- Creation of worker nodes on AWS, Digitalocean, Openstack, Azure, Google Cloud Platform, VMWare Vsphere, Linode, Hetzner cloud and Kubevirt (experimental)
- Using Ubuntu, Flatcar or CentOS 7 distributions (not all distributions work on all providers)
machine-controller tries to follow the Kubernetes version support policy as close as possible.
Currently supported K8S versions are:
- 1.24
- 1.23
- 1.22
- 1.21
- Master creation (Not planned at the moment)
make deploy
# edit examples/$cloudprovider-machinedeployment.yaml & create the machineDeployment
kubectl create -f examples/$cloudprovider-machinedeployment.yaml
By default the controller looks for a cluster-info
ConfigMap within the kube-public
Namespace.
If one is found which contains a minimal kubeconfig (kubeadm cluster have them by default), this kubeconfig will be used for the node bootstrapping.
The kubeconfig only needs to contain two things:
- CA-Data
- The public endpoint for the Apiserver
If no ConfigMap can be found:
CA-data
The CA will be loaded from the passed kubeconfig when running outside the cluster or from /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
when running inside the cluster.
Apiserver endpoint
The first endpoint from the kubernetes endpoints will be taken. kubectl get endpoints kubernetes -o yaml

Simply run make test-unit
This project provides easy to use e2e testing using Hetzner cloud. To run the e2e tests locally, the following steps are required:
- Populate the environment variable
HZ_E2E_TOKEN
with a valid Hetzner cloud token - Run
make e2e-cluster
to get a simple kubeadm cluster on Hetzner - Run
hack/run-machine-controller.sh
to locally run the machine-controller for your freshly created cluster
If you want to use an existing cluster to test against, you can simply set the KUBECONFIG
environment variable.
In this case, first make sure that a kubeconfig created by make e2e-cluster
at $(go env GOPATH)/src/github.com/kubermatic/machine-controller/.kubeconfig
doesn't exist, since the tests will default to this hardcoded path and only use the env var as fallback.
Now you can either
- Run the tests for all providers via
go test -race -tags=e2e -parallel 240 -v -timeout 30m ./test/e2e/... -identifier $USER
- Check
test/e2e/provisioning/all_e2e_test.go
for the available tests, then run only a specific one viago test -race -tags=e2e -parallel 24 -v -timeout 20m ./test/e2e/... -identifier $USER -run $TESTNAME
Note: All e2e tests require corresponding credentials to be present, check
test/e2e/provisioning/all_e2e_test.go
for details
Note: After finishing testing, please clean up after yourself:
- Execute
./test/tools/integration/cleanup_machines.sh
while the machine-controller is still running - Execute
make e2e-destroy
to clean up the test control plane
You can also insert your ssh key into the created instances by editing the manifests in
test/e2e/provisioning/testdata/
