Azure DevOps - CI CD - Build And Release Pipeline - Azure Function

In this article, I am going to show how we can make a CI & CD Build and Release Pipeline for an Azure Function. Below is my process.

An existing Azure Functions App.

Create an Azure Function App through Code

Open Visual Studio 2017 and go to New -> Project.

Select Cloud => Azure Functions.

Click OK.

Select the HTTP Trigger Function. Click OK.

Leave everything as default. I just renamed the Function Name to (SayHelloFunction).

In addition, if we pass the Name as a query string, then the “Hello From Noida – Welcome – {Name}” Message will return.

Check-in Your Code to Azure Repos

Now, our Visual Studio Code is ready.

The next step is to create a project in Azure. Open here.

Log in with your credentials.

Create an organization here if you do not have.

I have rahsaxen1 (Organization)

Click on + New Project.

Click on "Create".

Now, we will commit our code into Azure Repos Git.

So, click on Repos from the left side menu.

Copy the Azure Repo Git URL.

https://dev.azure.com/rahsaxen1/_git/RAHULTestFunctionAppCICD

Now, open your Functions App code location.

We will commit our code into Azure Repo Git through Git Command.

Type cmd.exe and hit Enter - the command window will open.

Execute the below Git commands.

> git init
> git add .
> git commit -am "Add your app"
> git remote add origin <git Repo Url>
> git push -u origin –all

Now, check your Azure DevOps Project (Repos).

Build Pipeline For Azure Function

Now, click on Pipeline from the left-side menu.

Pipeline -> Build -> New Pipeline

Click on "Continue". Now, select a Template.

Select ASP.NET Core here and "Apply". Some default jobs will add.

Keep everything as default. Select Publish,

In Publish Job -> DeSelect Publish Web Projects because if this option is enabled, the Publish task will look for a web project in the repository and run the publish command.

Now, select the Triggers option.

Enable "Continuous Integration".

Save it.

Queue your build.

Click on "Run".

Build Pipeline has been successfully completed. Now, it is time to create a Release Pipeline.

Select Pipeline -> Release.

Select the Azure App Service Deployment template and "Apply".

Here, select Azure Subscription, App Type, and App Service Name.

Save it and now click on “Add an Artifact”.

Click Add. In addition, save it.

Make sure that the Continuous Deployment is enabled.

Now, check in the Azure Portal.

Navigate to Functions App.

The function is deployed successfully

Now, copy the function URL and browse it.

The function access level is Function. So, while browsing, we have to pass the function code as well.

Now, make any change in your Visual Code and commit your changes. Automatically, the Build will trigger and deployment will happen.

Commit your changes.

Now check you Build Pipeline.

Now check Release Pipeline,

Now check your function output by hitting function URL,
