kompose is a tool to help users who are familiar with docker-compose move to Kubernetes. 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.

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

$ 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 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.

Grab the latest release for your OS, untar and extract the binary.

Linux example:

wget https://github.com/skippbox/kompose/releases/download/v0.1.0/kompose_linux-amd64.tar.gz
tar -xvf kompose_linux-amd64.tar.gz --strip 1
sudo mv kompose /usr/local/bin

Running this below command in order to benefit from bash completion

$ PROG=kompose source script/bash_autocomplete

• 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:

$ make binary

Or go build:

$ 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:

$ 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:

$ make binary-cross

kompose is a work in progress, we will see how far it takes us. We welcome any pull request to make it even better. If you find any issues, please file it.
