Action server not working with docker-compose and custom credential file

My project structure looks like this

.
└── rasa2/
    ├── actions/
    │   ├── __init__.py
    │   ├── action1.py
    │   ├── action2.py
    │   └── action3.py
    ├── data
    ├── models
    ├── __init__.py
    ├── actions.py
    ├── config.yml
    ├── domain.yml
    ├── endpoints.yml
    ├── intern_cred.yml
    └── load_credentials.py

Because I connect to several databases I have created a intern_cred.yml file where the credentials for the databases are stored. I have a helper script load_credentials.py to load the yml file. I can start both rasa-server and rasa action server on the terminal but if I want to use docker-compose it fails.

Here are my files:

actions.py

from actions import action1
from actions import action2
from actions import action3
import load_credentials

action1 
action2
action3
load_credentials

load_credentials.py

import yaml
try:
    with open('./intern_cred.yml') as creds:
        credentials = yaml.load(creds)
except:
    print("some error occured")

action1.py

from __future__ import absolute_import
from __future__ import division
from __future__ import unicode_literals

    def run(self, dispatcher, tracker, domain):
       dispatcher.utter_message("Example")

docker-compose

version: '3'
services:
  rasa:
    container_name: rasa-server
    image: rasa/rasa:2.0.0-full
    ports:
      - 5005:5005
    volumes:
      - ./:/app
    command:
      - run

  app:
    container_name: rasa-action-server
    image: rasa-action-server:rasa-action-server-1
    ports:
      - 5055:5055

I followed the instructions in the docs and build my action server image. If i try to run the image i get following error:

2021-02-01 14:17:04 INFO rasa_sdk.endpoint - Starting action endpoint server...
2021-02-01 14:17:04 ERROR rasa_sdk.executor - Failed to register package 'actions'.

from load_credentials import credentials
ModuleNotFoundError: No module named 'load_credentials' 

As I said, if i start the action server from the terminal everything is ok, but not if i start the action-server image. So I asume I messed something up with the helper script where I load the credentials from the yml file.

Can somebody help me to get this working?

PS: intern_cred.yml and load_credentials.py should stay in the project root folder.

I found the solution a few minutes I wrote this post. I copied both load_credentials.py and intern_cred.yml in my dockerfile.

So here is the updated file.

# Extend the official RASA SDK image

# Use subdirectory as working directory
WORKDIR /app

# Copy any additional custom requirements, if necessary (uncomment next line)
COPY actions/requirements-actions.txt ./

# Change back to root user to install dependencies

# Install extra requirements for actions code, if necessary (uncomment next line)
RUN pip install -r requirements-actions.txt

# Copy actions folder to working directory
COPY ./actions /app/actions
COPY ./load_credentials.py /app/load_credentials.py
COPY ./intern_cred.yml /app/intern_cred.yml
