Retrofits the standard multi-instance pattern (documented in CLAUDE.md) onto actualbudget, filebrowser, fmd, homebox, immich, jellyfin, joplin, lyrion, meshcentral, ntfy, rustdesk, unifi, and vaultwarden. First instance of each keeps its original name/paths/ports unchanged; adding a second instance prompts for a short name and auto-scans for free ports. Service-specific handling beyond the base pattern: - joplin, immich, unifi: dedicated Postgres/Mongo container per instance (not shared), matching the backup-isolation reasoning in CLAUDE.md. - meshcentral, unifi: multiple fixed ports scanned/shifted together so they stay paired per instance. - rustdesk: 6-port block shifted by a fixed offset per instance, since the image hardcodes its internal ports with no per-port env override. - jellyfin: DLNA/discovery UDP ports only published for the first instance to avoid a host-wide fixed-port conflict. - lyrion: first instance keeps network_mode: host (required for Chromecast/Squeezebox broadcast discovery); additional instances fall back to bridge networking with auto-scanned ports, trading away zero-config discovery since a second container can't also bind host networking's fixed ports. - magicmirror.sh already had its own working multi-instance pattern (upfront instance count, numbered subdirs) and was left as-is. Verified via bash -n on every changed file, plus scripted functional runs (fake docker/ss) exercising first + second instance installs for every port-scanning shape used here (single, dual-paired, quad-paired, block-offset) and confirming dedicated per-instance DB naming and the lyrion host->bridge compose output.
