Easypack: Kubernetes 1.17.2 设定选项更新：Kubelet

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   Ready4m19s   v1.17.2   192.168.163.131CentOS 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
