* Fix: Move S3 backup to BEFORE stopping old server Critical fix: The old server may wipe games.e0es on shutdown if it doesn't have the save() merge fix. The backup must happen BEFORE stopping to capture valid data. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * Admin console shows all games, auto-install s3cmd, restart nginx properly 1. Admin console now shows all games from games.e0es, not just loaded ones: - Added getAllRunningGamesSummary() to GamesManager - Updated getRunningGames() to include unloaded games with "[Not loaded]" status - Clicking into a game triggers lazy loading via getGameHistory() 2. Deploy script improvements: - Auto-install s3cmd if not present (via pip or apt) - Auto-configure s3cmd for DigitalOcean Spaces from .env - Use nginx restart instead of reload to ensure all workers pick up new config 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

# Blue-Green Deployment Script for Eagle Server
|
|
#
|
|
# This script performs a zero-downtime deployment by:
|
|
# 1. Starting the new version on a staging port (green)
|
|
# 2. Waiting for it to become healthy
|
|
# 3. Running warmup traffic to pre-heat the JIT
|
|
# 4. Stopping the old version (blue) - which flushes state to storage
|
|
# 5. Switching nginx to route traffic to green
|
|
# 6. Users reconnect, triggering lazy game loading from fresh storage
|
|
# 7. Cleaning up
|
|
#
|
|
# Usage: ./deploy-blue-green.sh [NEW_IMAGE_TAG]
|
|
#
|
|
# Example:
|
|
# ./deploy-blue-green.sh latest
|
|
# ./deploy-blue-green.sh sha-abc123
|
|
#
