Question

当我安装docker并运行service docker start时，我收到了此消息：

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

当我跑journalctl -xe时，我收到了这条消息：

感谢我的朋友们

Answer 1

Docker版本1.13.1

CentOS Linux版本7.2.1511（核心）

bash # cat  /etc/sysconfig/docker-storage

DOCKER_STORAGE_OPTIONS =＆＃34; - 存储驱动程序devicemapper＆＃34;

bash # cat  /etc/sysconfig/docker-storage-setup

STORAGE_DRIVER = devicemapper

Answer 2

根据compatibility matrix docker-1.13，CentOS仅支持devicemapper。

在使用overlay2时默认启动docker尝试类似的问题，解决了降级到docker-1.12的问题。

覆盖图驱动程序不支持SELinux
