將exec-opt native.cgroupdriver更改爲「cgroupfs」時，docker無法正確運行？

Question

my os version : centos7.3 
kenerl version : 3.10.0-514.16.1.el7.x86_64 
docker version : 1.12.6 

在將systemd中的選項「--exec-opt native.cgroupdriver」更改爲cgroupfs後，我修改了配置文件「/lib/systemd/system/docker.service」。我發現碼頭不能運行任何圖像！

[root@surenode2 system]# cat /lib/systemd/system/docker.service |grep cgroup 
      --exec-opt native.cgroupdriver=cgroupfs \ 
[root@surenode2 system]# docker images | grep mysql 
docker.io/mysql  latest    e799c7f9ae9c  3 weeks ago   407.3 MB 
[root@surenode2 system]# docker run -p 3307:3307 -e MYSQL_ROOT_PASSWORD=123456 -d mysql 
3395c8d505d3fc20d39e25c510a090649f9f447bce985028ea7274e79183d077 
/usr/bin/docker-current: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"process_linux.go:334: running prestart hook 1 caused \\\"error running hook: exit status 1, stdout: , stderr: \\\"\"\n". 

而且，如果我改變的exec-OPT native.cgroupdriver到systemd，多克爾可以運行任何圖片..

泊塢1.12.6（ 「社區版」）是EOL並且不再支持;
我們可以安裝最新的碼頭版本參考'https://docs.docker.com/engine/installation/linux/centos/'。
當使用最新的碼頭版本時，這個問題不再重現！
