What is Docker Compose to Kubernetes Converter?
A migration tool that transforms your Docker Compose YAML files into production-ready Kubernetes manifests. This converter automatically generates Deployments, Services, ConfigMaps, Secrets, and PersistentVolumeClaims from your Compose configuration, making it easy to move your containerized applications from Docker Compose to Kubernetes orchestration.
The tool understands Compose v3+ syntax and translates services, volumes, networks, environment variables, and port mappings into their Kubernetes equivalents. It handles common patterns like replica counts, resource limits, health checks, and volume mounts while maintaining your application's structure. All conversion happens client-side in your browser for complete privacy and security.
Why Use Docker Compose to Kubernetes Converter?
Manually converting Docker Compose to Kubernetes is tedious and error-prone, requiring deep knowledge of both systems. This tool automates the translation, handles the syntax differences, and generates production-grade Kubernetes YAML that follows best practices. It dramatically reduces migration time from days to minutes and helps teams adopt Kubernetes faster.
Development teams use this to move local Compose setups to Kubernetes clusters, DevOps engineers use it to standardize deployments across environments, and platform teams use it to help developers adopt Kubernetes without learning all the YAML syntax upfront. The tool ensures consistency and reduces human error in migrations.
Common Use Cases
Production Migration: Convert development docker-compose.yml files into Kubernetes manifests ready for staging and production cluster deployments with proper Deployments and Services.
Learning Kubernetes: Understand how Docker Compose concepts map to Kubernetes by seeing the direct translation of services, volumes, and networks into K8s resources.
Multi-Environment Deployment: Generate base Kubernetes manifests from Compose files, then customize them with Kustomize or Helm for different environments (dev/staging/prod).
CI/CD Automation: Automatically convert Compose files to Kubernetes manifests in your deployment pipeline for consistent infrastructure-as-code practices.
Microservices Migration: Migrate multi-container Compose applications to Kubernetes microservices architecture with proper service discovery and networking.
How to Use Docker Compose to Kubernetes Converter
Paste your docker-compose.yml content into the input field and the tool will automatically generate the equivalent Kubernetes manifests. The output includes separate YAML documents for each resource type (Deployments, Services, ConfigMaps, PVCs) that you can apply directly to your cluster with kubectl apply.
The converter handles most common Compose features including service definitions, volume mounts, environment variables, port mappings, restart policies, and health checks. Each generated manifest follows Kubernetes best practices with proper labels, selectors, and resource organization. Review the output and adjust resource limits, replicas, or storage classes as needed for your production environment.
Frequently Asked Questions
Q: What Docker Compose features are supported? A: The converter supports services, volumes, networks, environment variables, ports, labels, restart policies, health checks, and resource limits. Some advanced features like build contexts or dependencies may require manual configuration.
Q: Can it handle multi-service applications? A: Yes! The tool converts each service in your docker-compose.yml into a separate Kubernetes Deployment and Service, maintaining the relationships and networking between services.
Q: What Kubernetes version does it target? A: The generated manifests use Kubernetes API versions compatible with K8s 1.19+, including apps/v1 for Deployments and v1 for Services and ConfigMaps.
Q: Do I need to modify the output? A: The output is production-ready for basic cases, but you may want to customize resource limits, replica counts, storage classes, ingress rules, or namespace configurations based on your specific cluster setup.
Q: How are volumes handled? A: Named volumes become PersistentVolumeClaims, bind mounts become HostPath volumes (with warnings), and tmpfs mounts become emptyDir volumes. You'll need to configure your StorageClass for PVCs.
Q: Is my Compose file data secure? A: Yes, all conversion happens entirely in your browser. Your docker-compose.yml is never sent to any server, stored, or logged. It's completely private.
