`kompose` is a tool to help users who are familiar with `docker-compose` move to [Kubernetes](http://kubernetes.io). `kompose` takes a Docker Compose file and translates it into Kubernetes resources.

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

## Use Case

Convert [`docker-compose.yaml`](https://raw.githubusercontent.com/kubernetes/kompose/main/examples/docker-compose.yaml) into Kubernetes deployments and services with one simple command:

```sh
$ kompose convert -f docker-compose.yaml
INFO Kubernetes file "frontend-service.yaml" created
INFO Kubernetes file "redis-master-service.yaml" created
INFO Kubernetes file "redis-replica-service.yaml" created
INFO Kubernetes file "frontend-deployment.yaml" created
INFO Kubernetes file "redis-master-deployment.yaml" created
INFO Kubernetes file "redis-replica-deployment.yaml" created
```

Other examples are provided in the _examples_ [directory](./examples).
