docker error : dial unix /var/run/docker.sock: no such file or directory

I saw the following errors.

root@ubuntu:~# docker.io version Client version: 0.9.1 Go version (client): go1.2.1 Git commit (client): 3600720 2014/06/15 18:54:12 dial unix /var/run/docker.sock: no such file or directory root@ubuntu:~# tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 14.04 LTS"

In my case, I was able to fix this by adding “-H unix:///var/run/docker.sock”

edit /etc/default/docker.io file.

root@ubuntu:~# grep -i ^docker_opts  /etc/default/docker.io DOCKER_OPTS="-dns 8.8.8.8 -dns 8.8.4.4 -H tcp://192.168.11.100:4243 -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock"

restart docker.
