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?

I have been using same image on save ubuntu version, since past 4 months. But now when I run docker-compose up --build I always get this error:

What could be the issue? Thanks

Here I'm trying to build a terraform image using Alpine with the following Dockerfile, but success. However same used to work until a few months ago, not sure went changed

When I run the command docker image build -t terraform:0.15.5 . I get below-shown error
there is a problem in your Dockerfile that you copied here I think jenkins should not be there. Anyway, I tried with the Dockerfile below and build was success, I couldn't reproduce the problem, Are there any other lines in your Dockerfile ?

Once I've done with Django application I created pull request and merged 2 branches, pushed and released the container to Heroku but for no reason an error occured:

I tried to rename file, copy it to another folder, but nothing worked. The only way I found was to roll back but that makes no sense. How to fix it?
I'm moving my Django application (same as described here) from local machine to Docker container.
I'm redirecting users that come to port 80 from Nginx to Gunicorn via unix:run/gunicorn.sock It works on my local machine, but I7m not sure how to describe this action in Dockerfile.
Right now I'm doing it this way, but it won't works...

EXPOSE 80
CMD ["gunicorn", "--bind", "unix:run/gunicorn.sock", "--workers", "3", "mediadbin.wsgi:application", "--name", "mediadbin"]
Also it won't throw an Error or somthing like that, so I'm not sure what is wrong...
I'm able to run Gunicorn without Nginx via port 8000 in my container when I edit a little bit the script above
I have a Docker container that has two conda environments in it. One is used the vast majority of the time so I would like to automatically start in that environment (currently in starts in the base environment). Based on this website I tried by adding this to the end of my Dockerfile:
# Activate env
SHELL ["conda", "run", "-n", "py3", "/bin/bash", "-c"]
ENTRYPOINT ["conda", "run", "-n", "py3", "python", "pass.py"]
where run.py just contains print("hello world").
This caused the script to run but the docker container does not remain open after I run the docker container, although it does when I remove these lines. How do I get the container to open and stay open in a specified environment?
My Dockerfile looks like this:
