# Daily beta build: build Docker image, push to registries, create/update GitHub prerelease
#
# Usage:
#   ./docker-publish-daily-beta.sh [--parallel] [--ghcr-only] [--dockerhub-only] [--skip-release]
#
# Examples:
#   ./docker-publish-daily-beta.sh                  # Full daily beta workflow
#   ./docker-publish-daily-beta.sh --parallel       # Build both archs simultaneously
#   ./docker-publish-daily-beta.sh --ghcr-only      # Only push to GHCR
#   ./docker-publish-daily-beta.sh --dockerhub-only # Only push to Docker Hub
#   ./docker-publish-daily-beta.sh --skip-release   # Build+push without GitHub release
#
# Reads APP_VERSION from backend/app/core/config.py (must be a beta version like 0.2.2b1).
# Builds and pushes a multi-arch Docker image tagged as 'daily'. Each push overwrites the
# previous 'daily' image. A GitHub prerelease is created with a date-stamped tag for history.
#
# Users can stay up to date by pulling the 'daily' tag or using Watchtower:
#   docker pull ghcr.io/maziggy/bambuddy:daily
#
# Prerequisites:
#   1. Log in to ghcr.io:
#      echo $GITHUB_TOKEN | docker login ghcr.io -u YOUR_USERNAME --password-stdin
#
#   2. Log in to Docker Hub:
#      docker login -u YOUR_USERNAME
#
#   3. GitHub CLI (gh) authenticated for creating releases
#
# Supported architectures:
#   - linux/amd64 (x86_64, most servers/desktops)
#   - linux/arm64 (Raspberry Pi 4/5, Apple Silicon via emulation)
