Keep server secrets out of the webapp and admin-dashboard containers #403
Description
Summary
The production compose file gives the webapp and the admin dashboard the whole .env.production through env_file. Neither app uses the server secrets in it. So both containers hold SUPABASE_SERVICE_ROLE_KEY (bypasses all RLS), DATABASE_URL and the storage secret for no reason. Any env leak in a Next app then becomes a full database compromise.
- Severity: Medium
- Area: infra (
docker-compose.prod.yml) - Source: security review of 2026-10-06, finding M5. Confirmed by reading every
process.envuse in both apps.
Where
docker-compose.prod.yml:484(webapp) —env_file: .env.productiondocker-compose.prod.yml:582(admin-dashboard) —env_file: .env.production
What each app really reads at runtime
- webapp:
NEXT_PUBLIC_*,NODE_ENV,NEXT_PHASE,SERVER_RESTAPI_URL,SUPABASE_URL.SENTRY_*is read only at build time inapps/webapp/next.config.js. The only server route isapps/webapp/src/pages/api/health.ts. - admin-dashboard: its
NEXT_PUBLIC_*keys andNODE_ENV.
Re-check with grep -rn "process.env\." apps/webapp/src apps/webapp/next.config.js apps/admin-dashboard/src before you change anything.
Fix plan
- Remove
env_file: .env.productionfrom thewebappandadmin-dashboardservices. - List the needed keys under each service's
environment:block. - Add
SUPABASE_URLto the webapp block. Today it arrives only throughenv_file(apps/webapp/src/utils/supabase/url.ts:3-4). Without it, server-side rendering falls back to the public URL. - Rename
NEXT_PUBLIC_SPACES_SECRET. TheNEXT_PUBLIC_prefix makes Next inline it into the client bundle the day any client code reads it. Update every reader in the same change. - Keep build-time args (
NEXT_PUBLIC_*used at build) as they are in the Dockerfile.
Acceptance criteria
-
docker exec <webapp> envshows noSUPABASE_SERVICE_ROLE_KEY,DATABASE_URLor storage secret. - Same for the admin-dashboard container.
- Webapp SSR, sign-in, documents and chat work in staging.
- Admin dashboard sign-in and pages work in staging.
Note
Deploy to staging first (.github/workflows/stage.docs.plus.yml). A missing key shows only at runtime.

fix(docker): keep server secrets out of the webapp and admin containers

Fixed in
1db1bd3. Both services already listed every runtime key they read, so the change is only: removeenv_file, and addSUPABASE_URLto the webapp.NEXT_PUBLIC_SPACES_SECREThas no reader anywhere, so its line was removed from.env.exampleinstead of being renamed.Before closing: after the staging deploy, check webapp SSR, sign-in, documents and chat, and the admin pages. A missing key shows only at runtime.

Reopened: the board automation closed this issue before the push. The code is on
mainthrough merge083f37d84. It stays open until the staging check in the acceptance criteria passes:docker execenv, SSR, sign-in, documents, chat and the admin pages.HMarzban commentedon Oct 12, 2026
Verified on production, 2026-10-12
The fix (
1db1bd3, merged as083f37d84) has been live since the 2026-10-09 deploy. The latest green deploy is run 38107083947.docker-compose.prod.yml: neitherwebappnoradmin-dashboardhas anenv_file, and neitherenvironment:block names a secret.setorunset, never a value. Indocsplus-webapp-57,docsplus-webapp-58anddocsplus-admin-dashboard-29,SUPABASE_SERVICE_ROLE_KEYandDATABASE_URLare unset. The webapp hasSUPABASE_URL.The staging step was replaced by prod running cleanly for three days. Closing.
