Task: Manage a Web App

Video: Azure App Service Management

Estimated time: 20 minutes

Goal

In this task you will manage a web app. You will change the tier of the web app and create a staging deployment slot. You will deploy code to the staging deployment slot and add a configuration setting for the production and staging slots. You will verify that both production and staging are working as expected.

Pre-requisites

Non-production Azure subscription
Azure Web app with code deployed
Archive file with web app deployment

See the Pre-requisite setup for instructions on provisioning the web app and downloading the archive file.

Requirements

Create a deployment slot
Deploy code to the deployment slot
Implement slot-based settings

Pre-requisite setup

You will need to download an archive file with web app code. You can download the archive from:

https://inedemoworkload.blob.core.windows.net/codedeploy/webapp.zip

This task also requires several Azure resources. To deploy the resources required for this task, run the following from a bash cloud shell:

curl https://inedemoassets.blob.core.windows.net/taskfiles/azure_admin/scripts/deploy-3671-T120-pre.sh | sh

This script provisions the following resources:

Resource	Name
Resource group	task-webapp-rg
Web app	**<a unique name>
App service plan	mgmt-asp

Support resources are not shown.

Requirement 1: Create a deployment slot

For the first requirement you must create a deployment slot named staging for the web app. Prior to creating the staging slot, you must change the performance tier of the mgmt-asp app service plan to S1 (standard, level 1).

Requirement 2: Deploy code to the deployment slot

For this requirement you will deploy the web app code to the staging slot. To complete this task:

Navigate to the staging slot in the web app blade.
Navigate to advanced tools
Under the tools menu, select Zip Push Deploy
Drag the webapp.zip file that you downloaded in the pre-requisite setup and drop it on the page
Wait for the installation to complete
Browse to the web app for the staging slot and confirm that it runs.

Requirement 3: Implement slot-based settings

Finally, you are going to add a configuration setting to the staging slot. Add an app setting named isTest with a value of true to the staging slot. Mark the setting as a slot setting. After the settings are saved, browse to the staging web app and verify that it now shows the following message near the top of the page:

This is a test site. Changes made to this site will not impact production data.

Clean up

Delete the task-webapp-rg resource group.
