NextPVR/Docker on a RPi 5

[sub]

I am trying something like this, but struggling with the Entrypoint. What should I choose as Entrypoint?

It basically ends up running:

Code:

dotnet NextPVRServer.dll

Following works just fine for me on a Raspi 5 with a TV Butler 100TC USB tuner. 

Dockerfile: 

Code:

# Use Debian as the base image FROM debian:bullseye # Set environment variables ENV DEBIAN_FRONTEND=noninteractive # Update and install dependencies RUN apt-get update && \     apt-get install -y curl; \     \     # Download NextPVR latest version     curl https://nextpvr.com/nextpvr-helper.deb -O; \     dpkg-deb -R nextpvr-helper.deb extracted_pkg; \     rm extracted_pkg/DEBIAN/postinst; \     dpkg-deb -b extracted_pkg modified_package.deb; \     apt-get install -y ./modified_package.deb --install-recommends; ENV PATH="$PATH:/opt/nextpvr/system" # Expose necessary ports EXPOSE 8866 # Set default command CMD ["/opt/dotnet/dotnet", "/opt/nextpvr/system/NextPVRServer.dll"]

docker-compose.yaml

Code:

--- services:   nextpvr:     build:       context: .     container_name: nextpvr     volumes:       - ./config:/config       - /mnt/nas/Video/TV-Recordings/:/recordings       - ./buffer:/buffer     ports:       - 8866:8866     devices:       - /dev/dri:/dev/dri #optional       - /dev/dvb:/dev/dvb #optional     restart: unless-stopped     environment:       NEXTPVR_DATADIR_USERDATA: /config/

Challenges I faced: 

• Debian bookworm is not supported, using bullseye works fine
  
• nextpvr-helper.deb relies on having systemd running - which doesn't make sense in Docker
  removing `postinst` from .deb package fixes the issue 
  
• /opt/nextpvr/system needs to be added to $PATH in order that scanning for channels works 
  

Hope that helps someone

Why would you use the deb file in a Docker none of your statements are correct running natively or running the Docker image.

He's building his own docker container rather than using the released container - which is a valid (if unsupported here) approach. If I were building my own Docker container - I'd consider using the official zip distribution rather than a deb file, but potato potato....
