seems everything going fine,I am confusing, what should I do to fix it? This is my docker version info:
[root@log001 run]# docker version
Client:
Version: 18.09.6
API version: 1.39
Go version: go1.10.8
Git commit: 481bc77156
Built: Sat May 4 02:34:58 2019
OS/Arch: linux/amd64
Experimental: false
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
I have already read this post, it seems not suite my situation.
