Dockerfile

# Dockerfile for HDHomeRun DVR
# The initial container will create a base Alpine Linux image and install
# runtime script which will download the latest record engine, configure it
# if no config already exists and then start the engine.
# To update the record engine, simply stop the container, and restart

# FROM alpine: 3.20.2 (as of 08/19/2024)
# changed to latest tag for periodic automatic updates
FROM alpine:latest as builder
