A Service is exposed on each node's IP address at a static port (NodePort). When you create a NodePort Service, Kubernetes automatically allocates an internal IP address
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE example-app NodePort 10.0.0.100 <none> 80:32456/TCP 5m 其中,NodePort为32456。 现在,我们可以使用集群中任何一个节点的公共IP地址和端口32456来访问该Service。例如,如果节点的公共IP地址为192.168.1.100,则可以使用以下URL访问该Service: 代码语言:javascript 代码...
以下是获取特定服务(例如 example-service)的 NodePort 端口号的完整命令示例: bash kubectl get svc example-service -o jsonpath='{.spec.ports[0].nodePort}' 这个命令会输出 example-service 服务的 NodePort 端口号,例如 30001。 通过这些步骤,你就可以在 Kubernetes 集群中获取到所需服务的 NodePort 端口号...

Use NodePort Services to expose applications,Container Service for Kubernetes:In Kubernetes, a Service is an abstraction to expose an application running on a set of pods as a network service. This topic uses an NGINX stateless application as an example
kubectl apply -f example-service.yaml ``` ### 步骤3:获取Service的NodePort端口 您可以使用以下命令来查看Service的NodePort端口: ```bash kubectl get service example-service ``` ### 步骤4:在浏览器中访问NodePort端口 最后,您可以在浏览器中使用NodePort端口来访问您的服务。假设NodePort端口为30000,那么您...

为了将运行在Kubernetes集群内部 Pod 上的应用程序投入使用,需要启用 K8S 集群上的服务(Service):NodePort 或 ClusterIP,然后再经过外部 LoadBalancer 或 Ingress 功能,将服务发布为可被集群外部客户端访问的 IP 地址或者 FQDN(如:web.example.com )。
kind: Service metadata: name: backend spec: selector: app: backend ports: - name: http port: 80 targetPort: 8080 In this example, we define a service namedbackendwith a selector that targets pods labeled withapp: backend.The service exposes port80, which is the port used by clients to...
kind: Service metadata: name: example-service spec: type: NodePort ports: - port: 80 targetPort: 80 nodePort: 30001 selector: app: example ``` 在上述示例中,我们创建了一个名为`example-service`的Service,将其类型设置为NodePort,并指定端口为80,NodePort为30001。保存为`example-service.yaml`文件。
