Bug Fixes¶

• Fix DNS records not being deleted when instances are terminated
• The get_instance_ip() function now properly falls back to instance tags when the IP address is None during instance termination
• Resolves issue where orphaned DNS records remained in Route53 after manual instance termination
• Adds integration test test_dns_record_deletion_on_manual_termination to verify proper DNS cleanup
• Update test suite to use pytest-infrahouse subzone fixture
• Replace test_zone data source lookup with direct zone_id variable

Refactor¶

• Remove custom Lambda packaging infrastructure (lambda_code.tf)
• Remove package_update_dns.sh script
