# LibNovel homelab runner
#
# Connects to production PocketBase and MinIO via public subdomains.
# All secrets come from Doppler (project=libnovel, config=prd_homelab).
# Run with: doppler run -- docker compose up -d
#
# Differs from prod runner:
#   - RUNNER_WORKER_ID=homelab-runner-1  (unique, avoids task claiming conflicts)
#   - MINIO_ENDPOINT/USE_SSL → storage.libnovel.cc over HTTPS
#   - POCKETBASE_URL          → https://pb.libnovel.cc
#   - MEILI_URL               → https://search.libnovel.cc (Caddy-proxied)
#   - VALKEY_ADDR             → unset (not exposed publicly)
#   - RUNNER_SKIP_INITIAL_CATALOGUE_REFRESH=true
#   - Redis service for Asynq task queue (local to homelab, exposed to prod via Caddy TCP proxy)
#   - LibreTranslate service for machine translation (internal network only)
