From a5048634b8df85276fcabc0defef01fcf06d446c Mon Sep 17 00:00:00 2001 From: denshooter Date: Tue, 17 Feb 2026 15:33:27 +0100 Subject: [PATCH] fix: add DB wait-for-ready logic and explicit network names - start-with-migrate.js now waits for the database TCP port to be reachable before running Prisma migrations (15 retries, 2s interval). Prevents the container from crashing and restarting in a loop when postgres is still starting up. - Add explicit 'name:' to both production and dev compose networks to prevent docker-compose project prefix mismatch.
