Next.js bakes NEXT_PUBLIC_* vars into the client JS bundle at build time, not runtime. The admin image was being built with admin/.env.local containing NEXT_PUBLIC_API_URL=http://localhost:8000, hardcoding localhost into the browser bundle. The runtime configMap value had no effect on the already-compiled JS, causing prod admin login to throw CORS errors hitting localhost. Fix: - Dockerfile: admin-builder stage accepts ARG NEXT_PUBLIC_API_URL and strips any committed .env.local/.env.development.local before npm run build. - .dockerignore: explicitly exclude admin/.env.* (root-level .env.* pattern doesn't match nested paths), so a local dev .env.local can never sneak into the build context again.
