I am trying to install lemmy via Docker on Debian. I've configured Postgres and my config files but I'm getting an error when I try to docker compose up -d.

$ docker compose up -d

Googling this error leads me to believe its a docker issue, but I'm not quite sure how to go about fixing it. Thanks!
