Question

尝试按以下方式部署kubernetes资源时出现错误：

suv@Suvankars-MacBook-Pro[8:50:09]:~/thermeon/gke-staging-envs/charts$ helm install --name=postfix postfix 
NAME:   postfix
LAST DEPLOYED: Sun Jul 12 20:50:15 2020
NAMESPACE: default
STATUS: DEPLOYED

RESOURCES:
==> v1/Service
NAME     AGE
postfix  2s

==> v1beta2/Deployment
postfix  2s

==> v1/Pod(related)

NAME                     READY  STATUS             RESTARTS  AGE
postfix-bdc88887f-4bp8q  0/1    ContainerCreating  0         2s


NOTES:
1. Get the application URL by running these commands:
     NOTE: It may take a few minutes for the LoadBalancer IP to be available.
           You can watch the status of by running 'kubectl get svc -w postfix'
  export SERVICE_IP=$(kubectl get svc --namespace default postfix -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
  echo http://$SERVICE_IP:25

Answer 1

Kubectl's Official Documentation涵盖了kubectl语法，描述了命令操作，并提供了常见示例。

logs kubectl logs POD [-c CONTAINER] [--follow] [flags]打印容器中容器的日志。

您始终可以使用以下命令来检查kubectl的命令（和语法示例）：

$ kubectl --help
$ kubectl get --help
$ kubectl logs --help

以此类推。

在这种情况下，需要运行

kubectl logs postfix-bdc88887f-4bp8q

希望能对此进行解释，并深入了解从何处获取更多信息。

Answer 2

日志不是Kubernetes中的资源，因此要获取Pod的日志，您不应在命令中指定get，如下例所示。

kubectl logs postfix-bdc88887f-4bp8q

Kubernetes错误：-服务器没有资源类型“日志”
