Containerizing & Deploying Next.js Applications with Docker and Kubernetes

Deploying Next.js in containerized environments requires minimizing image footprint and securing container runtime permissions.

1. Next.js Standalone Output Mode

Configuring output: 'standalone' in next.config.ts automatically traces dependency trees, reducing final Docker image size from 1.2GB to under 120MB.

2. Multi-Stage Dockerfile Blueprint

Multi-stage builds separate node_modules caching, compilation stages, and minimal Alpine production runners under non-root nodejs users.

3. Kubernetes Deployment & Health Probes

Configure livenessProbe and readinessProbe endpoints along with Horizontal Pod Autoscalers (HPA) for seamless zero-downtime rolling updates.
