Local docker works ok:

Odoo 13 Community

volume: /mnt/extra-addons

Docker build from: https://github.com/odoo/docker/blob/f116a674ca62595d0fbf1ded206ec2e4d962ebf0/13.0/Dockerfile

Run through docker compose with separeted postgres.

When I add new app to /mnt/extra-addons it works, all static content 200

When I deploy it to kube, I received 404. All configuration and resources are the same. I even enter into container, and checked permission correct, paths correct.

I don't have idea how to debug it further.
