I am trying to learn about "Docker" in ubuntu 15.04.
When I give any command using docker like "docker run image", it get the following error:
FATA Post http:///var/run/docker.sock/v1.17/containers/create: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?
I don't understand what does it mean.
