-## Step 3. Deploy Kubernetes
+## Step 3. Define Kubernetes configuration
+
+Kubespray gives you ability to customize Kubernetes instalation, for example define:
+- network plugin
+- container manager
+- kube_apiserver_port
+- kube_pods_subnet
+- all K&s addons configurations, or even define to deploy cluster on hyperscaller like AWS or GCP.
+All of those settings are stored in group vars defined in `inventory/mycluster/group_vars`
+
+For K&s settings look in `inventory/mycluster/group_vars/k8s_cluster/k8s-cluster.yml`
+
+**_NOTE:_** If you noted issues on `TASK [kubernetes/control-plane : Kubeadm | Initialize first master]` in K& deployment, change the port on which API Server will be listening on from 6443 to 8080. By default Kubespray configures kube_control_plane hosts with insecure access to kube-apiserver via port 8080. Refer to [kubespray getting-started](https://github.com/kubernetes-sigs/kubespray/blob/master/docs/getting_started/getting-started.md)

 The Ansible playbooks will take several minutes to finish. After playbook is done, you can check the output. If `failed=0` exists, it means playbook execution is successfully done.
