Docker run vs Podman run

Question

I have got the following Dockerfile:

FROM node:18.6.0-alpine3.15
RUN apk --no-cache add --virtual .builds-deps build-base python3 python3-dev py3-pip && \
    echo "echo http://dl-cdn.alpinelinux.org/alpine/latest-stable/main" >> /etc/apk/repositories && \
    echo echo "http://dl-cdn.alpinelinux.org/alpine/latest-stable/community" >> /etc/apk/repositories && \
    apk update && apk upgrade && \
    apk add linux-headers && \
    pip3 install --upgrade pip
RUN pip3 install RPi.GPIO rpi_ws281x adafruit-circuitpython-neopixel
WORKDIR /usr/src/app
COPY . .
RUN npm install && mkdir -p backend/images
EXPOSE 3000
CMD [ "node", "server.js" ]

This container image is running on a raspberry pi and I am controlling for example a led stripe.

The weird thing is that everything works with this docker run command:

docker run --rm --name cm_back_test --privileged -e CM_USER=superuser -e CM_PASSWORD=superuser -e CM_CLUSTER=cluster.xxxx.mongodb.net cm-back:1.0.0

I need the privileged flag for the gpio stuff. But for some reasone the exact same command with podman does not work.

Can someone explain me why?
