When using Docker and Traefik, I was unable to connect ("Bad Gateway") and getting the error:
nc: getaddrinfo: Name does not resolve
This may be obvious to most, but I wanted to post my solution in case it is helpful to someone else.
If you are bind mounting a Docker volume to /config on the containers, it is necessary to chown the volume before running docker-compose up:
docker create volume bookstack
chown -R 1000:1000 /var/lib/docker/volumes/bookstack
docker-compose up -d
Thank you, Linuxserver.io, for the awesome service you have provided.
