Add go2rtc-beta Home Assistant addon

[Copilot]

Adds a new go2rtc-beta addon built from the beta branch of skrashevich/go2rtc, mirroring the double-take / double-take-beta pattern already in the repo.

New files: go2rtc-beta/

• config.yaml — slug go2rtc-beta, image ghcr.io/skrashevich/hassio-addon-go2rtc-beta-{arch}, ingress on 1984, ports 1984/8554/8555 (tcp+udp), log_level schema, config:rw map
• Dockerfile — three-stage build:
  • build: cross-compiles go2rtc binary from skrashevich/go2rtc@beta using golang:1.26-alpine
  • download-cdn: independently clones the repo to run download_cdn.sh for offline web UI assets — fixes the logical error in the spec where COPY --from=build /src/... referenced source paths that never exist in the build stage (only the compiled binary does)
  • final: alpine:3.21 + s6-overlay 3.1.6.2 + bashio v0.14.3; run.sh bootstraps /config/go2rtc.yaml on first start using bashio::config
• README.md / CHANGELOG.md — standard addon docs

Original prompt

Задача

Добавить новый Home Assistant addon go2rtc-beta в репозиторий skrashevich/hassio-addons, основанный на ветке beta репозитория skrashevich/go2rtc.

Контекст

Репозиторий уже содержит аддоны с похожей структурой:

• double-take/ — стабильная версия
• double-take-beta/ — бета-версия с суффиксом -beta

Нужно создать аналогичную пару: аддон go2rtc-beta (beta-ветка go2rtc).

Структура репозитория go2rtc (ветка beta)

• Собирается из исходников Go (main.go, go.mod)
• Docker-образ строится через docker/Dockerfile (multi-stage: build → download-cdn → final alpine+python образ)
• Порты: 1984 (HTTP/WebUI), 8554 (RTSP), 8555 (WebRTC/TCP), 8555/udp (WebRTC/UDP)
• Конфиг монтируется в /config
• Точка входа: /usr/local/bin/entrypoint.sh
• Поддерживаемые архитектуры: amd64, aarch64, armv7

Что нужно создать

Создать директорию go2rtc-beta/ со следующими файлами:

1. go2rtc-beta/config.yaml

name: go2rtc (Beta)
version: "beta"
url: https://github.com/skrashevich/go2rtc
description: Ultimate camera streaming application with support RTSP, WebRTC, HomeKit, FFmpeg, RTMP, etc. (Beta branch)
panel_icon: mdi:cctv
slug: go2rtc-beta
arch:
  - amd64
  - aarch64
  - armv7
startup: application
boot: auto
ingress: true
ingress_port: 1984
init: false
full_access: false
ports:
  1984/tcp: 1984
  8554/tcp: 8554
  8555/tcp: 8555
  8555/udp: 8555
ports_description:
  1984/tcp: go2rtc WebUI / HTTP API
  8554/tcp: RTSP server
  8555/tcp: WebRTC / PCMU+PCMA TCP
  8555/udp: WebRTC / PCMU+PCMA UDP
map:
  - config:rw
options:
  log_level: info
schema:
  log_level: list(trace|debug|info|warn|error)
image: ghcr.io/skrashevich/hassio-addon-go2rtc-beta-{arch}

2. go2rtc-beta/Dockerfile

Dockerfile должен:

1. Клонировать или использовать образ из ветки beta репозитория skrashevich/go2rtc
2. Установить s6-overlay (аналогично другим аддонам в репозитории)
3. Установить bashio
4. Добавить скрипт запуска /run.sh, который читает конфиг через bashio и запускает go2rtc
