# Kubernetes CoreOS cluster
With this tutorial one creates a Kubernetes CoreOS cluster containing of one
master and three minions (workers) running on `192.168.10.1`-`192.168.10.4`.
For working correctly you need to create the directory addressed as `POOL_PATH` in
`util.sh`:
```
$ sudo mkdir /var/lib/libvirt/images/kubernetes
$ sudo chown -R $USER:$USER /var/lib/libvirt/images/kubernetes/
```
Then we follow the instructions in the main `kubernetes` directory.
For debugging set `export UTIL_SH_DEBUG=1`.
```
$ export KUBERNETES_PROVIDER=libvirt-coreos
$ make release-skip-tests
$ ./cluster/kube-up.sh
```
To bring the cluster down again, execute:
```
$ ./cluster/kube-down.sh
```
Have fun!
