Question

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

在将systemd中的“--exec-opt native.cgroupdriver”选项更改为cgroupfs后，我修改了配置文件“/lib/systemd/system/docker.service”。我发现docker无法运行任何图像！

[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

/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，如果我将exec-opt native.cgroupdriver更改为systemd，Docker可以运行任何图像..

Docker 1.12.6（＆＃34;社区版＆＃34;）已获得EOL且不再受支持;
我们可以安装最新的泊坞广告版本，参考＆＃39; https://docs.docker.com/engine/installation/linux/centos/＆＃39; 使用最新的泊坞窗版本时，此问题不再重现！
