Unable to login to docker, TLS-enabled daemon without TLS?

Hi,

I have attempted to install Docker on Ubuntu trusty 14.04.2 following the online guideline.

I get this message when I try to login or type $docker run hello-world:

Post http:///var/run/docker.sock/v1.19/auth:dial unix /var/run/docker.sock: permission denied. Are you trying to connect toa TLS-enabled daemon without TLS?

When I type $sudo service docker start , it says that docker is already running

When checking docker’s version I get this message:
Client version: 1.7.0
Client API version: 1.19
Go version (client): go1.4.2
Git commit (client): 0baf609
OS/Arch (client): linux/amd64
Get http:///var/run/docker.sock/v1.19/version:dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?

Any idea what is the problem?

Appreciate your help!

Hi,

You probably need to add sudo to your commands or add your user to the docker group and then log out/in again.

You can add your user account to the Docker group with:

sudo usermod -aG docker <username>
