1.2.3 (2025-07-02)

⚠️ CRITICAL: This version contains a webhook configuration bug that prevents proper resource metadata collection. Please upgrade to version 1.2.5 immediately.

Release 1.2.3 introduces Cloud Service Provider Auto-Detection, significant Performance Optimizations for the admission controller, enhanced Istio Integration, and numerous reliability improvements. This release dramatically simplifies deployment configuration while improving performance and compatibility with service mesh environments.

Key Features

  • Cloud Service Provider Auto-Detection: The CloudZero agent now includes a comprehensive "scout" system that automatically detects cloud environment metadata including provider, region, account ID, and cluster name. This eliminates the need to manually configure these values in many deployments.
    • AWS Support: Automatically detects region, account ID from EC2 instance metadata
    • Google Cloud Support: Automatically detects region, project ID, and cluster name from GCE metadata
    • Azure Support: Automatically detects region and subscription ID from Azure IMDS
  • Webhook Server Optimization: The webhook server now explicitly requests only the Kubernetes resource types it needs instead of receiving all resources, significantly reducing network traffic and improving performance.
  • Enhanced Istio Integration: The webhook server now automatically includes sidecar.istio.io/inject: "false" annotation by default, providing seamless out-of-the-box compatibility with Istio service mesh environments without requiring manual configuration.

Additional Enhancements

  • Improved Load Balancing: Enhanced webhook server connection handling with periodic connection rotation to ensure proper load distribution across service replicas in multi-replica deployments.
  • Configurable Webhook Timeout: Added ability to configure webhook admission controller timeout values, and changed the default from 15 seconds to 1 second.
  • Enhanced Pod Disruption Budget (PDB) Configuration: Completely reworked PDB validation and override behavior to prevent common configuration errors and provide more intuitive component-level overrides.

Upgrade Steps

To upgrade to version 1.2.3, run the following command:

helm upgrade --install <RELEASE_NAME> cloudzero/cloudzero-agent -n <NAMESPACE> --create-namespace -f configuration.example.yaml --version 1.2.3
