K8S/Kubernetes

查看pod日志

[root@k8s-master1 ~]# kubectl logs nginx-7cdbd8cdc9-2qrcw

Error from server (Forbidden): Forbidden (user=system:anonymous, verb=get, resource=nodes, subresource=proxy) ( pods/log nginx-7cdbd8cdc9-2qrcw)

如果出现报错这里说明缺少一个默认的绑定集群的角色

定义/opt/kubernetes/cfg/kubelet.config

 追加以下配置

authentication:

  anonymous:

    enabled: true

 

并创建赋予系统集群一个角色

[root@k8s-master1 ~]# kubectl create clusterrolebinding cluster-system-anonymous --clusterrole=cluster-admin --user=system:anonymous

 再次查看pod日志，成功输出

[root@k8s-master1 ~]# kubectl logs nginx-7cdbd8cdc9-2qrcw
