I thought to write this post which might help my fellow developers to know how to create a CI build for any web application or web API through Team Services of VSO. Just like in one of the post I have explained how we can create a NuGet package using CI build, this post might give more insight about building and deploying an web application directly to Azure using CI build. Let’s get through the steps involved.
Step 1: Install and configure Azure PowerShell
This step is highly important if you don’t have Azure PowerShell installed. The cmdlets of Azure PowerShell can be used to create/configure cloud apps/services, VM, virtual networks, etc. Download an install Azure PowerShell from this link.
Once installed open Windows PowerShell in administrative mode and run the following Azure PowerShell cmdlets to get details of your Azure subscription and resources available. Main that you need is your Subscription Name and Subscription Id.
Command to get Azure Account Information: Login-AzureRmAccount
Command to get Azure Resources available: Get-AzureRmResource
Command to get the Subscription Name and Id: Get-AzureRmSubscription
Command to get the Azure Publish Settings File: Get-AzurePublishSettingsFile
This command is important to get profile settings for publishing your web app in Azure. This will download the publish settings file along with the credentials in your local box.
Step 2: Create New Service Endpoint in Team Services dashboard
This step will help us to register or add our Azure subscription to TFS. This is done only once and at collection level using the Service tab. Just select New Service Endpoint and select Azure Classic.
In Add New Azure Classic Connection choose Subscription Id and Subscription Name that you got from Azure Command Get-AzureRmSubscription. The Connection Name can be based on your preferred one. You can even open the downloaded Publish Settings file to get the Subscription Id and Subscription Name. Also from the file, copy the content of Management Certificate and paste it in place holder as shown below while creating the new Connection.
Now this service endpoint is ready to be used while publishing the azure web app.
Step 3: Configure the Build and Deployment properties of Team Project
Create the build definition file for the team project for which you want to instantiate the CI build at every check in process to source control. For that select Azure WebApp from the Deployment tab of Build Definition window.
As usual in Build definition created, update your Mapping information to point to source control repository of your solution in Repository Tab. Update your CI filter in Trigger tab to point to source control repository of your solution.
Next lets select the Build tab and select Azure Deployment. In details section, you need to select the new service endpoint created and select the Web App Name.
That’s all we need. Now you can queue the build to see how it works.
