README

Kompose (Kubernetes + Compose)

kompose is a tool to help users who are familiar with docker-compose move to Kubernetes. kompose takes a Compose Specification file and translates it into Kubernetes resources.

kompose is a convenience tool to go from local Compose environment to managing your application with Kubernetes. Transformation of the Compose Specification format to Kubernetes resources manifest may not be exact, but it helps tremendously when first deploying an application on Kubernetes.

Use Case

Convert compose.yaml into Kubernetes deployments and services with one simple command:

$ kompose convert -f compose.yaml
INFO Kubernetes file "frontend-service.yaml" created
INFO Kubernetes file "redis-leader-service.yaml" created
INFO Kubernetes file "redis-replica-service.yaml" created
INFO Kubernetes file "frontend-deployment.yaml" created
INFO Kubernetes file "redis-leader-deployment.yaml" created
INFO Kubernetes file "redis-replica-deployment.yaml" created

Other examples are provided in the examples directory.
