# roms stack — RomM ROM library manager + its dedicated MariaDB.
#
# RomM bundles its own Redis (persisted via /redis-data), so there is no cache
# container here. The library is the existing EmuDeck tree at /storage1/Emulation,
# which is already RomM "Structure A" (a roms/ parent with per-platform subfolders).
# It is mounted READ-WRITE per request, so RomM file operations (rename/move/
# delete, manual matches) can mutate the tree — default scanning stays read-only.
#
# All secrets/config come from env_file (stack.env) using container-exact var
# names (DB_PASSWD, MARIADB_PASSWORD, ...), so this git stack needs NO Portainer
# UI env vars for ${VAR} substitution. See memory portainer-env-interpolation.
#
# Tiered binds: DB + RomM config + bundled-redis -> /config/romm (SSD);
# RomM blobs (downloaded art + user saves/states) -> /storage1/labdata/romm (ZFS).
# The labdata/romm/* targets are auto-created by Docker as root on first start.
#
# Only romm joins `edge` (Caddy proxies romm:8080); romm-db stays on `roms` only.
#
# To share RomM with an EXTERNAL tailnet user (a friend on his own tailnet), see
# the dedicated `share` stack (stacks/share/), which runs a Tailscale `serve`
# node joined to this `roms` network.
