Setup CD using Release Pipeline for Azure Function (Part 5- Azure Function CI/CD)

Pre-requisites

Login to Azure Devops and open Project created in previous post.

1.      Create Pipeline

i) Click on “Releases” in the left navigation menu under “Pipelines” followed by “New Pipeline” button.

ii) We will see the following options on the release pipeline window. Select “Add an artifact”

iii) Select the source build pipeline and click “Add”

      

iv) Configure variables

v) Enable Continuous Deployment Trigger

vi) Add 2 Stages, Develop and Test and configure tasks. To add stages use “Add” button.

vii) Once the stages added, we need to configure tasks for both the stages. Search for template “Azure Functions for .Net” and click “Apply”.

Configure the task with FunctionApp name defined in the variables in step (iv).

Once the configuration completed for both the stages, release pipeline will be ready to use.

viii) To test release pipeline, let’s manually create a release for the previous build [Refer], to do this we need to click on “Create Release” button.

ix) Select the develop stage for manual trigger along with the source build artifacts and click “Create”

Note – This manual step is just for testing, in actuals, once you push code from visual studio your build pipeline will trigger followed by release pipeline thus creating a release automatically. There will be no manual release trigger.

x) Navigate to Releases to see recent release created.

Open the recent release to see the details of the stages. We see the develop stage triggered automatically and succeeded, this will deploy the FunctionApp to Dev resource group in azure.

In addition, we can see “Test” stage is queued, waiting for agent.

Once the agent is available, test stage is triggered, which will deploy the FunctionApp to QA resource group in azure.

Finally, we see, both the stages completed successfully, thus deploying the FunctionApp to both the resource groups “Dev” and “QA” from a single release trigger.

Hope this gives you clear picture of continuous deployment. This completes series Deploy Azure Function via Azure Devops CI/CD Pipelines.
