kubernetes - kubelet.service:主进程已退出，代码=已退出，状态= 255/n/a

Question

我正在按照以下说明进行测试群集:
https://kubernetes.io/docs/getting-started-guides/fedora/fedora_manual_config/
和

https://kubernetes.io/docs/getting-started-guides/fedora/flannel_multi_node_cluster/
不幸的是，当我检查我的节点时，会发生以下情况:

kubectl get no
NAME                        STATUS     ROLES     AGE       VERSION
pccshost2.lan.proficom.de   NotReady   <none>    19h       v1.10.3
pccshost3.lan.proficom.de   NotReady   <none>    19h       v1.10.3

据我所知，这个问题与主节点上的kubelet.service不起作用有关:

systemctl status kubelet.service

有人可以提供建议吗，我该如何解决？谢谢

Answer 1

解决了kubelet向其中添加--fail-swap-on=false"的问题
Kubelet配置文件中的KUBELET_ARGS=。但是节点的问题仍然存在-状态未就绪
