Deployment methods (Git, ZIP, CI/CD) in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to deploy an app using Git in Azure CLI.

Azure

az webapp deployment source config --name myApp --resource-group myResourceGroup --[1]

Drag options to blanks, or click blank then click option'

Abranch

💡 Hint

Common Mistakes

Using 'branch' instead of 'repo-url' will cause the command to fail.

Confusing 'slot' with repository information.

The repo-url option specifies the Git repository URL for deployment.

Complete the command to deploy a ZIP package to Azure App Service.

Azure

az webapp deployment source config-zip --resource-group myResourceGroup --name myApp --src [1]

Drag options to blanks, or click blank then click option'

Aapp.json

Bapp.zip

Capp.js

Dapp.tar

💡 Hint

Common Mistakes

Using a non-ZIP file like .js or .json will cause deployment errors.

The --src option expects a ZIP file for deployment.

3fill in blank

Fix the error in the Azure DevOps pipeline YAML to trigger on push to main branch.

Azure

trigger:
  branches:
    include:
      - [1]

Drag options to blanks, or click blank then click option'

Amain

Bdevelop

Cfeature

Drelease

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'develop' or other branch names will not trigger the pipeline on main branch pushes.

The pipeline should trigger on pushes to the main branch.

4fill in blank

hard

Fill both blanks to define a CI/CD pipeline step that builds and deploys an app.

Azure

- stage: BuildAndDeploy
  jobs:
  - job: Build
    steps:
    - script: dotnet build [1]
    - script: az webapp deploy --name myApp [2]

Drag options to blanks, or click blank then click option'

A--configuration Release

B--resource-group myResourceGroup

C--slot production

D--verbose

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--slot production' without specifying resource group causes errors.

Omitting build configuration leads to default debug build.

The build step uses --configuration Release to build the app for release.

The deploy step requires the resource group with --resource-group.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that filters and transforms deployment logs.

Azure

filtered_logs = [1]: log.upper() for log in logs if [2].startswith('[3]')

Drag options to blanks, or click blank then click option'

A{log.lower()

Blog

Cerror

D{log

Attempts:

3 left

💡 Hint

Common Mistakes

Using parentheses instead of curly braces causes syntax errors.

Using 'log.lower()' as key instead of 'log' changes the keys unexpectedly.

The dictionary comprehension starts with {log as the key.

We filter logs where log starts with 'error'.

Practice

1. Which deployment method in Azure allows you to push your app code directly from your source code repository?

easy

A. Manual file upload

B. ZIP deployment

C. FTP deployment

D. Git deployment

Solution

1. Step 1: Understand Git deployment

   Git deployment connects your Azure app directly to your Git repository, pushing code changes automatically.

2. Step 2: Compare with other methods

   ZIP deployment uploads a packaged file, manual upload and FTP are manual and not direct from repo.

3. Final Answer:

   Git deployment -> Option D

4. Quick Check:

   Direct repo push = Git deployment [OK]

Hint: Git deployment means pushing code from your repo directly [OK]

Common Mistakes:

• Confusing ZIP deployment with Git deployment
• Thinking FTP is automated from repo
• Assuming manual upload is Git-based

2. Which of the following is the correct Azure CLI command to deploy a ZIP package to an Azure Web App named myapp in resource group mygroup?

easy

A. az webapp deploy zip --resource-group mygroup --app-name myapp --file app.zip

B. az webapp deployment source config-zip --resource-group mygroup --name myapp --src app.zip

C. az deployment zip --resource-group mygroup --webapp myapp --package app.zip

D. az webapp deployment upload-zip --resource-group mygroup --name myapp --zip-file app.zip

Solution

1. Step 1: Identify correct Azure CLI syntax for ZIP deployment

   The official command is az webapp deployment source config-zip with parameters for resource group, app name, and source ZIP file.

2. Step 2: Check options for syntax correctness

   az webapp deployment source config-zip --resource-group mygroup --name myapp --src app.zip matches the correct command and parameters exactly; others use incorrect commands or flags.

3. Final Answer:

   az webapp deployment source config-zip --resource-group mygroup --name myapp --src app.zip -> Option B

4. Quick Check:

   Correct CLI command for ZIP deploy = az webapp deployment source config-zip --resource-group mygroup --name myapp --src app.zip [OK]

Hint: Remember 'config-zip' is the key command for ZIP deploy [OK]

Common Mistakes:

• Using wrong command verbs like 'deploy' or 'upload-zip'
• Mixing parameter names like --app-name vs --name
• Forgetting to specify the source ZIP file with --src

3. Given this Azure DevOps pipeline snippet for CI/CD deployment:

trigger:
  branches:
    include:
      - main

steps:
- task: AzureWebApp@1
  inputs:
    azureSubscription: 'MyAzureSub'
    appName: 'myapp'
    package: '$(System.DefaultWorkingDirectory)/drop/app.zip'

What happens when you push code to the main branch?

medium

A. The pipeline triggers and deletes the Azure Web App

B. The pipeline triggers but does not deploy anything

C. The pipeline triggers and deploys the ZIP package to the Azure Web App

D. The pipeline does not trigger on main branch pushes

Solution

1. Step 1: Analyze the trigger section

   The pipeline triggers on pushes to the main branch as specified in the trigger include list.

2. Step 2: Understand the deployment task

   The AzureWebApp@1 task deploys the ZIP package located at the specified path to the Azure Web App named 'myapp'.

3. Final Answer:

   The pipeline triggers and deploys the ZIP package to the Azure Web App -> Option C

4. Quick Check:

   Push to main triggers deploy task = The pipeline triggers and deploys the ZIP package to the Azure Web App [OK]

Hint: Trigger on main means pipeline runs and deploys ZIP package [OK]

Common Mistakes:

• Assuming pipeline triggers on other branches
• Thinking deployment task does nothing
• Confusing deployment with deletion

4. You configured a CI/CD pipeline to deploy your app, but the deployment fails with an authentication error. What is the most likely cause?

medium

A. Incorrect Azure subscription service connection in the pipeline

B. ZIP package file is missing from the build artifacts

C. App name in the pipeline does not match the Azure Web App

D. Pipeline trigger is set to the wrong branch

Solution

1. Step 1: Identify cause of authentication error

   Authentication errors usually mean the pipeline cannot access Azure resources due to wrong or missing service connection credentials.

2. Step 2: Evaluate other options

   Missing ZIP or wrong app name cause deployment errors but not authentication errors; wrong trigger prevents pipeline start.

3. Final Answer:

   Incorrect Azure subscription service connection in the pipeline -> Option A

4. Quick Check:

   Auth error = service connection issue [OK]

Hint: Auth errors usually mean bad Azure service connection [OK]

Common Mistakes:

• Blaming missing ZIP for authentication errors
• Confusing app name mismatch with auth failure
• Assuming trigger issues cause auth errors

5. You want to automate deployment so that when code is pushed to GitHub, it builds, tests, and deploys your app to Azure automatically. Which combination of deployment methods should you use?

hard

A. CI/CD pipeline connected to GitHub with automated build and deploy steps

B. Manual ZIP deployment after pushing code to GitHub

C. FTP deployment triggered by GitHub webhook

D. Git deployment directly from GitHub without build or test

Solution

1. Step 1: Understand automation needs

   Automating build, test, and deploy requires a CI/CD pipeline connected to the source repository.

2. Step 2: Compare deployment methods

   Manual ZIP and FTP are manual or partial automation; Git deployment pushes code but lacks build/test automation.

3. Final Answer:

   CI/CD pipeline connected to GitHub with automated build and deploy steps -> Option A

4. Quick Check:

   Full automation = CI/CD pipeline [OK]

Hint: Full automation needs CI/CD pipeline linked to GitHub [OK]

Common Mistakes:

• Thinking Git deployment automates build and test
• Assuming FTP can automate deployment fully
• Using manual ZIP deploy for automation
