Docker Compose → Kubernetes Converter

Docker Compose and Kubernetes are both container orchestration tools, but they operate at very different scales. Docker Compose uses a simple docker-compose.yml file to define multi-container applications for local development and small deployments. Kubernetes uses a richer set of resource manifests (Deployments, Services, ConfigMaps, PersistentVolumeClaims) for production-grade container orchestration.

When teams migrate from Docker Compose to Kubernetes — whether moving to production, scaling up, or adopting a cloud-native architecture — they need to translate their Compose files into equivalent Kubernetes manifests. This involves mapping services to Deployments, ports to Services, environment variables to ConfigMaps, named volumes to PersistentVolumeClaims, and more.

This converter parses your docker-compose.yml and generates corresponding Kubernetes YAML manifests automatically. It handles services, ports, environment variables, volumes (both named and host-path), restart policies, commands, and dependency annotations. The output serves as a solid starting point that you can review and customize for production. All processing happens in your browser.

1. Paste your docker-compose.yml — Copy your existing Docker Compose file into the input field. The tool supports version 2.x and 3.x Compose files with common configurations.
2. Or load the example — Click "Load Example" to see a multi-service Compose file (nginx + Node.js API + PostgreSQL) and its Kubernetes conversion.
3. Review the generated manifests — The tool creates Kubernetes Deployments, Services (for exposed ports), ConfigMaps (for environment variables), and PersistentVolumeClaims (for named volumes) automatically.
4. Check the resource count — Badge indicators show the number of services detected and total Kubernetes resources generated.
5. Copy and customize — Click "Copy All" to copy the complete YAML output. Review and adjust resource limits, health checks, ingress rules, and other production settings before deploying.

• Complete resource generation — Generates Deployments, Services (ClusterIP/NodePort), ConfigMaps, and PersistentVolumeClaims from a single Compose file.
• Smart port mapping — Creates ClusterIP Services when host and container ports match, NodePort Services when they differ, with proper port configuration.
• Environment variable handling — Extracts environment variables from both list format (- KEY=value) and map format (KEY: value) into Kubernetes ConfigMaps with envFrom references.
• Volume conversion — Named volumes become PersistentVolumeClaims, host path mounts become hostPath volumes, both with proper volumeMounts in the Pod spec.
• Dependency annotations — depends_on relationships are preserved as comments with guidance to use init containers or readiness probes instead.
• 100% client-side — Your docker-compose.yml never leaves your browser. No server-side parsing or storage.

• Production migration — Migrate local development stacks defined in Docker Compose to Kubernetes clusters for production deployment.
• Learning Kubernetes — Understand how Docker Compose concepts map to Kubernetes resources by seeing the side-by-side conversion.
• Scaffolding K8s manifests — Generate a starting set of Kubernetes YAML files rather than writing Deployments, Services, and ConfigMaps from scratch.
• CI/CD pipeline setup — Convert existing Compose-based workflows to Kubernetes manifests for deployment in CI/CD pipelines targeting K8s clusters.
• Multi-environment deployments — Use the generated manifests as a base and create environment-specific overlays with Kustomize or Helm.
