Azure DevOps
Must read definition before interview
Azure DevOps is a complete DevOps platform by Microsoft that supports planning, development, CI/CD, testing, and monitoring.
Azure Pipeline
Git
Git cherry-pick is used to apply a specific commit from one branch to another branch without merging the entire branch. used when Hotfix needed in production.
GitOps is a deployment model where Git is the single source of truth for infrastructure and application deployments.
git fetch downloads changes from the remote repository but does NOT apply them to your local branch. git merge combines another branch into your current branch and creates a merge commit. git pull is a shortcut for git fetch + git merge.
Conflict A merge conflict happens when Git cannot automatically merge changes because someone has updated the same lines of a file were modified differently in two branches occurs when: Two people edit the same line in a file .One deletes a file while another modifies it Rebase or cherry-pick conflicts
check conflicted files git status Open the conflicted file
Resolve the conflict manually Decide what to keep- correct code
Accept current branch git checkout --ours app.js Accept incoming branch git checkout --theirs app.js
How to Avoid Merge Conflicts (Best Practices)
Pull latest changes frequently
Keep feature branches short-lived
Use git pull --rebase
Avoid committing large files
Communicate before big changes
SonarQube is a static code analysis tool used to detect code quality issues, bugs, vulnerabilities, and security hotspots.
SonarQube ensures code quality and security by enforcing quality gates during CI/CD

QA
Got it — I’ll frame this interview-ready, concise but strong (not textbook, but practical DevOps/SRE level answers). You can literally speak this.
I’ll structure it Q → Answer style 👇
✅ Interview-Ready Answers
🔹 How do you design CI/CD pipeline for multiple stages?
Answer:
I design pipelines using environment-based stages with clear separation of responsibilities. Typical flow:
1️⃣ Source Stage
Trigger on PR / merge
Branch policy validation
2️⃣ Build Stage
Compile/package
Unit tests
Static code scan
3️⃣ Artifact Stage
Version artifacts
Push to registry (Docker/Artifact feed)
4️⃣ Deploy Stages
Dev → QA → Staging → Production
Use approvals & gates between environments
Infra validation before deploy
5️⃣ Post Deploy
Smoke tests
Monitoring hooks
Rollback readiness
Key design principles
Reusable YAML templates
Parameterized stages
Environment approvals
Parallel jobs where possible
Secrets externalized
👉 I typically implement this in Azure DevOps/GitHub Actions/Jenkins using multi-stage YAML pipelines.
🔹 Which branching strategy are you using?
Answer:
Depends on team size, but commonly:
✔️ GitFlow (structured teams)
main → production
develop → integration
feature/*
release/*
hotfix/*
✔️ Trunk-based (my preference lately)
Short-lived feature branches
Frequent merges to main
Heavy automation + feature flags
Why I prefer trunk-based
Faster delivery
Less merge conflicts
Better CI/CD flow
🔹 What is GitOps?
Answer:
GitOps is an operational model where Git is the single source of truth for infrastructure and application deployment.
Instead of pushing deployments manually:

Controller (ArgoCD/Flux) watches repo
Automatically syncs cluster state
Benefits
Versioned infra
Easy rollback
Auditability
Declarative deployment
I’ve used this with Kubernetes using ArgoCD.
🔹 What is Blue-Green Deployment?
Answer:
Deployment strategy using two environments:
Blue → current production
Green → new version
Steps:
Deploy new version to Green
Test
Switch traffic
Keep Blue for rollback
Benefits
Zero downtime
Instant rollback
Commonly implemented via:
Load balancer switch
DNS routing
Kubernetes service switch
🔹 How do you integrate/handle secrets in pipelines?

Got it — I’ll answer these in clean interview-ready wording so you can speak them confidently. I’ll keep them practical and not overly theoretical.
✅ Interview-Ready Answers
🔹 How do you avoid secrets printing in logs?
Answer:
I follow a few best practices to ensure secrets never appear in logs:
Store secrets in secure stores (Azure Key Vault, pipeline secret variables)
Mark variables as secret/masked
Avoid echo/print commands in scripts
Disable verbose/debug logging when handling sensitive data
Use runtime injection instead of hardcoding
Limit log access via RBAC
Key line
Secrets are injected only at runtime and masked automatically by the pipeline engine.
🔹 How do you handle secrets in Kubernetes?
Answer:
Typical approach:
Use Kubernetes Secrets
Encrypt secrets at rest
RBAC restrictions
Mount as env variables or volumes
Production Best Practice
External secret manager integration
Azure Key Vault CSI Driver
Vault
Rotate secrets
Avoid storing plaintext in Git
Short summary
I prefer external secret management integrated with Kubernetes to improve security and rotation.
🔹 How do ArgoCD and Image Updater connect to AKS?
Answer:
ArgoCD runs inside the AKS cluster and connects using Kubernetes API.
Flow:
1️⃣ ArgoCD watches Git repo 2️⃣ Detects changes 3️⃣ Syncs manifests to AKS
Image Updater:
Monitors container registry (ACR)
Updates image tags in Git
ArgoCD detects commit
Deploys automatically
Result
Fully GitOps-based deployment cycle
🔹 What are Deployment Slots?
Answer:
