Volumes and Config

Foundations & App Service → Containers & AKS → DevOps & Security → Projects

Foundations & App Service · 1 — Host · ~6 min · Docker on Azure

What is this?

Volumes and Config is containerization for Azure: images, Dockerfiles, and local verification before cloud.

Why should you care?

Same image should run locally and in ACR/AKS.

See it live — copy this example

Use an Azure lab/free subscription. Prefer Azure CLI or Portal. Delete idle App Service plans, SQL DBs, and AKS clusters when practice is done.

# Volumes and Config
docker build -t cloudverse-api:local .
docker images
# later: tag + push to ACR

What happened?

Build and list images locally.
Push comes after the image runs.

Practice next

Run the CLI/portal steps in a lab subscription.
Write the resource names you used.
Note estimated monthly cost for the SKU.
Repeat in a second region (conceptually).
Add the resource to a simple architecture diagram.

Remember

You can explain Volumes and Config simply. You practiced one Azure action. You know a cost or security risk.

Volumes and Config in CloudVerse

Your team applies volumes and config while building on Azure.

Outcome: A concrete portal/CLI next step exists.

Example scenario: Your team publishes a shared MyCompany.Logging NuGet package to Azure Artifacts. Another team adds the feed to their project’s NuGet.config and installs the package like any normal NuGet dependency. 3⃣ How do you version your NuGet packages in a CI/CD pipeline?

Versioning is usually handled automatically in the build pipeline — so every build produces a unique version number. You can version packages using: Build ID, Git commit hash, or semantic versioning (e.g., 1.2.3). Exampl…

Reference the artifact (.zip) from your build pipeline. Example scenario: A .NET Core app gets built, zipped, and deployed automatically to the Staging slot of an Azure Web App after successful testing. 5⃣ How do you manage configuration transformations (e.g., web.config or appsettings.json)? Follow:

You can use XML or JSON transformation tasks in your release pipeline to adjust settings per environment. Example (Classic): Add a File Transform or Replace Tokens task. Replace values like database connection strings or…

Modify the YAML as needed. Example (YAML): trigger: - main pool: vmImage: 'windows-latest' steps: - task: UseDotNet@2 inputs: packageType: 'sdk' version: '8.0.x' - script: dotnet restore - script: dotnet build --configuration Release - script: dotnet test --no-build --verbosity normal This pipeline restores packages, builds, and runs tests for your .NET app. 5⃣ What tasks are commonly used in .NET build pipelines?

Common tasks: UseDotNet@2 → Installs .NET SDK. NuGetCommand@2 → Restores NuGet packages. DotNetCoreCLI@2 → Builds, tests, and publishes your app. PublishBuildArtifacts@1 → Stores your compiled output. Example: .NET Core…
