Oct 1, 2025October 2025 monthly summary for deckhouse/deckhouse: Delivered two critical robustness fixes that enhance production reliability for vSphere users. Key outcomes: (1) vSphere Cloud Provider Discovery Hook Fix — merged discovery data to ensure configuration values are combined correctly and provider-specific discovery information is integrated, reducing misconfigurations. Commit: 349727c1114185e0b51a152e84ac885b12528ddf. (2) Device Path Calculation Robustness — replaced the previous VM/disk lookup with an MD5-based target string derived from the disk UID, improving accuracy and resilience to VM changes. Commit: b5c1b6aeae6f1cab86607ca6b123204ebb242df5. Impact: higher reliability, fewer support incidents related to cloud provider setup and device path resolution. Technologies/skills demonstrated: Go backend fixes, cloud-provider integration, hashing/UID-based identification, provider-specific discovery handling.
