Answer 1

One way to resolve this would be to first add your user to the docker group by running the following

sudo usermod -aG docker $USER

IMPORTANT: Remember to log out of your system (not just your terminal) and back in for this to take effect!

Answer 2

I think it's because of right of access, you just have to write

sudo docker-compose-deps.yml up

Answer 3

in my case it is because the ubuntu permission,

1. List item

check permission by

docker info 

if they print problem permission, then use

sudo chmod -R 777 /var/run/docker.sock

Answer 4

For me the fix was to install a newer version (1.24) of docker-compose using this article.

The previous version (1.17) was installed from ubuntu's default repository, but after installing a newer version I managed to launch the container. Hope it helps somebody.

Answer 5

I had the same error, after 15 min of debugging. Turns out all it needs is a sudo :) Check out [Create a Docker group] here https://docs.docker.com/engine/installation/linux/ubuntulinux/ to get rid of the sudo prefix.

Answer 6

I had this problem and did not want to mess things up using sudo. When investigating, I tried to get some info :

docker info

Surprinsingly, I had the following error :

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http:///var/run/docker.sock/v1.38/info: dial unix /var/run/docker.sock: connect: permission denied

For some reason I did not have enough privileges, the following command solved my problem :

sudo chown $USER /var/run/docker.sock

Et voilà !
