Docker Compose vs Kubernetes YAML: Format Comparison

Key differences between the two formats

Feature	Docker Compose	Kubernetes YAML
Container orchestration	Single host, simple multi-container apps	Multi-host clusters, enterprise-grade orchestration
Service discovery	Automatic within compose network	Service objects with ClusterIP/NodePort/LoadBalancer
Storage	Named volumes and bind mounts	PersistentVolumes, PersistentVolumeClaims, StorageClasses
Networking	Bridge networks, custom networks	Services, Ingress controllers, NetworkPolicies
Scaling	Manual replica count per service	Horizontal Pod Autoscaler, Vertical Pod Autoscaler
Health checks	healthcheck directive	livenessProbe, readinessProbe, startupProbe
Configuration	environment variables, .env files	ConfigMaps, Secrets, environment variables
Resource limits	deploy.resources (Compose 3.x)	resources.requests and resources.limits

When to Convert

Common scenarios where this conversion is useful

How to Convert Docker Compose to Kubernetes YAML

1

Upload your Docker Compose file

Drag and drop your docker-compose.yml or compose.yaml file onto the converter, or click to browse your files. Any Compose version is supported.
2

Automatic Kubernetes manifest generation

Your Compose services are converted to Kubernetes Deployments, Services, ConfigMaps, and other resources instantly in your browser. No data is sent to any server.
3

Download the Kubernetes YAML bundle

Click Download to save your converted Kubernetes manifests as a single YAML file with proper resource separation using --- delimiters.

Frequently Asked Questions

Does the converter handle all Docker Compose features?

The converter supports most common Compose features including services, volumes, networks, environment variables, port mappings, and resource limits. Some Docker-specific features like privileged mode or device mappings may require manual adjustment for Kubernetes.

How are Docker Compose services mapped to Kubernetes resources?

Services become Deployments with corresponding Service objects. Named volumes become PersistentVolumeClaims. Networks become Service selectors. Environment variables are preserved, and secrets can be extracted to ConfigMaps.

Are my configuration files uploaded to a server?

No. The entire conversion happens in your browser using JavaScript. Your Docker Compose files never leave your device, making it safe for sensitive infrastructure configurations.

Can I convert Docker Compose with external volumes?

Yes. External volumes are converted to PersistentVolumeClaims with appropriate storage requests. You may need to configure StorageClasses in your Kubernetes cluster to match your storage requirements.

How are port mappings handled in the conversion?

Docker Compose port mappings are converted to Kubernetes Service objects with appropriate port and targetPort configurations. LoadBalancer type is used for exposed ports, ClusterIP for internal services.

Does the converter generate Ingress resources?

Basic Ingress resources are generated for services with exposed HTTP ports (80, 8080, 3000, etc.). You'll need to configure your Ingress controller and update host rules for your specific domain requirements.

How are environment variables and secrets handled?

Environment variables are preserved in the Deployment spec. Sensitive values (containing 'password', 'secret', 'key') are automatically extracted to a ConfigMap for easier Kubernetes secret management.

Can I convert Compose files with multiple networks?

Yes. Multiple networks are converted to appropriate Service selectors and NetworkPolicy resources where applicable. Inter-service communication is maintained through Kubernetes Service discovery.

How are resource limits converted?

Docker Compose deploy.resources are mapped to Kubernetes resources.requests and resources.limits. Memory and CPU constraints are preserved with appropriate Kubernetes formatting.

Does the converter handle health checks?

Yes. Docker Compose healthcheck directives are converted to Kubernetes livenessProbe and readinessProbe configurations with appropriate HTTP, TCP, or command-based checks.

Is this suitable for production deployments?

The converter generates a solid foundation, but you should review and customize the output for production. Add appropriate labels, annotations, resource quotas, and security contexts based on your cluster requirements.

Is this free to use?

Yes, completely free with no limits on file size or number of conversions. No account required.
