Question

请帮助。我正在尝试将Web API部署到Azure ACS Kubernetes群集，这是在VSTS中创建的简单Web API，其结果应为： { "value1", "value2" } 。

我打算将该类型设置为Cluster-IP，但是我想先测试并访问它，这就是LoadBalancer的原因，吊舱正在运行并且没有重新启动（我认为很好）。

我要遵循的指南是：Running Web API using Docker and Kubernetes

NAME                TYPE           CLUSTER-IP     EXTERNAL-IP    PORT(S)            AGE
kubernetes          ClusterIP      10.0.0.1       <none>         443/TCP            3d
sampleapi-service   LoadBalancer   10.0.238.155   102.51.223.6      80:31676/TCP   1h

当我尝试浏览IP 102.51.223.6/api/values时说：

“无法访问此网站”

service.yaml

     # Port to forwards inside the pod
     targetPort: 80
     # Port accessible oustide the cluster
     #nodePort: 80
  type: LoadBalancer

deployment.yml

Answer 1

在我看来，您的服务未设置为容器上的端口。您已将operator.注释掉。因此，该服务可在端口80上访问，但该服务不知道该端口上的pod的目标。

无法访问在Azure ACS Kubernetes群集中部署的Web API
