看系统日志 cat /var/log/messages 用kubectl 查看日志 # 注意：使用Kubelet describe 查看日志，一定要带上 命名空间，否则会报如下错误 [root@node2 ~]# kubectl describe pod coredns-6c65fc5cbb-8ntpv Error from server (NotFound): pods "coredns-6c65fc5cbb-8ntpv" not found kubectl describe pod kubernetes-dashboard-849cd79b75-s2snt --namespace kube-system kubectl logs -f pods/monitoring-influxdb-fc8f8d5cd-dbs7d -n kube-system kubectl logs --tail 200 -f kube-apiserver -n kube-system |more kubectl logs --tail 200 -f podname 用journalctl查看日志非常管用 journalctl -u kube-scheduler journalctl -xefu kubelet journalctl -u kube-apiserver journalctl -u kubelet |tail journalctl -xe 用docker查看日志 docker logs c36c56e4cfa3 (容器id)
