Docker Compose to Kubernetes Converter

Docker Compose is perfect for development and simple deployments. Kubernetes provides production-grade features like auto-scaling, rolling updates, service discovery, secrets management, and multi-cluster orchestration. It’s designed for high-availability, large-scale applications.

Kubernetes has a different networking model. All pods can communicate with each other by default within a cluster. Custom Docker Compose networks become Kubernetes Services and NetworkPolicies for traffic control. The built-in DNS and service discovery replace docker-compose networking.

Named volumes become PersistentVolumeClaims (PVCs) that can be dynamically provisioned. Bind mounts are discouraged in production and become hostPath volumes (dev only) or proper PVCs. This provides better portability and integration with cloud storage providers.

Kubernetes doesn’t have direct depends_on equivalent. Instead, use init containers for dependencies, readiness probes to ensure services are ready before receiving traffic, or application-level retry logic. This makes applications more resilient and cloud-native.

This tool provides a solid starting point, but production deployments need additional considerations: resource limits, security contexts, RBAC, ingress configuration, monitoring, logging, backup strategies, and environment-specific settings. Always review and customize the output.
