docker 个人遇到问题日志记录

system: openSUSE Leap 42.3

在openSUSE中可直接运行" sudo zypper in docker"进行安装docker-ce

wakasann@linux-2ywt:~> docker images
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

找资料，说是 docker服务没有启动

sudo service docker start

参考: 执行docker ps命令，出现 "Cannot connect to the Docker daemon at unix:///var/run/docker.sock. ..."问题
