Create Simple VPG using PowerShell and API

Can someone post a simple template script for creating a new VPG.  I am just looking to get the understanding on getting the first one deployed using the API.  I am just looking for a simply start that gets one created successfully.  I have reviewed the API whitepaper and it is a little overwhelming at first.  I would using this to tweak some of the defaults after I get the first one created.  It would be great if variables can be defined for, names, networks, datastores, etc..

I have reviewed the Zerto Virtual Replication RESTful APIs doc and what I am looking for is a base script like Example 2: Perform an action on page 24.  Instead of reading a CSV file with VMs, just define parameters with the VM name and other VPG properties.

Hi Dave

I’ve experienced the same issue. Starting with creating a VPG with the API can be frustrating. I’ve created a powershell script which just creates a almost fully populated JSON which you then can use to create a VPG.

It uses PSCustomObject for structure and filling in the data. I think it is easier to debug with PSCustom Objects than a raw JSON.

Please note that you have to replace most properties which ends with “Identifier” with your own.

#---------------------------------------------------------[Initialisations]--------------------------------------------------------

# ZVM Server
$ZVMServer = "zvm.lab.local"

# Get Credentials for ZVM API
$Credentials = Get-Credential -Message "Please enter Username and Password for ZVM $($ZVMServer)" -UserName $env:USERNAME
$username = $Credentials.UserName
$password = $Credentials.GetNetworkCredential().Password

#-----------------------------------------------------------[Functions]------------------------------------------------------------

function getxZertoSession ($zvm, $userName, $password) {
    $xZertoSessionURL = $zvm+"session/add"
    $authInfo = ("{0}:{1}" -f $userName,$password)
    $authInfo = [System.Text.Encoding]::UTF8.GetBytes($authInfo)
    $authInfo = [System.Convert]::ToBase64String($authInfo)
    $headers = @{Authorization=("Basic {0}" -f $authInfo)}
    $body = '{"AuthenticationMethod": "1"}'
    $contentType = "application/json"
    $xZertoSessionResponse = Invoke-WebRequest -Uri $xZertoSessionURL -Headers $headers -Method POST -Body $body -ContentType $contentType
    return @{"x-zerto-session"=$xZertoSessionResponse.headers.get_item("x-zerto-session")}
}

#-----------------------------------------------------------[Execution]------------------------------------------------------------

# Build Zerto REST API Url
$ZertoRestURL = "https://$($ZVMServer)/v1/"

# Get Zerto Session Header for Auth
$ZertoSession = getxZertoSession "$($ZertoRestURL)" $username $password

Thanks Tobias, I will give it a shot and let you know.
