CI-CD In Azure Web Apps Using Azure DevOps And Visual Studio

We will see how to perform Continuous Integration and Continuous Delivery (Known as CI/CD) in Azure Web Apps using Azure DevOps (Previously known as VSTS) and Visual Studio. I will create a simple Web App using visual studio and I will publish this Web App to Azure. I will enable Continuous Delivery in visual studio and then host the application in Azure DevOps using Git repository. I will make some code change in web application and commit the code to Git repository and will push the code to Azure DevOps. Continuous Integration will happen, and new build will be deployed to Azure automatically.

In this article we will see how to perform Continuous Integration and Continuous Delivery (Known as CI/CD) in Azure Web Apps using Azure DevOps (Previously known as VSTS) and Visual Studio. I will create a simple Web App using Visual Studio (I am using Visual Studio 2017 free community edition) and I will publish this Web App to Azure. I will enable Continuous Delivery in Visual Studio and then host the application in Azure DevOps using Git repository. I will make some code change in web application and commit the code to Git repository and will push the code to Azure DevOps. Continuous Integration will happen, and a new build will be deployed to Azure automatically.

It will reduce all our work load for build and deployment. We will see all the actions step by step.

Step 1 - Create a Web application in Visual Studio.

Please choose ASP.NET Web Application template.

It will take some time to create a new Azure Web App and Service Plan and it will automatically publish to Azure.

Our Web App is ready now. This is a simple app.

After some time, pipe lines will be finished.

Please open Azure DevOps to see our Project repository and Pipelines. (DevOps Link)

You can see that new project repository is created in Azure DevOps.

Step 4 - Continuous Integration and Continuous Delivery (CI/CD)
 
We can check the Continuous Integration and Continuous Delivery now. We can modify two files in our application. I have modified the Index.cshtml file. Also modified _Layout.cshmtl file.

In this application we saw how to create a Web Application in Visual Studio and we published the App to Azure and we created an Azure DevOps repository for our Web App and enabled the Continuous Delivery. We modified two Razor View files in our web application and commit and push the code changes to Azure DevOps. CI/CD feature automatically created a Batch build and deployed the application to Azure. Microsoft has really simplified the job for DevOps engineers.
