Docker Daemon Error When Running Docker Compose

docker why

TL;DR Make sure you don’t have any old mounted volumes around if you see the error below.

I just got the following error when trying to run docker-compose up -d

ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?

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

Please note I have a database using a mounted volume. The issue was that the previous mount was still present. Once I deleted that, docker-compose up -d would work jut fine.

If anyone knows a more elegant way to handle this, I’m open to it.
