docker-compose fails at PyYAML==6.0

[aebgit]

When installing i noticed two issues:

1. docker compose build throws docker: 'compose' is not a docker command., so I assume you meant docker-compose build instead
2. when running docker-compose build from inside ~/homeassistant-bluetooth-mesh/docker, this fails with the error below:

Collecting PyYAML==6.0

I googled around and this seems to be a known problem with PyYAML==6.0. However I couldn't solve it by redirecting to another version, because it seems docker-compose uses the requirements.txt from your Github-repo and not my local file.

Looking forward for any advice!

Hello Andreas,

thanks for the feedback. Regarding your first point, compose is being integrated into docker as a CLI plugin and therefore the command changed from docker-compose to docker compose (see for example https://stackoverflow.com/a/66516826/12661819).

I am not sure about the problem with PyYaML. I currently do not have the time to look into it, but I guess you can change the Dockerfile to copy the local files instead of cloning the repo (now that I see that, its weird that I did that in the first place).

Due to the current directory structure, I guess you have to add the context: prop under build: in docker-compose.yaml, so it would look something like this

   ...
    build:
      context: ../
      dockerfile: ./docker/Dockerfile
   ...

and then change all local paths in the Dockerfile accordingly. Then you should be able to change

RUN git clone https://github.com/dominikberse/homeassistant-bluetooth-mesh.git .
RUN git checkout master

to

COPY . .

which will copy your local files instead of cloning the repo.

You will probably have to adjust some of this, I just wrote it down here without further tests. But it's a good starting point hopefully.

Good luck,
Dominik

Hi there, I fixed this by changing the pip install line in the Dockerfile:

RUN pip3 install --upgrade pip && pip3 install "cython<3.0.0" wheel && pip install "pyyaml==6.0" --no-build-isolation && pip3 install -r requirements.txt

Then remove cython from the requirements.txt.
