更新后 Docker 守护进程无法启动

Question

昨晚我的 docker 守护程序更新到版本 18.09.0-ce-tp0，构建 4bb0619，从那时起它无法启动。我以前运行 docker 没有任何问题。操作系统:CentOS Linux 版本 7.5.1804(核心)错误:

为了清楚起见，我从 systemctl start docker(或 docker.service)开始，例如docker ps 返回 Cannot connect to the Docker daemon at unix:///var/run/docker.sock。 docker 守护进程是否正在运行？

有什么线索吗？

我通过将 docker 从版本 18.06.1-ce, build e68fc7a 更新到版本 18.09.0~ce~0.4.tp4-0~ubuntu 遇到了同样的问题.我的解决方案是:

1) 移除docker-ce:

sudo apt-get remove docker-ce

2) 移除依赖包:

sudo apt-get autoremove

3)检查docker是否被移除(应该看到docker command not found):

docker -v

4)安装低版本docker:

sudo apt-get install docker-ce=18.06.1~ce~3-0~ubuntu

5) 检查docker服务是否运行:

sudo service docker status

它对我有用。希望以上解决方案对您有所帮助。
