Why Kubernetes?
Kubernetes provides automated deployment, scaling, and management of containerized applications. It's the industry standard for production-grade deployments.
Prerequisites
You need a working Docker image, kubectl configured, and a Kubernetes cluster (EKS, GKE, or AKS).
Writing Your Deployment
Define your Deployment, Service, and Ingress resources in YAML. Always set resource limits and liveness/readiness probes.
Zero-Downtime Deployments
Use rolling updates with proper minReadySeconds and maxSurge settings to ensure zero downtime during deployments.
