Kubernetes Core Ideas

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

Containers & AKS · 2 — Orchestrate · ~6 min · Containers & Kubernetes Basics

What is this?

Kubernetes Core Ideas belongs to Kubernetes/AKS: running containers with declarative workloads.

Why should you care?

Multi-service CloudVerse systems need orchestration beyond one Web App.

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.

# Kubernetes Core Ideas
kubectl get deploy,svc,pods -A
# or: az aks show -g rg-cloudverse-dev -n aks-cloudverse-dev -o table

What happened?

kubectl shows workloads.
Prefer small lab clusters and delete when idle.

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 Kubernetes Core Ideas simply. You practiced one Azure action. You know a cost or security risk.

Kubernetes Core Ideas in CloudVerse

Your team applies kubernetes core ideas while building on Azure.

Outcome: A concrete portal/CLI next step exists.

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…

Track: Bugs and tasks are managed in Azure Boards. Follow: Example: A .NET Core API gets built automatically when code is pushed to main. If tests pass, it’s deployed to staging — and after approval, to production. 5⃣ What is a project in Azure DevOps and what resources can it include?

A project in Azure DevOps is like a container for everything related to a specific application or product. It can include: Code repositories Work items (stories, bugs) Pipelines (build/release) Test cases Artifacts Examp…

Testing and validating pipeline parity. Scenario: A company using Jenkins moves to Azure DevOps to unify code and pipelines. They convert Jenkinsfile logic to YAML, using tasks like DotNetCoreCLI@2 and AzureWebApp@1. Eventually, builds run in Azure-hosted agents with better visibility and governance. 11⃣ How would you implement zero-downtime deployment for an ASP.NET Core API?

Zero-downtime means your API stays live while deploying new versions. Ways to achieve it: Use Azure App Service Deployment Slots (swap after warm-up). Use Blue-Green or Rolling Deployment strategy. Run health checks befo…
