Unable to run docker-compose

Following this article on Jhipster, I build the project. I, however, can't run docker-compose. So, I try to figure out the problem. I walk step by step with this Docker-Compose article without luck. 

$ sudo service docker status

$ sudo usermod -aG docker ${USER}

$ docker-compose -f docker-compose.yml build --build-arg UID=$(id -u)
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

The result of the last step is the same as "docker-compose up -d". According to the article, it would be a permission problem if the problem still exists at this point. How can I find what permission issue?

There are multiple ways you can solve this problem. Firstly try to export environment variable of docker host with command:

export DOCKER_HOST=/var/run/docker.sock

If it works you can add the same line to your bashrc config to save this export permanently.

If it doesn't work you can try to modify docker daemon config. It located in

/etc/docker/daemon.json

You'll need to append the localhost to your hosts like that:

"hosts": ["old_hosts_not_modified_only_append_new_one", "tcp://localhost:2376"],

and restart docker daemon using command:

service docker restart

Hope it gonna help ya
