THREE FIXES IN ONE SHOT.
1. UPLOAD EACCES (the crashing one)
The /app/public/branding upload was failing with EACCES because the
folder on the host was created by `debian` (uid 1000) but the container
runs as nextjs (uid 1001). Docker bind mounts preserve host ownership,
so the container couldn't write into branding/.
Fix: introduce a docker-entrypoint.sh that runs the container briefly
as root, chowns every public/* mount to uid 1001, runs Prisma migrate
deploy, then drops to nextjs via `su-exec`. From now on every deploy
self-heals permissions across all asset folders (branding, footage,
applications, cases, news, parts, operations-inbox) — even if a future
volume gets added with the wrong owner.
Dockerfile changes:
- Adds `su-exec` package (lightweight gosu equivalent for Alpine)
- Removes the static USER directive (entrypoint manages user transitions)
- Replaces CMD with an ENTRYPOINT pointing at the new script
2. metadataBase WARNING
Server logs were emitting:
⚠ metadataBase property in metadata export is not set ... using "http://localhost:3000"
That's the layout's generateMetadata not declaring metadataBase, so
Next.js couldn't resolve relative OG/Twitter image URLs to absolute
ones. Reading NEXT_PUBLIC_APP_URL (already set in docker-compose env)
and feeding it as `metadataBase: new URL(...)` silences the warning
and produces correct absolute URLs in social previews.
3. PERMISSIONS DOCS
The entrypoint chown is idempotent and silent on non-existent folders,
so future volumes added to docker-compose just work. No more "did you
sudo chown the new folder" gotchas.
DEPLOY (David)
cd /opt/flux-srl
# one-time fix for the existing branding folder so the next deploy
# doesn't have to chown 65MB of data — but the entrypoint now handles
# this automatically anyway:
sudo chown -R 1001:1001 /opt/flux-srl/public/branding
git pull
docker compose up -d --build app
