This commit significantly improves the local development experience by enabling hot reloading for the Django application. This is achieved by installing the project as an editable package within the Docker services.
Key changes:
- **Hot Reloading:**
- Modified `docker-compose.yml` for `web` and `celery` services to use `uv pip install --editable . --no-deps`.
- Mounted the project root (`./`) to `/code` in `web` and `celery` services to facilitate the editable install.
- **Docker & Build Enhancements:**
- Added `uv` binary to stage-1 in the `Dockerfile` for faster package operations.
- Adjusted file permissions in `Dockerfile` during the app copy.
- Set `DEBUG=true` for the `web` service in `docker-compose.yml` for easier local debugging.
- Changed `restart` policy to `unless-stopped` for `web` and `celery` dev services.
- Added a healthcheck for the `redis` service in the dev `docker-compose.yml`.
- **Code & Script Cleanup:**
- Removed the custom `HealthCheckView` from the `home` app, as health checks are now handled by django-health-checks.
- Updated paths and commands in `scripts/entrypoint.sh`, `scripts/prebuild.sh`, and `scripts/reset-db_make-migrations_seed-data.sh` to align with the new setup and remove obsolete steps (e.g., db cache table creation; we now use redis).
- **Implemented Dynamic Gatekeeper (Anubis) Proxy:**
- Introduced Anubis as a Gatekeeper proxy layer for services (`web`, `web-staging`, `feedback`, `health`).
- Added `docker-gen` setup (`docker-compose_gatekeeper.template.yml`, `gatekeeper-manager`) to dynamically configure Anubis instances based on container labels (`enable_gatekeeper=true`).
- Updated HAProxy to route traffic through the respective Gatekeeper services.
- **Enhanced Service Health Monitoring & Checks:**
- Integrated `django-health-check` into the Django application, providing detailed health endpoints (e.g., `/health/`).
- Replaced the custom health check view with `django-health-check` URLs.
- Added `psutil` for system metrics in health checks.
- Made Gatus configuration dynamic using `docker-gen` (`config.template.yaml`), allowing automatic discovery and monitoring of service instances (e.g., web workers).
- Externalized Gatus SMTP credentials to environment variables.
- Strengthened `docker-compose_core.yml` with a combined `db-redis-healthcheck` service reporting to Gatus.
- Added explicit health checks for `db` and `redis` services in `docker-compose.yml`.
- **Improved Docker & Compose Configuration:**
- Added `depends_on` conditions in `docker-compose.yml` for `web` and `celery` services to wait for the database.
- Updated `ALLOWED_HOSTS` in `docker-compose_staging.yml` and `docker-compose_web.yml` to include internal container names for Gatekeeper communication.
- Set `DEBUG=False` for staging services.
- Removed `.env.production` from `.gitignore` (standardized to `.env`).
- Streamlined `scripts/entrypoint.sh` by removing the call to the no-longer-present `/deploy.sh`.
- **Dependency Updates:**
- Added `django-health-check>=3.18.3` and `psutil>=7.0.0` to `pyproject.toml` and `uv.lock`.
- Updated `settings.py` to include `health_check` apps, configuration, and use `REDIS_URL` consistently.
- **Streamlined deployment script used in GHA:**
- Updated the workflow to copy new server files and create a new `.env` file in the temporary directory before moving them into place.
- Consolidated the stopping and removal of old containers into a single step for better clarity and efficiency.
- Reduce container downtime by rearranging stop/start steps.
