Hangar Release 2025_07 – Stay Up to Date with Kubernetes Cluster Management Enhancements

Nodepool Management Upgrade

We have fundamentally improved nodepool management to ensure better scalability and clarity. The new cache mechanism via Informer reduces the load on the Kubernetes API and significantly improves performance.

Role-based access management

With this version, we are introducing a comprehensive role concept:

  • SuperAdmin: Complete control over all clusters, including creation, deletion and infrastructure management
  • ClusterAdmin: Management of a specific cluster including user management and node scaling
  • ClusterUser: Access to the cluster overview for assigned clusters

Infrastructure Overview

The new Infrastructure Overview provides a comprehensive insight into the Infrastructure Cluster:

  • Display of cluster name and Kubernetes version
  • Status of the control plane components
  • Overview of physical and virtual nodes with status information
  • Warnings for insufficient resources (pending nodes)

Improved user management

The cluster creation and administration has been extended to include functions for user assignment:

  • Direct assignment of users during cluster creation
  • Role selection (admin/user) via a clear interface
  • Subsequent addition and removal of users in the cluster administration

Performance & Stability

Further improvements for a more robust platform:

  • Optimized certificate management for more security
  • Expansion of test coverage for higher quality
  • Various bug fixes for a more stable user experience
