Docker CE only running in a new terminal when dockerd is running in another


(Vivekraj25) #1

Issue type:

Docker CE can not be connected to docker daemon

OS Version/build

On Linode cloud(through ssh)

Ubuntu 16.04 LTS

App version

Docker version 18.09.0, build 4d60db4(Docker CE)

Steps to reproduce

a)Followed the steps on this link: https://docs.docker.com/install/

b)Tested docker by running sudo docker run hello-world

Hi Champs,

I am new to the docker and I tried to install docker ce through the link https://docs.docker.com/install
It got it installed but when I tried to test the docker by running the hello-world command as mentioned,it gives me the following error:

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See ‘docker run --help’.

However,when I open another terminal and run dockerd command manually and try from yet another terminal,it works(until I have the other terminal in which I run the dockerd command is open.

The output of dockerd command shows the following output and precisely some errors:

How can I fix the issue,what am I missing because of which the docker is not running by default.

Thankyou,
Vivek

PS:The same steps followed on my local machine Ubuntu 16.04 lts runs succesfully.
