Error when building with pip requirements.txt

I am tring to control LED connected to RPi by using python image.
In the folder I have Dockerfile:

FROM balenalib/raspberrypi3-fedora-python:latest
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD [ "python", "./" ]

in the requirements.txt file i have one line:


When i push i get this error:

Is pip already installed in the image?
Please suggest.

between: during build sometime i get:

An error occured: read ECONNRESET

Is there any interruption on build server?

Hi, sorry, we had an unexpected incident with our builders, that is being fixed up at the moment, you can see the status here:

The builder issues are now resolved, could you retry the push again? Sorry for the inconvenience.

thanks it works. by the way I have changed the base image to:

 FROM balenalib/raspberrypi3-python:3.6-jessie-build


Yeah, the base image change is not related to this issue today. Glad to hear that things work for you now, cheers!
