Error at build docker image in Raspberry pi

Question

I am trying to build a image in my RaspBerryPi 4 with raspbian. I want to make a docker image that run a python Image: my directory is:

analizador_doff
  | tarea_periodica.py
  | Dockerfile
  | requirements.txt

my dockerfile is:


# syntax=docker/dockerfile:1

FROM python:3.9

WORKDIR /analizador_dof

ENV PYTHONUNBUFFERED=1

COPY requirements.txt requirements.txt
USER root
RUN pip3 install --user -r requirements.txt

COPY . .
CMD [ "python3", "-m" , "tarea_periodica", "run", "--host=0.0.0.0"

I use this build comand: sudo docker build /media/pi/NAS/analizador_dof -t analizador_dof

I get an error in the pip3 instalation:

Sending build context to Docker daemon   42.5kB

You need to specify the docker image tag approriate for the Rasp pi OS. I received this error and changed

FROM arm32v7/python:3.6-buster

to resove the error. You can find the best tag based on the OS version you are running. Find this out with

cat /etc/os-release

As the error states you should propably add a link to your local timezone like this

RUN ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime

it helped me with my settup a few weeks ago In my case Europe/Berlin is correct. But you can use yours or the UTC +0 as you whish.
