Question

目前我的机器上安装了docker 1.7.1，我想通过以下步骤将其升级到最新版本。

1. service docker stop
2. wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O /usr/bin/docker
3. service docker start

但是当我执行第三步时，我遇到了问题。

[root@xxx ~]# service docker start
Redirecting to /bin/systemctl start  docker.service
Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details.

Then I execute the two command to get more info like below

[root@xxxxx ~]# systemctl status docker.service

Answer 1

issue 17566

中提到了这一点

1.9 rpms现在捆绑了一个selinux政策：http://yum.dockerproject.org/repo/testing/centos/7/Packages/


使用http://yum.dockerproject.org/repo/testing/centos/7/Packages/创建了docker repo并成功安装并启动了最新的docker-engine。

注意：您也可以使用http://yum.dockerproject.org/repo/main/centos/7/Packages/，其中包括CentOS的最新1.9.1官方软件包。

rpm -qa | grep docker
yum install -y http://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.9.1-1.el7.centos.x86_64.rpm

Answer 2

RHEL将其自己版本的Docker守护程序与--add-registry等其他命令行选项捆绑在一起。另请参阅https://access.redhat.com/articles/1354823。

RHEL上的systemd脚本是围绕RHEL Docker守护程序及其附加选项建模的。如果直接从Docker.com下载Docker版本，则会出现启动问题。您需要修改systemd脚本，或者需要坚持使用官方RHEL和CentOS升级渠道。
