# Kompose (Kubernetes + Compose)

[![Build Status](https://travis-ci.org/kubernetes-incubator/kompose.svg?branch=master)](https://travis-ci.org/kubernetes-incubator/kompose) [![Join us on Slack](https://s3.eu-central-1.amazonaws.com/ngtuna/join-us-on-slack.png)](https://skippbox.herokuapp.com)

`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

If you have a Docker Compose [`docker-compose.yml`](./examples/docker-compose.yml) or a Docker Distributed Application Bundle [`docker-compose-bundle.dab`](./examples/docker-compose-bundle.dab) file, you can convert it into Kubernetes deployments and services like this:

```console
$ kompose --bundle docker-compose-bundle.dab convert
WARN[0000]: Unsupported key networks - ignoring
file "redis-svc.json" created
file "web-svc.json" created
file "web-deployment.json" created
file "redis-deployment.json" created

$ kompose -f docker-compose.yml convert
WARN[0000]: Unsupported key networks - ignoring
file "redis-svc.json" created
file "web-svc.json" created
file "web-deployment.json" created
file "redis-deployment.json" created
```

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

## Installation 

Grab the latest [release](https://github.com/kubernetes-incubator/kompose/releases) for your OS, untar and extract the binary.

Linux example:
```
wget https://github.com/kubernetes-incubator/kompose/releases/download/v0.1.1/kompose_linux-amd64.tar.gz
tar -xvf kompose_linux-amd64.tar.gz --strip 1
sudo mv kompose /usr/local/bin
```

## Bash completion
Running this below command in order to benefit from bash completion

```console
$ PROG=kompose source script/bash_autocomplete
```

## Building

### Building with `go`

- You need `make`
- You need `go` v1.6 or later.
- If your working copy is not in your `GOPATH`, you need to set it accordingly.

You can either build via the Makefile:

```console
$ make binary
```

Or `go build`:

```console
$ go build -tags experimental -o kompose ./cli/main
```

You need `-tags experimental` because the current `bundlefile` package of docker/libcompose is still experimental.

If you have `go` v1.5, it's still good to build `kompose` with the following settings:

```console
$ CGO_ENABLED=0 GO15VENDOREXPERIMENT=1 go build -o kompose -tags experimental ./cli/main
```

To create a multi-platform binary, use the `binary-cross` command via `make`:

```console
$ make binary-cross
```

Incubation of `kompose` into the Kubernetes project is shepherd in the [SIG-APPS](https://github.com/kubernetes/community).

[@ericchiang](https://github.com/ericchiang) is acting as Champion for [incubation](https://github.com/kubernetes/community/blob/master/incubator.md)

We do a bi-weekly community meeting. Here is the link to [agenda doc](https://docs.google.com/document/d/1I5I21Cp_JZ9Az5MgMcu6Hl7m8WQ1Eqk_WeQLHenNom0/edit?usp=sharing).
