First-time setup
Create the shared Docker network before starting any service:
docker network create app-shared-net
Create .env from .env.example and fill production values. Do not commit .env.
Deployment order
The GitHub deploy workflow combines the active compose files automatically. For manual deployment, use this order:
# 1. Shared services
docker compose -f infra/compose/shared.yml up -d
# 2. Message bus + Dapr placement
docker compose -f infra/compose/nats.yml up -d
docker compose -f infra/compose/dapr.yml up -d
# 3. Reverse proxy
docker compose -f infra/compose/traefik.yml up -d
# 4. Application services (with Dapr sidecars)
docker compose -f infra/compose/scraper.yml up -d
Environment variables
Common variables used by infra compose files:
DATABASE_URL=
GITHUB_TOKEN=
SHARED_REDIS_EXPOSE=127.0.0.1:6379:6379
Traefik certificate path variables are optional because infra/compose/traefik.yml provides production-compatible defaults. See infra/traefik/TRAEFIK_ENV_CONFIG.md for the full list.
Traefik
Traefik reads dynamic config from infra/traefik/dynamic/:
apps.yaml— routers and upstream servicesmiddlewares.yaml— shared middleware chainsssl.yaml— TLS certificates forasepharyana.my.idandasepharyana.web.id
Validation
Run syntax checks after editing infra YAML:
python - <<'PY'
import pathlib, yaml
for path in pathlib.Path('infra').rglob('*.yml'):
with path.open() as fh:
yaml.safe_load(fh)
print(f'OK {path}')
for path in pathlib.Path('infra').rglob('*.yaml'):
with path.open() as fh:
yaml.safe_load(fh)
print(f'OK {path}')
PY
Check compose rendering when Docker is available:
for f in infra/compose/*.yml; do
docker compose -f "$f" config >/dev/null && echo "OK $f"
done
