以目前最新的稳定版本1.17.2，总结一下Kubelet设定选项更新内容。
版本
[root@host131 ansible]# kubectl get node -o wide
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
192.168.163.131 Ready <none> 4m19s v1.17.2 192.168.163.131 <none> CentOS Linux 7 (Core) 3.10.0-957.el7.x86_64 docker://19.3.5
[root@host131 ansible]#
问题与对应
如下选项已过时，删除：
- –event-qps={{ var_kubelet_opt_event_qps }} \
- –kube-api-qps={{ var_kubelet_opt_kpi_qps }} \
- –kube-api-burst={{ var_kubelet_opt_api_brust }} \
- –registry-qps={{ var_kubelet_opt_reg_qps }} \
swap设定：
-
–fail-swap-on=False \
-
错误提示信息如下所示：
Flag --fail-swap-on has been deprecated, This parameter should be set via the config file specified by the Kubelet's --config flag. See https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/ for more information.
- 对应方法
在config指定的配置文件中添加如下内容：
failSwapOn: False
- 重启后确认
[root@host131 k8s]# systemctl status kubelet -l
