Kubernetes 错误：- 服务器没有资源类型"logs"

Question

我在尝试部署kubernetes资源时出错，如下所示：

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

Kuectl的官方文档涵盖了Kubectl语法，描述了命令操作，并提供了常见示例。

logskubectl logs POD [-c CONTAINER] [--follow] [flags]打印pod中容器的日志。

您可以随时使用以下命令检查kubectl的命令(以及语法示例(：

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

等等

在这种情况下，需要运行

kubectl logs postfix-bdc88887f-4bp8q

希望这能解释它，并让我们深入了解在哪里可以获得更多信息。

Answer 2

Logs不是kubernetes中的资源，因此要获取pod的日志，不应在命令中指定get，如下例所示。

kubectl logs postfix-bdc88887f-4bp8q
