Containerization & Deployment

Containerize and deploy .NET Core microservices — Docker best practices, Kubernetes deployment, Helm charts, and service mesh integration.

Production Deployment Patterns

Docker Multi-Stage: Build → Test → Publish → Runtime stages. Use .dockerignore to exclude bin/, obj/, .git/. Pin base image versions for reproducibility
Docker Compose for Dev: Define all microservices, databases, message brokers — docker-compose up starts the entire ecosystem. Override files for environment-specific config
Kubernetes Manifests: Deployment (replicas, rolling updates), Service (load balancing, DNS), Ingress (external access), ConfigMap/Secret (configuration)
Helm Charts: Package Kubernetes manifests with templating — one chart per microservice, values files per environment (dev, staging, production)
Service Mesh (Istio): Transparent sidecar proxies — mTLS between services, traffic routing (canary/blue-green), circuit breaking, distributed tracing. No code changes
GitOps (ArgoCD): Declarative deployment — Git is the source of truth. Push manifest changes → ArgoCD applies to cluster automatically
