Inside actions.py there is the start of the file

Someone have idea in how to install requests in rasa-sdk in the Dockerfile or as a parameter in compose command?

If you need more information, please let me know to share with you.

Answer 1

I have tweaked your Dockerfile:

FROM rasa/rasa-sdk:3.6.2

USER root

RUN apt-get update && \
    pip install --no-cache-dir requests

COPY ./actions /app/actions

USER 1001

Changes:

1. Move COPY to end so that image builds quickly when you make code changes.
2. Change the target for COPY to an absolute path.
3. Consolidate the two RUN commands.

In actions/actions.py:

import requests

print("Hello!")

Build and run.

docker build -t rasa .
docker run -it rasa

Output:

2024-01-23 05:10:29 INFO rasa_sdk.endpoint  - Starting action endpoint server...
Hello!
2024-01-23 05:10:29 INFO rasa_sdk.endpoint  - Starting plugins...
2024-01-23 05:10:29 INFO rasa_sdk.endpoint  - Action endpoint is up and running on http://0.0.0.0:5055

The docker run command in your question appears to run the base image (rasa/rasa-sdk:3.6.2) rather than your derived image.
