I tried to install docker on my ubuntu 14.04. After Installation I had some issues you can read them here: docker installation issue file not found after installation

Installation is done now but when I run docker ps -a I got this error:

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I thought okay no problem I start it. So I ran /etc/init.d/docker start

Nothing changed. What is the issue in this case?

Thanks in advance

UPDATE

Docker lock sais

  • Do you have any custom kernel? What is your architecture, kernel/docker version and how did you install docker?

3.13 is a quite old kernel. Install latest stable stock kernel (kernel from 3.19 has support for overlay FS). The main blocker is cgroup issue. Cgroups must be available.

Other useful tips: error starting docker daemon on ubuntu 14.04 (Devices cgroup isn't mounted)

I think your docker user is not sudoer; 1. Create the docker group.

sudo groupadd docker

2. Add your user to the docker group.

sudo usermod -aG docker $USER

3. Log out and log back in so that your group membership is re-evaluated. 4. Verify that you can run docker commands without sudo

docker run hello-world
