  • Implements retry logic with a configurable timeout.
  • Ensures that maintenance tasks are executed only when the system is in a safe state.

Purpose

The primary purpose of this role is to safeguard system stability during maintenance by preventing conflicts with running services. It ensures that maintenance operations proceed only when the environment is ready.

Features

  • Service Locking: Blocks maintenance tasks until critical services are stopped.
  • Timeout and Retry Logic: Configurable wait times and maximum attempts.
  • Conflict Avoidance: Prevents interference between maintenance operations and running services.
