Provisioning a Virtual Machine on Azure
This post will help you setup a CentOS 7.1 Virtual Machine on Azure using Azure Resource Manager (ARM) and PowerShell.
1) Finding a CentOS VM Image
Using our favorite PowerShell tools, we can discover details about pre-built CentOS 7.1 Azure Virtual Images.
Switch-AzureMode -Name AzureResourceManager
$location = 'eastus'
Get-AzureVMImagePublisher -Location $location
$publisherName = 'OpenLogic'
Get-AzureVMImageOffer -Location $location `
-PublisherName $publisherName
$offer = 'CentOS'
Get-AzureVMImageSku -Location $location `
-PublisherName $publisherName `
-Offer $offer `
| Select-Object -Property 'Skus'
$sku = '7.1'
Get-AzureVMImage -Location $location `
-PublisherName $publisherName `
-Offer $offer `
-Skus $sku
$verison = '7.1.20150731'
Get-AzureVMImage -Location $location `
-PublisherName $publisherName `
-Offer $offer `
-Skus $sku `
-Version $verison
2) Creating The ARM Template
We can use the CentOS Virtual Image information to create a CentOS 7.1 Standard_A1 Virtual Machine Template. Name this file DeploymentTemplate.json.

3) Provisioning a CentOS Virtual Machine
Prepare the Template Parameter File with the template’s parameter values. Name this file DeploymentTemplate.param.dev.json.
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"newStorageAccountName": {
"value": "mslinuxbrisebois"
},
"adminUsername": {
"value": "brisebois"
},
"dnsNameForPublicIP": {
"value": "briseboisdns"
}
}
}
Then deploy the Azure Resource Manager Template and Parameters using PowerShell.
New-AzureResourceGroup -Name 'mslinuxbrisebois' `
-Location 'eastus' `
-TemplateFile 'DeploymentTemplate.json' `
-TemplateParameterFile 'DeploymentTemplate.param.dev.json' `
-Force -Verbose
