我在WSL2上使用了minikube。我部署了一个简单的烧瓶应用程序映像并编写了一个LoadBalancer来公开服务。

我的问题是，如何修改服务清单以获得与公开相同的结果？

以下是更多详细信息。

烧瓶应用程序部署yaml。

rss. yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: esg
spec:
  selector:
    matchLabels:
      app: rss
  replicas: 3
  template:
    metadata:
      labels:
        app: rss
    spec: 
      containers:
      - name: rss
        image: "idioluck/00esg_rss:v01"
        ports:
        - containerPort: 5000

服务yaml（我也尝试了nodeport和loadbalanacer。）

rss_lb. yaml

apiVersion: v1
kind: Service
metadata:
  name: esg-lb
spec:
  type: NodePort # LoadBalancer
  selector:
    app: rss  
  ports:
  - protocol: TCP
    port: 8080 
    targetPort: 5000

kubectl命令是

sjw@DESKTOP-MFPNHRC:~/esg_kube/kubesvc/rss$ kubectl apply -f rss.yaml
deployment.apps/esg created
sjw@DESKTOP-MFPNHRC:~/esg_kube/kubesvc/rss$ kubectl apply -f rss_lb.yaml
service/esg-lb created
sjw@DESKTOP-MFPNHRC:~/esg_kube/kubesvc/rss$ kubectl get pods
NAME                  READY   STATUS    RESTARTS   AGE

esg-757f659b4-4wd2w   1/1     Running   0          13s
esg-757f659b4-sf5q6   1/1     Running   0          13s
sjw@DESKTOP-MFPNHRC:~/esg_kube/kubesvc/rss$ kubectl get all
NAME                      READY   STATUS    RESTARTS   AGE

service/kubernetes   ClusterIP      10.96.0.1       <none>        443/TCP          23h

NAME                  READY   UP-TO-DATE   AVAILABLE   AGE

replicaset.apps/esg-757f659b4   3         3         3       16s

外部IP正在等待。所以我删除loabdbalancer并使用暴露

sjw@DESKTOP-MFPNHRC:~/esg_kube/kubesvc/rss$ kubectl expose deployment esg --type=LoadBalancer --port=8080
service/esg exposed
sjw@DESKTOP-MFPNHRC:~/esg_kube/kubesvc/rss$ kubectl get svc
NAME         TYPE           CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
esg          LoadBalancer   10.99.208.98   127.0.0.1     8080:30929/TCP   46s
kubernetes   ClusterIP      10.96.0.1      <none>        443/TCP          23h

服务已成功暴露。且服务为负载均衡器。
