NextPVR/Docker on a RPi 5

[magix]

Hi,

thank you very much for your fast reply! I am running multiple docker containers on the same server and to ensure that they do not interfere, and to make it easy to swap devices, quick upgrading and so on, I want to use Docker. Any hope to get help to get it running sooner, or should I wait for the next release?
Is the Dockerfile for 32bit open source? Where would I find it?

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....
