Function Install-AzureKubeCLI { <# .SYNOPSIS Installs `kubectl` and `kubelogin` if they are not already installed on the system. .DESCRIPTION The `Install-AzureKubeCLI` function checks if both `kubectl` and `kubelogin` are installed on the system by attempting to retrieve their version information. If either tool is missing, the function uses the Azure CLI (`az`) to install both tools via `az aks install-cli`. If both tools are already installed, their version information is displayed. .EXAMPLE Install-AzureKubeCLI This command checks for the installation of both `kubectl` and `kubelogin`. If they are not found, it installs them using the Azure CLI. If they are already installed, it prints their current version. .NOTES Author: Michiel Van Haegenborgh Requires: Azure CLI (`az`) to be installed on the system for installing `kubectl` and `kubelogin`. This function assumes that `az aks install-cli` will be used to manage the Kubernetes CLI tools. .LINK https://kubernetes.io/docs/tasks/tools/ Learn more about `kubectl` and how it is used to manage Kubernetes clusters. .LINK https://github.com/Azure/kubelogin Learn more about `kubelogin`, a tool for Azure Kubernetes Service (AKS) authentication. #> # TODO: Auto install az cli if not installed # Check if az command is available without producing an error if not found if (-not (Get-Command az -ErrorAction SilentlyContinue)) { Write-Host "Azure CLI is not installed.
