🏗️ Technical Implementation

Code Structure

Added Constants (utils/constants.ts):

export const API_ENDPOINTS = {
  // ... existing endpoints
  MYSQL_STATUS: (clusterId: number, serverId: number) =>
    `clusters/${clusterId}/servers/${serverId}/managed/mysql`,
  MYSQL_RESTART: (clusterId: number, serverId: number) =>
    `clusters/${clusterId}/servers/${serverId}/managed/mysql/actions/restart`,
  MYSQL_DATABASES: (clusterId: number, serverId: number) =>
    `clusters/${clusterId}/servers/${serverId}/managed/mysql/databases`,
  MYSQL_DATABASE: (clusterId: number, serverId: number, databaseId: string) =>
    `clusters/${clusterId}/servers/${serverId}/managed/mysql/databases/${databaseId}`,
};

export const SERVICES = {
  // ... existing services
  MYSQL: "MySQL/MariaDB",
};

Handler Methods (index.ts):

  • handleMysqlStatus() - Status retrieval and formatting
  • handleMysqlRestart() - Service restart
  • handleMysqlCreateDatabase() - Database creation with description
  • handleMysqlListDatabases() - Database listing
  • handleMysqlDeleteDatabase() - Database deletion

Zod Schemas:

  • ClusterOperationSchema - Reused for status/restart/list
  • DatabaseCreateSchema - Extends base with optional description
  • DatabaseDeleteSchema - Extends base with required database_id

Error Handling

Comprehensive error handling for:

  • Invalid cluster/server
  • Authentication failures
  • API communication errors
  • Missing data in responses
  • Service unavailability

All errors include:

  • Descriptive error messages
  • Context about the operation
  • Original error information
  • Proper cleanup of temporary files

Logging

Console logging at key points:

  • Operation start (with params)
  • API calls
  • Success confirmation
  • Error details

🚀 Next Steps

Stage 3: Redis Management Tools

Next implementation phase will add:

  • redis_status
  • redis_create_cache_instance
  • redis_create_session_instance
  • redis_create_fpc_instance
  • redis_start_instance
  • redis_stop_instance
  • redis_flush_instance

Future Enhancements (Out of Scope)

  • SQL dump import (workaround: manual or SSH)
  • Manual user creation (auto-created with database)
  • Database backup/restore
  • Query execution
  • Performance metrics

📝 API Limitations Identified

No SQL Import Endpoint

Issue: MaxCluster API doesn't expose SQL import functionality Impact: Cannot automatically import Magento sample data Workaround:

  • Provide connection details for manual import
  • Use SSH access if available
  • Document manual import process

Auto-Generated Credentials Only

Issue: Cannot specify custom database name/username/password Impact: Less control over naming conventions Benefit: More secure (random generation) Mitigation: Use description field for identification

🎉 Stage 2 Complete

MySQL/MariaDB management is now fully operational for Magento 2 cluster control. All critical database operations are supported, enabling automated Magento 2 demo provisioning.

Status: ✅ READY FOR STAGE 3 (Redis Management) Build Status: ✅ PASSING Integration: ✅ READY FOR MAGENTO 2
