TL;DR
Kompose converts Docker Compose files into Kubernetes Deployments, Services, and PersistentVolumeClaims with one command.
§01

What it is

Kompose is an official Kubernetes tool that translates Docker Compose files into Kubernetes resource definitions. It generates Deployments, Services, PersistentVolumeClaims, and ConfigMaps from your existing docker-compose.yml, giving you a fast migration path from Compose to Kubernetes.

It targets DevOps engineers and developers migrating containerized applications from Docker Compose to Kubernetes who want to avoid manually writing YAML manifests.

§02

How it saves time or tokens

Kompose automates the tedious translation of Compose service definitions into Kubernetes objects. A single command converts ports, volumes, environment variables, and dependencies into the correct Kubernetes resources. No manual YAML editing required.

§03

How to use

  1. Install Kompose:
brew install kompose
# Or on Linux:
curl -L https://github.com/kubernetes/kompose/releases/latest/download/kompose-linux-amd64 -o kompose
chmod +x kompose && sudo mv kompose /usr/local/bin/
  1. Convert your Docker Compose file:
kompose convert
  1. Apply the generated manifests:
kubectl apply -f .
§04

Example

# Install
brew install kompose

# Convert docker-compose.yml to Kubernetes YAML
kompose convert

# Or convert and apply directly
kompose up

# Generate Helm chart instead
kompose convert -c

# Specify output format
kompose convert -o k8s-manifests.yaml

Key considerations

When evaluating Kompose for your workflow, consider the following factors. First, assess whether your team has the technical prerequisites to adopt this tool effectively. Second, evaluate the maintenance burden against the productivity gains. Third, check community activity and documentation quality to ensure long-term viability. Integration with your existing toolchain matters more than feature count alone. Start with a small pilot project before rolling out across the organization. Monitor resource usage during the initial adoption phase to identify bottlenecks early. Document your configuration decisions so team members can onboard independently.

§06

Common pitfalls

  • Not all Docker Compose features have Kubernetes equivalents; depends_on, build, and some network modes are ignored or partially converted.
  • Volume mounts are converted to PVCs but may need manual storage class configuration for your cluster.
  • Generated manifests are a starting point; production deployments need resource limits, health checks, and security contexts added manually.

Preguntas frecuentes

Does Kompose support Docker Compose v3?+

Yes. Kompose supports Compose file versions 1, 2, and 3. It reads the standard docker-compose.yml format and handles most service definitions across versions.

Can Kompose generate Helm charts?+

Yes. Use 'kompose convert -c' to generate a Helm chart directory instead of flat YAML manifests. This is useful for templated, reusable deployments.

What Kubernetes resources does Kompose create?+

Kompose generates Deployments, Services, PersistentVolumeClaims, and ConfigMaps by default. It maps Compose service ports to Services and volumes to PVCs.

Is Kompose an official Kubernetes project?+

Yes. Kompose is part of the Kubernetes project under the kubernetes GitHub organization. It is maintained by the Kubernetes community.

Can I customize the generated output?+

Yes. Kompose supports labels in your Compose file (kompose.service.type, kompose.volume.size) to control the generated Kubernetes resources. You can also post-process the YAML with kustomize or Helm.
