Docker

Usage

In order to start an action server using implemented custom actions, you can use the available Docker image rasa/rasa-sdk:latest.

Before starting the action server ensure that the folder containing your actions is handled as Python module and therefore has to contain a file called __init__.py

Then start the action server using:

docker run -p 5055:5055 --mount type=bind,source=<ABSOLUTE_PATH_TO_YOUR_ACTIONS>,target=/app/actions \
	rasa/rasa-sdk:latest

The action server is then available at http://localhost:5055/webhook.

Custom Dependencies

To add custom dependencies you enhance the given Docker image, e.g.:

FROM rasa/rasa-sdk:latest

# To install system dependencies
RUN apt-get update -qq && \
    apt-get install -y <NAME_OF_REQUIRED_PACKAGE> && \
    apt-get clean && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

# To install packages from PyPI
RUN pip install --no-cache-dir <A_REQUIRED_PACKAGE_ON_PYPI>

Code Style

To ensure a standardized code style we use the formatter black. If your code is not formatted properly, travis will fail to build.

If you want to automatically format your code on every commit, you can use pre-commit. Just install it via pip install pre-commit and execute pre-commit install.

If you want to set it up manually, install black via pip install black. To reformat files execute

black .
