Multi-Service Orchestration
Overview
Multi-service management methodology adapted from the Everything Claude Code project. Handles service discovery, dependency resolution, PM2 management, cascade/parallel execution, and cross-service testing.
Service Discovery
- Scan for service directories (packages/, services/, apps/)
- Parse package.json for dependencies and scripts
- Build dependency graph
- Detect package managers per service
- Determine topological execution order
- Flag circular dependencies
Execution Modes
Cascade Mode
- Sequential execution following dependency order
- Wait for health check before starting dependents
- Stop on failure with detailed error report
- Support partial cascade (skip healthy services)
Parallel Mode
- Concurrent execution for independent services
- Optional worktree isolation per service
- Configurable concurrency limit
- Collect all results (continue on individual failures)
Auto Mode (Default)
- Analyze dependency graph
- Use cascade for services with sequential dependencies
- Use parallel for independent service groups
- Hybrid: cascade between groups, parallel within groups
PM2 Management
- Generate ecosystem.config.js from service manifest
- Configure per service: name, script, cwd, env, instances
- Start in topological order with health check gates
- Log rotation and restart policies
- Status monitoring: online, stopped, errored
Cross-Service Testing
- API contract verification (request/response schemas)
- Event bus message flow testing
- Shared state consistency checks
- Authentication across service boundaries
- Circuit breaker behavior validation
Health Monitoring
- Health check endpoint polling
- PM2 process status monitoring
- Resource usage tracking (CPU, memory)
- Log file error pattern detection
- Inter-service connectivity verification
When to Use
- Multi-package monorepo development
- Microservice orchestration
- Full-stack application management
- CI/CD pipeline for multi-service deployments
