Environment variables
  • ENGRAPHY_DATABASE_URLrequiredsecretlibpq connection string for a Postgres 16 database with the pgvector extension, reached as the non-superuser `engraphy_app` role. Required: the server refuses to start without it, and refuses to start if the schema is behind (run `engraphy-admin migrate` first).
  • ENGRAPHY_BIND_HOSTInterface the server binds. Containers reach their own loopback only, so a published container sets 0.0.0.0 and puts the boundary at the port publication and the reverse proxy.
  • ENGRAPHY_BIND_PORTPort the server binds inside the container, matching the port in the transport URL.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
