1. 报 code = Unknown desc = failed to get sandbox ip: check network namespace closed: remove netns: unlinkat /var/run/netns/cni-2502ee8a-9f06-2a44-66c6-59e2a7a277f9: device or resource busy

• 解决方案: see code = Unknown desc = failed to get sandbox ip: check network namespace closed: remove netns: unlinkat /var/run/netns/cni-2502ee8a-9f06-2a44-66c6-59e2a7a277f9: device or resource busy

参考 https://github.com/TimeBye/kubeadm-ha/issues/85

处理方法：

echo 1 > /proc/sys/fs/may_detach_mounts
或者
sysctl -w fs.may_detach_mounts=1

建议：
部署过程中追加 内核参数： fs.may_detach_mounts=1
