被删除了，查看Deployment，发现新增的--tcp-services-configmap=kubesphere-controls-system/tcp-services

就没有了

然后修改IngressController，新增3306端口暴露

kind: Service
apiVersion: v1
metadata:
  name: kubesphere-router-cloud-platform-java-dev
  namespace: kubesphere-controls-system
  labels:
    app.kubernetes.io/component: controller
    app.kubernetes.io/instance: kubesphere-router-cloud-platform-java-dev-ingress
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/version: 0.48.1
    helm.sh/chart: ingress-nginx-3.35.0
spec:
  ports:
    - name: http
      protocol: TCP
      port: 80
      targetPort: http
      nodePort: 32444
    - name: https
      protocol: TCP
      port: 443
      targetPort: https
      nodePort: 30872
    - name: mysql
      protocol: TCP
      port: 3306
      targetPort: 3306

编辑后，会暴露新的端口

但是在外面使用对应的30536端口发现无法访问，telnet也发现30536端口没有打开
