Setting up our Rasa/NLU container, error? - docker

Question

I have this file Dockerfile.nlu
FROM chatbot/spacy:latest
WORKDIR /app
COPY nlu ./agent_nlu
RUN python –m rasa_nlu.train --config agent_nlu/config.yml --data agent_nlu/data/ --path agent_nlu/agent --fixed_model_name default
and I get the error below:
]$ sudo docker build -t nlu:latest -f docker/Dockerfile.nlu .
Sending build context to Docker daemon 9.216kB

Answer 1

It doesn't look like Docker can find the nlu directory. Are you sure it exists? Are you sure that you are executing the command from the correct directory?
But you also aren't installing Rasa at all or any of it's requirements. Is there a reason you aren't using the pre-built Rasa images? available here with docs here.
Here is a fully functional Docker file pulled from their repo.
