Kompose (Kubernetes + Compose)

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.

Use Case

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

$ 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-slave-service.yaml" created      
INFO Kubernetes file "frontend-deployment.yaml" created      
INFO Kubernetes file "redis-master-deployment.yaml" created  
INFO Kubernetes file "redis-slave-deployment.yaml" created 

Other examples are provided in the examples directory.

Installation

We have multiple ways to install Kompose. Our prefered method is downloading the binary from the latest GitHub release.

Our entire list of installation methods are located in our installation.md document.

Installation methods:

• Binary (Prefered method)
• Go
• CentOS
• Fedora
• macOS (Homebrew)
• Windows

Binary installation

Kompose is released via GitHub on a three-week cycle, you can see all current releases on the GitHub release page.

Linux and macOS:

# Linux
curl -L https://github.com/kubernetes/kompose/releases/download/v1.4.0/kompose-linux-amd64 -o kompose

# macOS
curl -L https://github.com/kubernetes/kompose/releases/download/v1.4.0/kompose-darwin-amd64 -o kompose

chmod +x kompose
sudo mv ./kompose /usr/local/bin/kompose

Windows:

Download from GitHub and add the binary to your PATH.

Shell autocompletion

We support both Bash and Zsh autocompletion.

# Bash (add to .bashrc for persistence)
source <(kompose completion bash)

# Zsh (add to .zshrc for persistence)
source <(kompose completion zsh)

Development and building of Kompose

Downloading the latest (master) binary

"Nightly" binaries are generated on a per-merge basis and uploaded to Bintray

Linux and macOS:

# Linux 
curl -L https://dl.bintray.com/kompose/kompose/latest/kompose-linux-amd64 -o kompose

# macOS
curl -L https://dl.bintray.com/kompose/kompose/latest/kompose-darwin-amd64 -o kompose

chmod +x kompose
sudo mv ./kompose /usr/local/bin/kompose

Windows:

Download from Bintray and add the binary to your PATH.

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:

$ make bin

Or go build:

$ go build -o kompose main.go

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 main.go

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

$ make cross
