Start with the docker-compose.yml service definition and reproduce the container with user 1000:1000. Trace the reported failures through /usr/bin/odoo and odoo/cli/server.py, then verify that startup and requests work with the mounted /var/lib/odoo and /mnt/extra-addons paths without permission or UID lookup errors.
