Docker Daemon Error When Running Docker Compose02 Jan 2018
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.
