Month: 2025-09 — Summary: Focused enhancement in the castai/helm-charts repository to improve deployment identification, reliability, and alignment with Kubernetes conventions for the dbo-collector. Implemented standard Kubernetes labels (app.kubernetes.io/name and app.kubernetes.io/component) on the dbo-collector deployment, bumped the Helm chart version to reflect the changes, and ensured long resource names are handled safely by truncating the name label to 63 characters. These changes reduce deploy-time errors, improve observability, and simplify multi-cluster management. Commit references included: 55ee31c82178fc3c41a6bcfb7bd66e302348a660 and 73397d5eee739a5b4e8d9fc4c9415178e835fda3.
