KB:Kubernetes Operators

 Kubernetes Operators are software extensions that use custom controllers to manage complex, stateful applications on Kubernetes. They follow the controller pattern—constantly observing the cluster’s current state and reconciling it with the desired state as defined by a Custom Resource (CR).

Operators are typically used to automate:

  • Installation and configuration

  • Scaling and updates

  • Backups, failovers, and recovery

  • Application-specific lifecycle management

They are not part of the Kubernetes core control plane, but they integrate tightly with it using Kubernetes-native APIs and resources. Operators encapsulate human operational knowledge into code, enabling advanced automation beyond what built-in controllers offer.

KB: Azure ACA Container fails to start (no User Assigned or Delegated Managed Identity found for specified ClientId)

Image
When deploying secure workloads using Azure Container Apps (ACA) , teams often face confusion between User Assigned Managed Identities (UAMI) and App Registrations . While both entities are visible in Azure Active Directory and have similar identifiers (Application ID, Object ID), they serve very different purposes . This confusion can lead to authentication failures when accessing services like Azure App Configuration or Key Vault . A common issue occurs when a container app is configured with a managed identity, but the environment variables or role assignments mistakenly reference an App Registration instead, causing errors like: "No User Assigned or Delegated Managed Identity found for specified ClientId" This article breaks down the difference between UAMI and App Registrations, explains why this issue happens, and outlines the correct approach to resolve it. Symptoms Azure Container App fails to authenticate to Azure App Configuration or other services. Logs...

Electron Process Execution Failure with FSLogix

  Technical Note: Electron Process Execution Failure with FSLogix 1. Overview When running Electron-based applications in environments using FSLogix Profile or Office Containers , users may encounter issues where the Electron process fails to launch or execute properly . This behavior has been observed in Azure Virtual Desktop (AVD) , Windows Virtual Desktop (WVD) , and other environments where FSLogix filter drivers are active. 2. Symptoms Electron-based applications (e.g., desktop apps built on Electron, CLI wrappers) do not start , remain unresponsive, or terminate silently. No visible logs or error messages are generated by the application. Standard executables run correctly when placed outside of the FSLogix-controlled profile path (e.g., copying to C:\Temp allows execution). The issue is reproducible across all Electron apps in the FSLogix-managed profile. 3. Root Cause The issue is linked to FSLogix filter drivers ( frxdrv , frxdrvvt , frxccd ) interfe...
