You can set up a CI/CD pipeline to deploy your apps on a Kubernetes cluster with Azure DevOps by leveraging a Linux agent, Docker, and Helm.
Step 1: Create a service principle in Azure Active Directory (Azure AD) We need to assign 3 specific service principals with specific Azure Roles that need to interact with our ACR and our AKS.
Create a specific Service Principal for our Azure DevOps pipelines to be able to push and pull images and charts of our ACR.
Create a specific Service Principal for our Azure DevOps pipelines to be able to deploy our application in our AKS.
Step 2: Add a Helm package and deploy a task to the deployment pipeline This is the DevOps workflow with containers:
Step 3: Add a Docker Compose task to the deployment pipeline.
Dockerfile file is a script leveraged by Docker, composed of various commands (instructions) and arguments listed successively to automatically perform actions on a base image in order to create a new Docker image by packaging the app.

To complete this task, sign in to the Microsoft Azure portal.
You need to back up an Azure web app named az400-11566895-main every five hours to an Azure Storage accountin your resource group.
To complete this task, sign in to the Microsoft Azure portal.
Correct Answer:
See solution below.
Explanation:
With the storage account ready, you can configure backs up in the web app or App Service.
Open the App Serviceaz400-11566895-main, which you want to protect, in the Azure Portal and browse to Settings > Backups. Click Configure and a Backup Configuration blade should appear.
Select the storage account.
Click + to create a private container. You could name this container after the web app or App Service.
Select the container.
If you want to schedule backups, then set Scheduled Backup to On and configure a schedule: every five hours Select your retention. Note that 0 means never delete backups.
Decide if at least onebackup should always be retained.
Choose if any connected databases should be included in the web app backup.
Click Save to finalize the backup configuration.
