Implements automatic version validation for external databases in modular mode to ensure compatibility.
Changes:
- Added check_external_postgres_version() in 02-postgres.sh
- Integrated version check in entrypoint.sh after database connection
- Enforces minimum PostgreSQL version matching DispatcharrBase
- Allows newer versions with forward compatibility notice
- Rejects older versions with clear upgrade instructions
The version requirement automatically scales when DispatcharrBase is updated, requiring no manual maintenance. Only applies to modular deployments using external databases; AIO deployments are unaffected.
Tested and verified correct behavior with PostgreSQL v17, v18, and v16
Make database ports configurable for users with external PostgreSQL/Redis.
- Add POSTGRES_PORT and REDIS_PORT to docker-compose.yml (web and celery)
- Remove hardcoded CELERY_BROKER_URL (Django builds it from components)
- Add REDIS_PORT export to entrypoint.sh and profile variables
- Add Redis connection check for modular mode (matches PostgreSQL pattern)
Users can now specify custom ports for external databases:
[defaults]
POSTGRES_PORT=5432
REDIS_PORT=6379
Extend ensure_utf8_encoding() to support both internal and external PostgreSQL.
- Modular mode: Uses TCP connection with PGPASSWORD authentication
- AIO mode: Uses Unix socket as postgres user
- Explicitly set database owner during recreation (fixes missing --owner flag)
- Conversion logic (dump/drop/recreate/restore) works for both AIO and modular modes
- Skip internal PostgreSQL setup entirely when DISPATCHARR_ENV=modular
- docker-compose: added service health checks
- dockerfile: added if logic for sed command so missing files do not cause build fail
- entrypoint.celery: change migration detection to not continue until ALL migrations are applied
- entrypoint: trim django key and change external postgres check to python in case postgres binaries are missing
- docker/entrypoint.sh: Conditional PostgreSQL init/startup for modular mode
- docker/entrypoint.celery.sh: New dedicated entrypoint for celery container - prevents race condition in modular deployment
- docker/uwsgi.modular.ini: New uWSGI config without Redis/Celery daemons
- docker/Dockerfile: Add line ending fixes and chmod for entrypoints - adds cross-platform support for image builds
- docker/docker-compose.yml: Configure modular mode with DISPATCHARR_ENV - uses new celery entrypoint and adds depends_on to prevent race condition
