Bias Analysis

Detected Bias Types

windows_first
missing_linux_example
windows_tools
Summary
The documentation is heavily biased toward Windows environments. All command-line examples use PowerShell, and Windows-specific tools and paths (e.g., C:\ paths, PowerShell cmdlets) are used exclusively. There are no Linux shell or cross-platform command examples, and instructions for Linux or macOS clients are missing or not prioritized. The workflow assumes a Windows client, and Linux alternatives (such as bash commands, Linux file paths, or Linux-native tools) are not mentioned.
Recommendations
  • Provide equivalent Linux/bash shell command examples alongside PowerShell commands for all device and Kubernetes interactions.
  • Include instructions for saving kubeconfig files in Linux/macOS home directories (e.g., ~/.kube/config) as well as Windows paths.
  • Mention and demonstrate the use of cross-platform tools (e.g., kubectl, ssh) in both Windows and Linux contexts.
  • Clarify in the prerequisites and throughout the guide that both Windows and Linux clients are supported, and provide OS-specific notes where necessary.
  • Where PowerShell cmdlets are used (e.g., Get-HcsGpuNvidiaSmi, New-HcsKubernetesUser), specify if Linux equivalents exist or provide alternative instructions for Linux users.
  • Show example outputs from Linux terminals as well as Windows PowerShell to ensure parity and inclusivity.
