我是k8的新手,所以我的某些术语可能不正确。但基本上,我正在尝试部署一个简单的Web api:在n个pod前面有一个负载均衡器(现在,n = 1)。
但是,当我尝试访问负载平衡器的IP地址时,它没有显示我的Web应用程序。当我运行kubectl get部署时,我得到了:
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
tl-api 1 1 1 0 4m
这是我的YAML文件。让我知道是否有什么情况–我对此很陌生!

答案 0 :(得分:2)
您的问题是容器映像tlk8s.azurecr.io/devicecloudwebapi:v1
在私有容器注册表中。请查看以下命令底部的事件:
$ kubectl describe po -l=app=tl-api
Kubernetes官方文档描述了如何解决此问题,请参阅Pull an Image from a Private Registry,本质上是:
kubectl create secret docker-registry
spec.imagePullSecrets
键下在部署中使用它
