记录一次docker overlay网络问题处理

重启docker服务后报错:
docker: Error response from daemon: network sandbox join failed: could not get network sandbox (oper true): failed get network namespace "": no such file or directory.

处理方法:
1.修改docker.service
vim /lib/systemd/system/docker.service
先备份然后再移除文件中添加的 cluster-store 和 cluster-advertise .

2.然后重启服务.
systemctl daemon-reload
systemctl restart docker

3.修改docker.service
vim /lib/systemd/system/docker.service
把之前删除的备份cluster-store 和 cluster-advertise重新添加的

4.然后重启服务.
systemctl daemon-reload
systemctl restart docker

5.done
