Docker: Are you trying to connect to a TLS-enabled daemon without TLS?

On Linux Mint 17.1 x86_64 with kernel 3.13.0-48-generic and OpenSSL version 1.0.1f-1ubuntu2.11; whenever I try to execute any docker command (like

docker login
or
docker run hello-world
), I get the following error:

FATA[0000] Get http:///var/run/docker.sock/v1.18/info: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS?


I have made a group called
docker
using
sudo usermod -aG docker username
, I have tried running the commands both as root and normally, added
$(boot2docker shellinit 2> /dev/null)
to
~/.profile
as instructed here, restarted my PC and reinstalled OpenSSL.

Any idea what am I missing? Can this be a hardware issue?

Answer

You can check if it has started by running the command ps -ef. You can also grep it to docker if you want to reduce the number of results. If its of not running, execute

sudo service docker start

OR if it still doesn't work then

You can refer this link

docker docs

You can run docker run -d or docker run -d & so that you can use the same terminal or even close it if. It will set the value to true, so your container will run in "detached" mode, in the background.

You can also auto start it when your OS starts using update-rc.d servicename defaults or you can also refer to the links below, where you have to give docker as service name and your defaults.

Some more links to refer - auto start, upstart

These are different ways of doing it.
