Deployment methods (Git, ZIP, CI/CD) in Azure - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Git deployment in Azure?

Git deployment in Azure means you connect your Azure app to a Git repository. When you push code to the repo, Azure automatically updates your app with the new code.

beginner

How does ZIP deployment work in Azure?

ZIP deployment lets you package your app files into a ZIP file and upload it to Azure. Azure then extracts and runs your app from those files.

beginner

What is CI/CD in the context of Azure deployments?

CI/CD stands for Continuous Integration and Continuous Deployment. It means automatically testing and deploying your app whenever you change the code, using tools like Azure DevOps or GitHub Actions.

Why use CI/CD instead of manual deployment?

CI/CD saves time and reduces mistakes by automating tests and deployments. It helps deliver updates faster and more reliably.

intermediate

Name one advantage of using Git deployment over ZIP deployment.

Git deployment automatically updates your app when you push code, making it easier to track changes and collaborate with others.

Which deployment method automatically updates your Azure app when you push code to a repository?

A Git deployment

B ZIP deployment

C Manual FTP upload

D Local file copy

Git deployment connects your Azure app to a Git repo and updates the app automatically on code push.

What file format is used in ZIP deployment to upload your app to Azure?

A .tar

B .iso

C .exe

D .zip

ZIP deployment uses a .zip file containing your app files to upload and deploy.

What does CI/CD stand for in Azure deployment?

A Cloud Infrastructure / Cloud Development

B Code Integration / Code Delivery

C Continuous Integration / Continuous Deployment

D Container Integration / Container Deployment

CI/CD means Continuous Integration and Continuous Deployment, automating testing and deployment.

Which tool can be used to implement CI/CD pipelines for Azure apps?

A Microsoft Word

B Azure DevOps

C Windows Explorer

D Azure Storage Explorer

Azure DevOps is a tool that helps create CI/CD pipelines for automated deployments.

What is a key benefit of using CI/CD pipelines?

A Faster and reliable deployments

B Slower release cycles

C Manual code review

D More manual work

CI/CD pipelines automate testing and deployment, making releases faster and more reliable.

Explain the differences between Git deployment, ZIP deployment, and CI/CD in Azure.

Think about how each method updates the app and how much automation is involved.

Describe why CI/CD is important for modern app deployment in Azure.

Consider the benefits of automation and speed in software delivery.

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
