The upstream entrypoint serialises its first-run init with flock on friendica-init-sync.lock inside the shared /var/www/html, which sits on NFSv4 on this branch; local_lock=flock is silently ignored on vers=4 mounts, the lock contends across replicas over server-side locking and the set -eu entrypoint dies with exit 65 on every worker, pushing all replicas onto the manager. Build a custom image whose entrypoint gate lets only task slot 1 run the init while other slots wait until the volume VERSION matches the image VERSION - the same pattern nextcloud already uses.
