k8s：服务不变但未列出

Question

我正在尝试在 kubernetes 上创建服务，但虽然未打印任何错误，但我无法列出该服务；

与 minikube

在本地工作

*$ kubectl get services
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   4h
/home/pkara/Workspace/gitlab/my-minikube
*$ kubectl apply -f mydb.yaml 
service/mydatabase unchanged
/home/pkara/Workspace/gitlab/my-minikube
*$ kubectl get services
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   4h

这是使用的清单：

---

apiVersion: v1
kind: Service
metadata:
  name: mydatabase
  namespace: esa-local-dev
  labels:
    app: mydatabase
spec:
  ports:
  - name: mydatabase-port
    port: 3306
    targetPort: 3306
  selector:
    app: mydatabase
  clusterIP: None

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mydatabase-deployment
  labels:
    app: mydatabase
spec:
  selector:
    matchLabels:
      app: mydatabase
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: mydatabase
    spec:
      containers:
      - name: mysql
        image: mysql:5.7
        env:
        - name: MYSQL_ROOT_PASSWORD
          value: "root"
        - name: MYSQL_DATABASE
          value: "mydatabase"
        - name: MYSQL_USER
          value: "mydatabase"
        - name: MYSQL_PASSWORD
          value: "mydatabase"
        ports:
        - containerPort: 3306
          name: mysql
      restartPolicy: Always

服务是在 esa-local-dev 命名空间上创建的。在你的 yaml 中，你有：

apiVersion: v1
kind: Service
metadata:
  name: mydatabase
  namespace: esa-local-dev
...

您可以通过运行,

查看服务

$ kubectl get services -n esa-local-dev

k8s：服务不变但未列出

k8s: service unchanged but not listed

kubernetes

kubectl
