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
