Extending rasa docker for a new spacy language model

Rasa Open Source
1

Hi,

I’m using the docker guide at https://rasa.com/docs/rasa/docker/building-in-docker which mentions “If your model has a dependency that is not included in any of the tags (for example, a different spaCy language model), you can build a docker image that extends the rasa/rasa image.”

I would like to add the Dutch language, so I’ve made a custom Dockerfile containing these lines:

FROM rasa/rasa:1.10.14-full

RUN python -m spacy download nl_core_news_sm
RUN python -m spacy link nl_core_news_sm nl

(The commands come from https://legacy-docs-v1.rasa.com/user-guide/installation/#dependencies-for-spacy)

However, upon building my image I get an error:

docker build -t rasatest .

What am I supposed to do to fix this? Seems to be an issue with the original rasa image?

Best regards!

Found it, on one of the other rasa pages… so too well hidden.

I have to change from user 1001 to root first, and then go back. The final Dockerfile is:

FROM rasa/rasa:1.10.14-full

# Change back to root user to install dependencies
USER root

RUN python -m spacy download nl_core_news_sm
RUN python -m spacy link nl_core_news_sm nl

# Switch back to non-root to run code
USER 1001
