Kubermatic Kubernetes Platform is in an open source project to centrally manage the global automation of thousands of Kubernetes clusters across multicloud, on-prem and edge with unparalleled density and resilience.

All user documentation is available at the Kubermatic Kubernetes Platform docs website.

There are two editions of Kubermatic Kubernetes Platform:

Kubermatic Kubernetes Platform Community Edition (CE) is available freely under the Apache License, Version 2.0. Kubermatic Kubernetes Platform Enterprise Edition (EE) includes premium features that are most useful for organizations with large-scale Kubernetes installations with more than 50 clusters. To access the Enterprise Edition and get official support please become a subscriber.

See the LICENSE file for licensing information as it pertains to files in this repository.

We strongly recommend that you use an official release of Kubermatic Kubernetes Platform. Follow the instructions under the Installation section of our documentation to get started.

The code and sample YAML files in the main branch of the kubermatic repository are under active development and are not guaranteed to be stable. Use them at your own risk!

The documentation provides a getting started guide, plus information about building from source, architecture, extending kubermatic, and more.

Please use the version selector at the top of the site to ensure you are using the appropriate documentation for your version of kubermatic.

If you encounter issues file an issue or talk to us on the #kubermatic channel on the Kubermatic Community Slack (click here to join).

There are a couple of scripts in the hacks directory to aid in running the components locally for testing purposes.

In order to instrument the seed-controller to allow for a local user-cluster-controller-manager, you need to add a worker-name label with your local machine's name as its value. Additionally, you need to scale down the already running deployment.

# Using a kubeconfig, which points to the seed-cluster
export cluster_id="<id-of-your-user-cluster>"
kubectl label cluster ${cluster_id} worker-name=$(uname -n)
kubectl scale deployment -n cluster-${cluster_id} usercluster-controller --replicas=0

Afterwards, you can start your local user-cluster-controller-manager.

# Using a kubeconfig, which points to the seed-cluster
./hack/run-user-cluster-controller-manager.sh

./hack/run-seed-controller-manager.sh

./hack/run-master-controller-manager.sh

Before every push, make sure you run:

make lint

make test

The Kubernetes code-generator tool does not work outside of GOPATH (upstream issue), so the script below will automatically run the code generation in a Docker container.

hack/update-codegen.sh
