How to update Optional Requirements from local_requirements.txt file in netbox-docker

[spot62]

netbox-community/netbox#20816 says, to update Optional Requirements dependencies need use local_requirements.txt file
How me do this in netbox-docker?

What I do:

Create local_requirements.txt

icmplib==2.1.1

Create Dockerfile.ext:

FROM netboxcommunity/netbox:latest

# Copy your plugin requirements file into the container
COPY ./local_requirements.txt /opt/netbox/

# Install the Python libraries within NetBox's virtual environment
RUN /usr/local/bin/uv pip install -r /opt/netbox/local_requirements.txt

Create custom container
sudo docker build -f Dockerfile.ext -t netbox-dev .

Create docker-compose.override.yml

services:
  netbox:
    # build:
    #  context: .
    #  dockerfile: Dockerfile.ext
    image: netbox-dev:latest
    ports:

Run
docker compose up -d

Try:

$ docker compose exec netbox bash

Ok.

When run it in NetBox WebUI:

ERROR   ModuleNotFoundError: No module named 'icmplib'
DEBUG   ['/opt/netbox/netbox', '/usr/lib/python312.zip', '/usr/lib/python3.12', '/usr/lib/python3.12/lib-dynload', '/opt/netbox/venv/lib/python3.12/site-packages']

Why? How me fix it?

Thank you.
