About This Architecture

Docker Compose to Kubernetes deployment mapping showing how a three-tier application (nginx reverse proxy, web service, API service, and PostgreSQL database) translates from docker-compose.yml to Kubernetes manifests. The diagram illustrates service discovery via ClusterIP Services, stateful database management using StatefulSet with PersistentVolumeClaim, and configuration management through ConfigMap and Secret resources derived from environment files. Ingress with TLS termination replaces the Compose reverse proxy, while Readiness Probes enforce dependency ordering previously handled by depends_on. Fork this diagram to customize your own Compose-to-Kubernetes migration, download as .drawio or .svg, and embed in runbooks or documentation.

People also ask

How do I migrate a Docker Compose application with multiple services and a database to Kubernetes?

This diagram maps each Compose service to equivalent Kubernetes resources: the nginx reverse proxy becomes an Ingress with TLS, web and api services become Deployments with ClusterIP Services, and the PostgreSQL database becomes a StatefulSet with PersistentVolumeClaim. Environment variables from .env files are split into ConfigMaps and Secrets, while Readiness Probes replace depends_on ordering.
