This change prevents unbounded memory growth in long-running processes by implementing a bounded LRU cache for ECR credentials with the following features: - Bounded cache size (default: 100 entries) to prevent memory leaks - TTL-based expiration (default: 6 hours) to ensure credential freshness - Thread-safe operations for concurrent access - Graceful fallback to unbounded cache if bounded cache creation fails - Comprehensive test coverage including unit and integration tests The implementation uses hashicorp/golang-lru/v2 for the LRU cache and wraps the existing ECR credential helper to maintain compatibility while adding memory safety.
