Need help with a new addon Dockerfile and .yaml

Hi,
I need a little help with configuring my python skrip to a homeassistant addon.
Here are my Addon files.
For testing i copy this files to addons directory via smb.

My problems are:

  • I cannot find addons dir path in docker Contailner, mapped in config.yaml
  • the cache of docker is a big problem, so i decided to add build args in build.yaml → does not work

The baseControl skrip needs to be configured with a file called project.json and secure.json. My plan is to copy these files to the addons dir via smb and can read it in my Container. Is that the/a right way to do this?

Any ideas?
I cannot find these information in doku.
