CentOs-Azure

Creating a CentOS VM Using ARM

Docker and Open Source projects are getting lots of attention, so I decided that it was time for me to build a Linux Virtual Machine on Microsoft Azure. This post is all about creating an Azure Resource Manager Template for a CentOS Virtual Machine with two stripped Data Disks. This template should be used as a starting point and may require some tweaking to meet your needs. Feel free to share your thoughts by using the comment section.

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 = 'westus'

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 = '7.1.201504'

Get-AzureVMImageDetail -Location $location `
                       -PublisherName $publisherName `
                       -Offer $offer `
                       -Skus $sku `
                       -Version $verison

Building the ARM Template

Starting from the Ubuntu Template in Visual Studio we can use the CentOS Virtual Image information, found in the previous section of this post, to create a CentOS 7.1 Standard_A3 Virtual Machine. To regroup the data disks as a RAID0 volume we can use the Create Ubuntu vm data disk raid0 template as a guide. Then we can make small changes to reach our goal.

Publishing the ARM Template

Prepare the Template Parameter File

{
    "$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.

                      -CurrentStorageAccountName 'briseboispackages'

This template will use the following script inspired by vm-disk-utils-0.1.sh for Ubuntu to create a RAID0 out of all the unformated data disks. A small modification has been applied for this to work on CentOS.

# Description:
#  This script automates the partitioning and formatting of data disks
#  Data disks can be partitioned and formatted as seperate disks or in a RAID0 configuration
#  The scrtip will scan for unpartitioined and unformatted data disks and partition, format, and add fstab entries
# Parameters :
#  1 - b: The base directory for mount points (default: /datadisks)
#  2 - s  Create a striped RAID0 Array (No redundancy)
#  3 - h  Help 
# Note : 
# This script has only been tested on CentOS 7.1 and must be root
