`kompose` is a tool to help users who are familiar with `docker-compose` move to [Kubernetes](http://kubernetes.io). `kompose` takes a [Compose Specification](https://compose-spec.io/) 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](https://compose-spec.io/) 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`](https://raw.githubusercontent.com/kubernetes/kompose/main/examples/compose.yaml) into Kubernetes deployments and services with one simple command:

```sh
$ 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](./examples).
