Coolify Zero - Zero-Downtime Deployment Manager

Docker-native failover system eliminating deployment downtime for Coolify services. Automated hot standby containers with Traefik health check integration maintain service availability during deployments.

Impact

Eliminated deployment downtime: Zero downtime vs. 1-2 minute service interruption during updates
Automatic failover: Hot standby containers maintain service during primary deployment
Zero configuration: Works with Coolify's existing deployment flow without modification
Self-healing: Manager automatically recovers from any state, recreating failover containers as needed

Key Features

Hot standby system: Maintains failover containers synced with primary service version
CLI management: Simple enable/disable commands with real-time status monitoring
Traefik integration: Automatic health-based traffic routing during deployments
Version tracking: Syncs failover containers after successful primary deployments
