Kompose (Kubernetes + Compose)
in #kompose channel
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
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 Unsupported key networks - ignoring
file "redis-svc.yaml" created
file "web-svc.yaml" created
file "web-deployment.yaml" created
file "redis-deployment.yaml" created
$ kompose -f docker-compose.yml convert
WARN Unsupported key networks - ignoring
file "redis-svc.yaml" created
file "web-svc.yaml" created
file "web-deployment.yaml" created
file "redis-deployment.yaml" created
Other examples are provided in the examples directory.

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:
$ 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
