The PowerShell script that can be used to download latest version of Istio analogus to https://git.io/getLatestIstio

getLatestIstio.ps1

param(
    [string] $IstioVersion = "0.3.0"
)

$url = "https://github.com/istio/istio/releases/download/$($IstioVersion)/istio_$($IstioVersion)_win.zip"
$Path = Get-Location
$output = [IO.Path]::Combine($Path, "istio_$($IstioVersion)_win.zip”)
    
Write-Host "Downloading Istio from $url to path " $Path -ForegroundColor Green 
    
#Download file
(New-Object System.Net.WebClient).DownloadFile($url, $output)
    
# Unzip the Archive
Expand-Archive $output -DestinationPath $Path
    
#Set the environment variable
$IstioHome = [IO.Path]::Combine($Path, "istio-$($IstioVersion)")
    
[Environment]::SetEnvironmentVariable("ISTIO_HOME", "$IstioHome", "User")

This is my updated working script for the latest version (as today):

param(
    [string] $IstioVersion = "1.2.5"
)

$url = "https://github.com/istio/istio/releases/download/$($IstioVersion)/istio-$($IstioVersion)-win.zip"
$Path = Get-Location
$output = [IO.Path]::Combine($Path, "istio-$($IstioVersion)-win.zip")
    
Write-Host "Downloading Istio from $url to path " $Path -ForegroundColor Green 
    
#Download file
(New-Object System.Net.WebClient).DownloadFile($url, $output)
    
# Unzip the Archive
Expand-Archive $output -DestinationPath $Path
    
#Set the environment variable
$IstioHome = [IO.Path]::Combine($Path, "istio-$($IstioVersion)")
    
[Environment]::SetEnvironmentVariable("ISTIO_HOME", "$IstioHome", "User")
