Edge Functions and Environment vars in Docker

[Antiokh]

Hi! I'm trying to host the Supabase in Docker.

I've found that I can set additional variables in a docker-compose.yml like

  functions:
    container_name: supabase-edge-functions
    image: supabase/edge-runtime:v1.67.4
    restart: unless-stopped
    volumes:
      - ./volumes/functions:/home/deno/functions:Z
    depends_on:
      analytics:
        condition: service_healthy
    environment:
      *Deno.env.get("MY_API_KEY"): ITS_VALUE*
      JWT_SECRET: ${JWT_SECRET}
      SUPABASE_URL: http://kong:8000
      SUPABASE_ANON_KEY: ${ANON_KEY}
      SUPABASE_SERVICE_ROLE_KEY: ${SERVICE_ROLE_KEY}
      SUPABASE_DB_URL: postgresql://postgres:${POSTGRES_PASSWORD}@${POSTGRES_HOST}:${POSTGRES_PORT}/${POSTGRES_DB}
      # TODO: Allow configuring VERIFY_JWT per function. This PR might help: https://github.com/supabase/cli/pull/786
      VERIFY_JWT: "${FUNCTIONS_VERIFY_JWT}"
    command:
      [
        "start",
        "--main-service",
        "/home/deno/functions/main"
      ]

How can I setup a dedicated file to have any secrets and keys used in many edge functions via Deno.env.get("Deno.env.get("MY_API_KEY")") or something similar?

Is there any detailed self-host guide on how to setup edge-functions in Docker correctly?

This has been long overdue - for which accept my apologies. Added here - https://supabase.com/docs/guides/self-hosting/self-hosted-functions :)

Hope this helps
