docker 服务不正常

[root@controller03 ~]# docker exec -it keystone bash

rpc error: code = 2 desc = oci runtime error: exec failed: process_linux.go:75: starting setns process caused "fork/exec /proc/self/exe: no such file or directory"[root@controller03 ~]# docker exec -it glance_api bashunable to find user glance: no matching entries in passwd file[root@controller03 ~]# docker exec -it -u 0 glance_api bashrpc error: code = 2 desc = oci runtime error: exec failed: process_linux.go:75: starting setns process caused "fork/exec /proc/self/exe: no such file or directory"

or

对容器内容做下修改，然后docker restart xxxx，重启失败。成功的操作方法：docker stop xxxx，docker start xxxx。

以上错误信息，建议重启docker服务：

sudo service docker restartsystemctl restart docker
