/**
|
|
* Zero-Downtime Rolling Restart Orchestrator
|
|
*
|
|
* Purpose: Safely restart production services with health checks, rollback, and event emission
|
|
*
|
|
* Features:
|
|
* - Pre/post-restart health validation
|
|
* - Dependency-aware restart ordering
|
|
* - Automatic rollback on failure
|
|
* - Event emission for dashboard visibility
|
|
* - Database migration execution
|
|
* - Graceful systemd reload with grace periods
|
|
* - Dry-run support for testing
|
|
* - Force mode for emergency operations
|
|
*
|
|
* Usage:
|
|
* pnpm restart:rolling # Restart all services
|
|
* pnpm restart:rolling --service sso.api # Restart single service
|
|
* pnpm restart:rolling --dry-run # Preview without executing
|
|
* pnpm restart:rolling --force # Skip health checks (emergency)
|
