Development environment

mkdir -p $(go env GOPATH)/src/k8c.io
cd $(go env GOPATH)/src/k8c.io
git clone [email protected]:kubermatic/kubermatic
cd kubermatic

Or alternatively:

go get k8c.io/kubermatic

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

You can create a cluster via the UI at https://dev.kubermatic.io, then use kubectl to add a worker-name=<<hostname-of-your-laptop>> label to the cluster. This will make your locally running controllers manage the cluster.

Running locally

kubermatic-api

./hack/run-api.sh

seed-controller-manager

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

master-controller-manager

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

Run linters

Before every push, make sure you run:

make lint

Run tests

make test

Update code generation

Kuberneres code-generator tool does not work outside of GOPATH see, if you followed the recommendation and cloned your repository at $(go env GOPATH)/src/k8c.io you can run the following command:

hack/update-codegen.sh

Otherwise run the following (requires Docker):

make update-codegen-in-docker
