# Recent logs
ssh echonest-droplet 'docker compose -f /opt/andre/docker-compose.yaml logs --tail=50 andre'

# Follow logs (use timeout to avoid hanging)
ssh echonest-droplet 'timeout 10 docker compose -f /opt/andre/docker-compose.yaml logs -f --tail=20 andre'

# Redis logs
ssh echonest-droplet 'docker compose -f /opt/andre/docker-compose.yaml logs --tail=20 redis'

# Player worker logs
ssh echonest-droplet 'docker compose -f /opt/andre/docker-compose.yaml logs --tail=20 player'

Restart Services

# Restart all
ssh echonest-droplet 'cd /opt/andre && docker compose restart'

# Restart specific service
ssh echonest-droplet 'cd /opt/andre && docker compose restart andre'
ssh echonest-droplet 'cd /opt/andre && docker compose restart player'
ssh echonest-droplet 'cd /opt/andre && docker compose restart redis'

Deploy Code Updates

# 1. Sync code from local repo to server
rsync -avz --exclude='.git' --exclude='__pycache__' --exclude='*.pyc' \
  --exclude='.env' --exclude='local_config.yaml' --exclude='.cache' \
  ~/repos/andre/ echonest-droplet:/opt/andre/

# 2. Rebuild and restart
ssh echonest-droplet 'cd /opt/andre && docker compose up -d --build'

# 3. Verify
ssh echonest-droplet 'docker compose -f /opt/andre/docker-compose.yaml ps'
curl -s https://echone.st/health

Note: Always confirm with Dylan before deploying.

Redis Operations

# Check Redis memory usage
ssh echonest-droplet 'docker exec andre_redis redis-cli -a \$REDIS_PASSWORD INFO memory 2>/dev/null | grep used_memory_human'

# Trigger Redis backup
ssh echonest-droplet 'docker exec andre_redis redis-cli -a \$REDIS_PASSWORD BGSAVE 2>/dev/null'

# Count Redis keys
ssh echonest-droplet 'docker exec andre_redis redis-cli -a \$REDIS_PASSWORD DBSIZE 2>/dev/null'

Server Resource Usage

ssh echonest-droplet 'df -h / && echo --- && free -m && echo --- && docker stats --no-stream'

Architecture

• Server: DigitalOcean Droplet (192.81.213.152, NYC1, $6/mo)
• Reverse Proxy: Caddy (auto HTTPS via Let's Encrypt)
• Services: Flask app (port 5001), Background worker (master_player.py), Redis 7
• Source Code: ~/repos/andre/ (local), /opt/andre/ (server)
• Network: Redis is internal-only (Docker network); not exposed to internet
• SSH Host: echonest-droplet (configured in ~/.ssh/config, uses deploy key)
• Tailscale: 100.92.192.62 (backup SSH access, bypasses fail2ban)

Notes

• All REST API queue endpoints are public (no auth cookies needed)
• email=${ECHONEST_EMAIL} from the protected cache should be used as the user identifier for API calls
• Music sources: Spotify, YouTube, SoundCloud (podcasts also supported)
• Search always goes through Spotify's API
• The Bender auto-fill engine automatically queues songs when the queue runs low
• Always confirm with Dylan before deploying code or restarting services
• Vote, skip, remove, pause, and clear queue are available via token-authenticated REST API (see Managing Queue section)
