docker-compose up failing in Ubuntu 18.04

Question

docker-compose up is failing with the following error.

```sh
$ docker-compose up
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.
```

Check the `docker ps` command once, hope that will also fail. 
This looks like a permission issue for your current user. Try running the following command and try again

```sh
sudo chmod 666 /var/run/docker.sock
```
