My Raspberry Pi camera is running on my RP3 and works fine. I am trying to run it inside a docker container, but I keep running into the
* failed to open vchiq instance error.
This is my Dockerfile
FROM resin/rpi-raspbian:latest RUN apt-get update -y RUN apt-get upgrade -y RUN apt-get install -y wget RUN apt-get install libraspberrypi-bin -y RUN usermod -a -G video root RUN apt-get -q update \ && apt-get -qy install \ curl \ debootstrap \ python3 \ python3-pip \ ca-certificates \ && rm -rf /var/lib/apt/lists/* COPY ./requirements.txt /requirements.txt RUN pip3 install -r requirements.txt COPY ./src /src ENTRYPOINT ["/bin/bash"]
and this is the simple Python script I am trying to run (right now, without a volume):
import datetime from picamera import PiCamera from time import sleep camera = PiCamera() while True: now = str(datetime.datetime.now()) camera.start_preview() sleep(3600) print("Capturing at:", now) camera.capture('~/data/images/' + now + '.jpg') camera.stop_preview()
My problem is identical if I try to run other Docker images based off other builds, e.g. this repo.
I have tried to add root to the video group
RUN usermod -a -G video root both under build and when running the container. I have tried to run the container with
--device /dev/vchiq added to
docker run, but I simply get
Command not found: --device when doing so.
