- Around line 29-34: The deriver service starts src.deriver directly and
bypasses docker/entrypoint.sh (which runs scripts/provision_db.py to apply
migrations), so change the deriver service's depends_on to also wait for the API
to start: add the api service under depends_on for the deriver service and use
condition: service_started (since api has no healthcheck) so the API’s
entrypoint can run migrations before src.deriver launches; reference the deriver
service, entrypoint, src.deriver, docker/entrypoint.sh, and
scripts/provision_db.py when making the change.
- Around line 18-23: The docker-compose currently hardcodes DB_CONNECTION_URI in
the api and deriver services and sets the database to use trust auth and
publishes 5432; remove the hardcoded connection string from the api and deriver
service environment blocks so they do not override .env (use env_file or
variable interpolation like DB_CONNECTION_URI=${DB_CONNECTION_URI}), remove
POSTGRES_HOST_AUTH_METHOD=trust from the database service, stop publishing port
5432 publicly (either remove ports or bind to 127.0.0.1:5432), and set explicit
secure vars for the DB in env_file (e.g., POSTGRES_USER, POSTGRES_PASSWORD,
POSTGRES_DB) so credentials come from .env and not from the compose file. Ensure
references: DB_CONNECTION_URI, env_file, database service, api service, deriver
service, and POSTGRES_HOST_AUTH_METHOD are updated accordingly.
- Around line 99-105: Replace the hardcoded Grafana environment variables
(GF_SECURITY_ADMIN_USER, GF_SECURITY_ADMIN_PASSWORD, GF_AUTH_ANONYMOUS_ENABLED,
GF_AUTH_ANONYMOUS_ORG_ROLE) with an env_file reference so secrets/config are
loaded from a separate .env or secrets file; update the docker-compose service
block that exposes port 3000 to include an env_file: entry and remove the inline
GF_SECURITY_ADMIN_USER and GF_SECURITY_ADMIN_PASSWORD lines (also consider
removing or setting GF_AUTH_ANONYMOUS_ENABLED to false in the env file) so
credentials are not committed in the compose file.

Docker Compose environment variable precedence env_file vs environment
💡 Result:
In Docker Compose, when the same environment variable is defined in both the environment attribute and env_file attribute in the compose file, the environment attribute takes precedence over env_file. The full order of precedence (highest to lowest) for environment variables in the container is: 1. Set using docker compose run --env (CLI). 2. Set with environment or env_file but with value interpolated from shell or .env file (via ${VAR}). 3. Set using just the environment attribute (plain values) in the Compose file. 4. Set using the env_file attribute in the Compose file. 5. Set in the container image via ENV in Dockerfile. Example from official docs: services: webapp: image: 'webapp' env_file: - ./webapp.env # VALUE=1.6 environment: - VALUE=1.7 Result: Container gets VALUE=1.7 from environment, overriding env_file. Note: The project-level .env file (auto-loaded) is for interpolation in the compose file, not directly for container env (unless referenced via env_file or interpolated). Multiple env_files are merged with later files overriding earlier ones.

Postgres POSTGRES_HOST_AUTH_METHOD=trust security implications docker official image
💡 Result:
In the official postgres Docker image, setting POSTGRES_HOST_AUTH_METHOD=trust tells the entrypoint (at initial database creation) to configure host (TCP/IP) connections to use the trust auth method—so POSTGRES_PASSWORD is not required. The image already enables trust for some local access inside the container, but this variable extends the idea to host connections. [1]
Security implications
- No authentication for TCP clients: PostgreSQL’s
trustmethod means anyone who can connect to the server can log in as any PostgreSQL user without a password (including potentiallypostgres). [2] - Risk becomes “network = security boundary”: If you publish Postgres to the host (
-p 5432:5432), run on a shared network, misconfigure Kubernetes/Cloud networking, or otherwise make the port reachable, an attacker who can reach the port can likely get in immediately. (This is why “trust” is widely warned against outside isolated dev/test.) [2][3] - Hardening tools may block it: Docker’s “Hardened Images” guidance for Postgres explicitly disallows
trust/passwordforPOSTGRES_HOST_AUTH_METHOD“for security reasons” (showing how unsafetrustis considered for production-like usage). [4]
Practical guidance
- Use
POSTGRES_PASSWORD(or secrets) and a password-based method (preferably SCRAM) instead oftrust, and don’t expose 5432 publicly—keep Postgres on a private Docker network or behind strict firewalling / tunneling. [1][2]
Sources: Docker Official Image docs for postgres [1], PostgreSQL docs on trust meaning “login as any user without a password” [2], Cloud Security Alliance note on enabling trust via POSTGRES_HOST_AUTH_METHOD [3], Docker Hardened Images guide noting restrictions for security [4].
Remove hardcoded database credentials and don't expose Postgres with trust authentication.
The api and deriver services hard-code DB_CONNECTION_URI=postgresql+psycopg://postgres:postgres@database:5432/postgres, and Docker Compose gives environment precedence over env_file, so any safer values in .env are ignored. The database service publishes port 5432 to all host interfaces with POSTGRES_HOST_AUTH_METHOD=trust, which allows anyone with network access to connect without a password—no credentials required. On a VPS or shared network, this is an exposed superuser database.

Wait for API startup before starting the worker.
docker/entrypoint.sh runs scripts/provision_db.py, which executes Alembic migrations and schema setup (create schema, install pgvector, run migrations). The deriver service bypasses this entirely and starts src.deriver directly. Since docker-compose only waits for services listed under depends_on, the worker can start as soon as Postgres and Redis are healthy, even before the API finishes schema initialization.
The suggested fix references api: condition: service_healthy, but the api service has no healthcheck defined, making that impossible to implement. Use condition: service_started instead to wait for the API to start, which triggers the migration sequence:
deriver:
depends_on:
+ api:
+ condition: service_started
database:
condition: service_healthy
redis:
condition: service_healthy📝 Committable suggestion

Add env_file entry and remove hardcoded Grafana admin credentials.
Grafana is configured with default credentials (admin/admin) and anonymous access enabled on port 3000. While this is an example template, it sets a poor security baseline that users may not customize. Other services in the compose file use env_file to manage secrets—Grafana should follow the same pattern:

Problem
The deriver container becomes unhealthy because it tries to bind port 9090 for its Prometheus metrics server (METRICS_ENABLED=true), but port 9090 is already used by the Prometheus sidecar container defined in the same docker-compose file.
Solution
Files changed
Testing
Verified on VPS: deriver container stays healthy after restart with no port conflicts.
