I'm about to start a new project and want to have it with a continuous integration (CI) and continuous deployment (CD). I've been using VSTS for a while now but didn't have the chance to try the new pipelines. If you didn't know VSTS as been rebranded/ redefined as Azure Devops. Before going in with the real thing I decided to give it a try with a simple project. This post is to relay those first steps.
Get Started
Let's start by creating our Azure Devops project. Navigate to Dev.Azure.com and if you don't already have an account create one it's free! Once you are logged-in, create a new project by clicking the New project blue button in the top right corner.
You will need to provide a unique name and a few simple information.
The Application
First thing first, we need an application. For this post, I will be using a simple Asp.Net Core site. For the repository, we have options. AzureDevOps (ADOps) support many repository: GitHub, Bitbucket, private Git and its own. Because the project I've created is public I decided to keep the code at the same place as everything else.
From the left menu, select Repos. From here if the code already exist just add a remote repository, or clone the empty one on your local machine, the usual. Create and add your code to that repository.
The Azure WebApp
The next step is to create a placeholder for our CD pipeline. We will create an empty shell of a web application in Azure with these three Azure CLI commands. You can execute them locally or from the Cloud Shell. (Don't forget to validate that you are in the good subscription)
az group create --name simplegroup --location eastus
az appservice plan create --name simpleplan --resource-group simplegroup --sku FREE
az webapp create --name simplefrankweb --resource-group simplegroup --plan simpleplan
The first command will create a Resource group. Then inside of this group we create a service plan, and finally we create a webapp to the mix.
Continuous Integration
The goal is to have the code to get to compile at every commit. From the left menubar, select Pipelines, and click the create new button. The first step is to identify where our code is, as you can see Azure DevOps is flexible and accept code from outside.
Select the exact repository.
This third step displays the YAML code that defines your pipeline. At this point, the file is not complete, but it's enough to build, we will come back to it later. Click the Add button to add the azure-pipelines.yml file at the root level of your repository.
The build pipeline is ready click the Run button to execute it for the first time. Now at every commit, the build will be triggered. To see the status of your build just on to into the build section from the left menubar.
Continuous Deployment
Great, our code gets to compile at every commit. It would be nice if the code could also be automatically deployed into our dev environment. To achieve that we need to create a Release Pipeline. And our pipeline will need artifacts. We will edit the azure-pipelines.yml to add two new tasks. You can do this directly in the online repository or just from your local machine; remember the file is at the root. Add these commands:
Those two tasks are to publish our application (package it), and make it available in our Artifact folder. To learn more about the type of command available and see example have a look the excellent documentation at: https://docs.microsoft.com/azure/devops/pipelines/languages/dotnet-core. Once you are done, save and commit (and push if it was local).
From the left menubar, click on e the Pipeles, select Release, and clienk the New Release blue button. Select the template that matches your application. For this post Azure App Service deployment is the one we need.
The next thing to will be to rename the environment for something else than Stage 1, I named mine "to Azure" but it could be dev, prod or anything that make sense for you. Click on the Add an Artifact button.
You will now specify to the pipeline were to pick the artifacts it will deploy. In this case, we want the "output" of our latest build. And I renamed the Source alias as Drop.
To get our continuous deployment (CD) we need to enable that trigger by clicking on the little lightning bolt and enabled it.
The last step to configure the Release pipeline is to specify a destination. By clicking on the "1 job, 1 task" in the middle of the screen (with the little red exclamation point in a circle), that will open the window where we will do that.
Select the subscription you would like to use, and then click on the Authaurize button on the right. Once it's done go change the App Service Name. Click on it and wait 2-3 seconds you should see the app we created with our Azure CLI display. Select it, and voila!
Now add a ReadMe.md file by checking out the code on your local machine or directly in Azure DevOps. Grab a badge from the build and/or release and copy paste it in the ReadMe. To get the code snippet of your badge, go to your build/ release definition, and click the ellipse button. Select Status badge and copy the snippet that matches your destination file (in our case the Markdown).
Now when you go to the Overview page, you will have a nice badge that informed you. It also works on any web page just use the HTML snippet instead.

Windows Virtual Desktop (null) - This week Microsoft announced what looks like a very simple way to get powerful environments without all the trouble to maintain them. More to come.
Most of the time when we use an Azure Devtest Lab it to Test our own application. This means that will need to install them on the virtual machines, every time. To do that, we need to create a custom artifact and add it to our formulas or to our claimable VMs. Lucky for us, creating a custom artifact is much easier than you may think. In fact, this post I will show you how easy it can be.
Goal
I want to create an artifact available from a private repository (Git from dev.azure.com in this case) that will set the timezone inside the VM.
Getting started
First, let's use a section in the Azure portal that is very useful; the Get Started section. In the portal navigate to your DevTest Lab (1), and select the Getting Started option from the left menu bar (2). In this new bar scroll down to the Lear more area and select Sample artifacts and scripts (3).
That will open the DevTestLab artifacts, scripts and samples project from Azure on Github. Open the folder Artifact, to see the list of all the usual artifacts you find in the public repo that is available by default in the portal.
Notice how all artifacts are in their own folder. When you create a new artifact, you can always come here and pick something similar to what you are trying to do. This way, you won't start from scratch. Let's open windows-vsts-download-and-run-script. An artifact is defined in the file Artifactfile.json. This file is mandatory and cannot be renamed. You can put scripts, images, or anything else you need inside this folder.
Open the Artifactfile.json file and have a look.
As you can see it's a simple JSON file. In the section (A) you will define the title, description, publisher, OS and the Icon. Note that the Icon must be accessible publicly, it could be on github, a blob storage or on a website. Section (B) is to define all the parameters you may need to install your artifact on the VM. Finally In (C) it's the command to execute.
Create the Artifact
Here is the JSON for our windows-Set-TimeZone artifact. A made it very static by not passing any parameter, but in a reel situation, a timezone parameter would be better.
Artifactfile.json
{
"$schema": "https://raw.githubusercontent.com/Azure/azure-devtestlab/master/schemas/2016-11-28/dtlArtifacts.json",
"title": "Set TimeZone to Eastern Standard Time",
"description": "Execute tzutil command on the VM set set the Time Zone",
"publisher": "FBoucher",
"tags": [
"PowerShell"
],
"iconUri": "https://raw.githubusercontent.com/Azure/azure-devtestlab/master/Artifacts/windows-run-powershell/powershell.png",
"targetOsType": "Windows",
"parameters": { },
"runCommand": {
"commandToExecute": "tzutil.exe /s \"Eastern Standard Time\""
}
}
Create an artifact repository
For this post, I'm using Git from Azure Devops (dev.azure.com) previously named VSTS, but any private repository should works. If it's not already done create a project and go to the Repos section. Create a root folder named Artifacts or something else if you prefer. Then add a new folder for your artifact. To follow the best practices you should start with the name of your artifact by the name of the targeted OS; in my case windows-Set-TimeZone. Now add the file Artifactfile.json defined previously.
Note the url of the repository, it should be easy to get it by click on the Clone button that is on the top right of the screen.
Add repository to DevTest Lab
Now we need to add this repository to our Devtest Labs. From the portal.azure.com, open the blade of your lab. From the left panel, click on Repository, then click the Add button.
It's time to use the information noted previously. This is about the Repository, not the artifact.
Use the Artifact
The only thing left is to use our artifact. You can find it while creating a VM or a formula. When you have parameters define in your Artifactfile.json, the parameters will be listed in a form completly a the left.
And if you try it, you will see that the time match the desired timezone. Here my PC is set to display with a format of 24H put it's the same... yep I'm in Eastern Standard Time.
Add it to an ARM template
Doing it with the nice interface is good when you are learning. However, we all know that no DevOps will do that manually every time. So let's add our Repository to our ARM template. If you need more detail on the deployment method, I explain it in a previous post How to be efficient with our Azure Devtest Lab deployments.
When you don't know the type or the structure of a resource, you can always go in the Resource Explorer (resources.azure.com) there will be able to find your resource and see how it's defined.
So for this post our artifactsources will look like this:
An artifactsources goes in the Resources list inside the Devtest Labs.
In an ARM template you have the main node Resources (A), then you will have the Lab node (B). Inside this node, you should see second resources list (C), where the Virtual Network is defined. The artifactsources should go there.
Then when you declare your formula, you just need to reference this repository, exactly like the public one.
The Devtest labs is a fantastic tool to quickly build environments for development & test purposes and for a classroom. It offers great tools to restrict the users without removing all their freedom. It will speed up the boarding, with its claimable VMs that are already created and are waiting for the user. Formulas will help ensure you that you always get the latest version of your artifact installed on those VMs. And finally, the auto-shutdown will keep your money where it should stay...in your pocket.
In this post, I will show you how to deploy an Azure Devtest Lab with an Azure Resource Manager (ARM) template, and create the claimable VMs based on your formulas in one shot.
Step 1 - The ARM template
First, we need an ARM template. You can start from scratch of course, but it may be a lot of work if you are just getting started. You can also pick one from GiHub and customize it.
What I recommended, is to create a simple Azure Devtest Lab directly from the Azure portal. Once your lab is created, go in the Automation script option of the resourcegroup and copy/paste the ARM template in your favorite text editor.
Now you must clean it. If you don't already know it, use the 5 Simple Steps to Get a Clean ARM Template method, it an excellent way to get started.
Once the template is clean we need to add a few things that didn't follow during the export. Usually, in an ARM template, you get one list named resources. However, a Devtest Lab also contains a list named resources but it's probably missing.
See In the following example, I added the labs resources list just after the lab's location. This list must contain a virtualnetworks. It's also a good idea to add a schedules and a notificationChannels. Those two will be used to shut down automatically all the VMs and to send a notification to the user just before.
Now that the Devtest lab is well defined, it's time to add our formulas. If you had created some already from the portal, don't look for them in the template. At the moment, export won't script the formulas.
A quick way to get the JSON of your formulas is to create them from the portal and then use Azure Resources Explorer to get the code.
In a web browser, navigate to https://resources.azure.com, to open your Resource Explorer. Select the subscription, resource group, and lab that you are working on. In the node Formulas (4) you should see your formulas, click one and let's bring that JSON into our ARM template. Copy-paste it at the Resource level (the prime one, not the one inside the Lab).
Step 2.5 - The Azure KeyVault
You shouldn't put any password inside your ARM template, however, having them pre-define inside the formulas is pretty convenient. One solution is to use an Azure KeyVault.
Let's assume the KeyVault already exists, I will explain how to create it later. In your parameter file, add a parameter named adminPassword and let's reference the KeyVault. We also need to specify the secret we want to use. In this case, we will put the password in a secret named vmPassword.
Now to get the password in the ARM template just use a regular parameter, and voila!
Step 3 - The ARM Claimable VMs
Now we have a Lab and the formulas, the only thing missing is the claimable VM based on the formulas. It's impossible to create in one ARM template both formulas and VMs. The alternative is to use a script that will create our VMs just after the deployment.
az group deployment create --name test-1 --resource-group cloud5mins --template-file DevTest.json --parameters DevTest.parameters.json --verbose
az lab vm create --lab-name C5M-DevTestLab -g cloud5mins --name FrankDevBox --formula SimpleDevBox
As you can see in the second Azure CLI command, we are creating a virtual machine named FrankDevBox based on the formula SimpleDevBox. Note that we don't need to specify any credential because everything was pre-defined in the formula. Pretty neat!
Here a part of a script that will create if it doesn't exist a KeyVault and populate it. Then it will deploy our ARM template and finally, create our claimable VM. You can find all the code on my GitHub project: Azure-Devtest-Lab-efficient-deployment-sample.
[...]
# Checking for a KeyVault
searchKeyVault=$(az keyvault list -g $resourceGroupName --query "[?name=='$keyvaultName'].name" -o tsv )
lenResult=${#searchKeyVault}
if [ ! $lenResult -gt 0 ] ;then
echo "---> Creating keyvault: " $keyvaultName
az keyvault create --name $keyvaultName --resource-group $resourceGroupName --location $resourceGroupLocation --enabled-for-template-deployment true
else
echo "---> The Keyvaul $keyvaultName already exists"
fi
echo "---> Populating KeyVault..."
az keyvault secret set --vault-name $keyvaultName --name 'vmPassword' --value 'cr@zySheep42!'
# Deploy the DevTest Lab
echo "---> Deploying..."
az group deployment create --name $deploymentName --resource-group $resourceGroupName --template-file $templateFilePath --parameters $parameterFilePath --verbose
# Create the VMs using the formula created in the deployment
labName=$(az resource list -g cloud5mins --resource-type "Microsoft.DevTestLab/labs" --query [*].[name] --output tsv)
formulaName=$(az lab formula list -g $resourceGroupName --lab-name $labName --query [*].[name] --output tsv)
echo "---> Creating VM(s)..."
az lab vm create --lab-name $labName -g $resourceGroupName --name FrankSDevBox --formula $formulaName
echo "---> done <--- code="">

Conclusion
Would it be for developing, testing, or training, as soon as you are creating environments in Azure, the DevTest Labs are definitely a must. It's a very powerful tool that not enough people know. Give it a try and let me know what do you do with the Azure DevTest Lab?
