kubernetes - Kubernetes 负载均衡器服务器连接被拒绝：默认 80 端口正在工作

Question

部署 Spring 微服务后，Kubernetes 中的负载均衡器未连接到 Google Cloud Platform 中提到的端口。

我们需要更改任何防火墙设置以连接到已部署的服务吗？

这很可能是您的 Kubernetes 服务和/或部署的问题。ServiceGKE 将自动配置映射到资源的端口所需的防火墙规则。

确保您已port 80在您的上公开Service并将其映射到您Deployment的上的有效端口Pods

下面是一个使用DeploymentandService暴露 nginx pod 的示例：

部署.yaml： apiVersion: apps/v1 # API Version of this Object kind: Deployment # This Object Type metadata: # Allows you to specify custom metadata name: nginx # Specifies the name of this object spec: # The official specification matching object type schema selector: # Label selector for pods matchLabels: # Must match these label(s) app: nginx # Custom label with value template: # Template describes the pods that are created metadata: # Standard objects metadata labels: # Labels used to group/categorize objects app: nginx # The name of this template spec: # Specification of the desired behaviour of this pod containers: # List of containers belonging to this pod (cannot be changed/updated) - name: nginx # Name of this container image: nginx # Docker image used for this container ports: # Port mapping(s) - containerPort: 80 # Number of port to expose on this pods ip

服务.yaml： apiVersion: v1 kind: Service metadata: name: nginx labels: app: nginx spec: type: LoadBalancer selector: app: nginx ports: - name: http port: 80 targetPort: 80

要查看正在映射的 IP 地址（和端口），您可以运行： kubectl get services和kubectl describe pod <your pod name>`

如果您仍然遇到问题，请提供上述两个kubectl命令的输出。

祝你好运！
