Question

我可以通过运行获取服务

$ kubectl get service <service-name> --namespace <namespace name>

NAME          TYPE           CLUSTER-IP  EXTERNAL-IP  PORT(S)       AGE
service name  LoadBalancer   *********   *********    port numbers  16h

这是我在Kubernetes上运行的服务，但是我无法通过公共IP访问它。以下是我添加的服务和部署文件。我正在使用azre devops构建容器映像并将其释放到azure容器注册表。正如您在服务描述中看到的那样，我获得了外部IP和群集IP，但是当我在浏览器中尝试使用此IP或使用curl时，我没有任何响应。 `

Answer 1

显然标签和选择器不匹配：

服务选择器

"selector": {
      "run": "profile-management-service"

带有部署标签

"labels": {
      "run": "deployment-name"
    },

还要检查服务的 targetPort 值，它应与部署的 containerPort 相匹配

Answer 2

您需要在部署中添加readinessProbe和livenessProbe，然后检查防火墙是否所有规则正确。
