Previously re-running the installer always overwrote config.yml and .env
from scratch, silently discarding any real camera credentials already on
disk. Now install_frigate parses an existing config.yml + .env (best-effort,
matching this installer's own output shape) and presents a numbered list
of detected cameras with a menu:
[1] Keep everything as-is (no changes at all)
[2] Backup existing config and start fresh
[3] Add more cameras (keep these)
[4] Remove cameras (choose numbers, or 'all'), then optionally add more
Implementation switches from building config.yml/.env as concatenated text
blocks inline in the collection loop to parallel CAM_* bash arrays
(name/ip/port/var-names/enabled/notify/substream-suffixes), so cameras can
be parsed, listed, removed, and re-rendered independently:
- _frigate_parse_existing: reads go2rtc streams + cameras: enabled/notifications
from config.yml, and credential values from .env, into the CAM_* arrays
- _frigate_review_existing: numbered menu, mutates arrays per choice
- _frigate_next_suffix_int: kept cameras retain their existing FRIGATE_RTSP_USER[N]
var names unchanged; new cameras get the next unused numeric suffix so
credentials never collide after removals
- _frigate_camera_wizard / _frigate_render_config: same prompts and output
shape as before, now array-driven so kept + new cameras render uniformly
- _frigate_backup_existing: copies config.yml/.env/docker-compose.yml to a
timestamped backup-YYYYMMDD-HHMMSS/ dir before any destructive rewrite
Verified with a 5-scenario test harness (fresh install, keep-as-is producing
byte-identical output, add-camera preserving existing credentials, remove-
by-number without var collisions, backup-and-fresh) before committing.
