MongoDB Atlas is a database as a service that makes it easy to deploy, manage, and scale MongoDB. So you can focus on innovation, not operations. Brought to you in partnership with MongoDB.

You can currently add Linux Virtual Machines to Windows Azure via the Windows Azure Portal from base OS images of the following distributions: CentOS, SUSE and Ubuntu. But it is then up to you to install and configure any additional software you require.

With the announcement of Microsoft Open Technologies’ VM Depot you now have access to a community-driven catalog of preconfigured operating systems, applications, and development stacks that can easily be deployed on Windows Azure.

What do we need to get started ?

The help on VM Depot indicates that the Windows Azure command line tool is the mechanism to use when deploying images from VM Depot to Windows Azure. This tool is available for Mac and Linux but I wanted to deploy from my Windows machine. The only command line tools available for Windows via the Windows Azure Tools Download page are the Windows Azure Powershell cmdlets which do not support the new community virtual machine image switch.

Thankfully I happened across Sandrino Di Mattia’s post Using the Windows Azure CLI on Windows and from within Visual Studio which was exactly what I was after.

So – if you are doing the deployment from a Mac or Linux box download the command line tool from the Windows Azure website. If you are doing the deployment from a Windows box continue reading to install the Windows version of the command line tool. All steps after this installation will work for all platforms since we will be leveraging a common tool.

Download the command line tools for windows and install.

Windows Azure Command Line Tools Setup

This will install the tools to the following location and configure your PATH environment variable.

Installation Location

Firing up a Command Prompt and typing azure will provide usage information for the command line tool.

Azure CLI command prompt

Typing the following at the command line shows that the option we require for creating a virtual machine from a community image is available in the Windows version of the command line tool.

azure vm create --help

Azure CLI vm create with community option

Now we are ready to begin.

Configuring the command line tool

As with all the Windows Azure tools, we’ll need to ensure our management certificates are configured in the tool so that we can interact with the Windows Azure management services.

Type the following at the command line to download your publishsettings file.

azure account download

This file contains all the information for your subscriptions and management certificates. This command will fire up a browser and will require you to authenticate with your Windows Azure credentials if you are not currently logged in. The publishsettings file will then be downloaded.

Azure CLI download publish settings

Once the file has downloaded, type the following at the command line, replacing $FILENAME with the path to the publishsettings file just downloaded. You can see that mine was downloaded to C:\Users\Paul\Downloads\.

azure account import "$FILENAME"

Azure CLI import publish settings

You can see that I have 2 subscriptions, a personal subscription and an MSDN subscription. Next we’ll set the subscription that we wish to work with when creating our virtual machine.

Type the following at the command line, replacing $SUBSCRIPTION with your subscription name. You can see that I have selected my MSDN subscription.

azure account set "$SUBSCRIPTION"

Azure CLI set account

Selecting a VM from the catalog

I selected the Solr 4.0.0-0 (Ubuntu 12.10) image from the catalog available on VM Depot and clicked on the Deployment Script button at the top of the page.

VM Depot Solr 4.0.0 (Ubuntu 12.10) Image

After selecting the Deployment Region from the drop down, I was presented with a command line script to create my Solr virtual machine. Keep this handy.

azure vm create DNS_PREFIX -o vmdepot-30-1-1 -l "West US" USER_NAME [PASSWORD] [--ssh] [other_options]

Create a storage account

We’ll need to create a storage account that hold the virtual machine’s OS Disk (vhd). Type the following at the command line, replacing $REGION with the data centre region you have selected and $VMNAME with the dns name you are giving your virtual machine.

azure account storage create --location "$REGION" "$VMNAME"

Azure CLI create storage account for image and vhd

You can see that I have chosen the West US as my region and pbsolr4 as the dns name for my virtual machine. You can also confirm the creation of the storage account in the portal.

Portal - verify storage account created

To ensure that this storage account is used for your virtual machine, set it as the default storage account for the interactions to follow on the command line.

Type the following at the command line, replacing $STORAGEACCOUNT with the name of your storage account. You can see that my storage account name is pbsolr4.

azure config set defaultStorageAccount "$STORAGEACCOUNT"

Azure CLI set storage account as default

Creating the VM

We’ll now use that command line script that the VM Depot site gave us to run as a deployment script. I’ll repeat it here.

azure vm create DNS_PREFIX -o vmdepot-30-1-1 -l "West US" USER_NAME [PASSWORD] [--ssh] [other_options]

I ran the command line script with an additional parameter –vm-size small to specify my virtual machine size. My complete command line script is as follows:

azure vm create pbsolr4 -o vmdepot-30-1-1 -l "West US" paul --ssh --vm-size small

Azure CLI VM created

Unlike the Powershell cmdlets which honour my default storage account, it seems as if the Windows version of the command line tools has decided to use the first storage account (paulbouwerbacpac) it found in my subscription and not the storage account I specified ! Hope this gets fixed sometime.

You can see the image copied from VM Depot under the Images tab of the Virtual Machines section in the portal. As can be seen from the command line output above, this image is deleted once the virtual machine creation is complete.

Portal - verify image created in storage account

If you have a look at the Disks tab of the Virtual Machines section in the portal, you’ll see the OS Disk (vhd) once your virtual machine has been created.

Portal - verify vhd created in storage account

And finally, the virtual machine is running. This can be confirmed via the portal.

Portal - verify VM running

Create http endpoint

Typing the following at the command line shows that our ssh public endpoint has been created as per the –ssh switch when we created out virtual machine.

azure vm endpoint list pbsolr4

Solr is web based so we’ll need to add an http public endpoint too. Typing the following at the command line will result in a public endpoint being created on port 80 which will be routed internally to port 80 and will have a name of http.

azure endpoint create pbsolr4 80 80 --endpoint-name "http"

Azure CLI create http endpoint

The creation of this new endpoint can be confirmed in the portal by browsing to the Endpoints tab of our virtual machine.

Portal - verify endpoints

It’s running !

Browsing to pbsolr4.cloudapp.net/solr returns the Solr dashboard. Solr is up and running and our public endpoint on port 80 (http) is working.

Solr 4 running

I can also SSH to pbsolr4.cloudapp.net on port 22 (ssh).

SSH into pbsolr4

That was too easy ! There are loads of images currently available and I expect lots more to follow. VM Depot and their partners are making it really easy to get up and running quickly with these pre-configured environments. I’m impressed !
