### Unix Accounts for Kubernetes Components

During installation, Embedded Cluster automatically creates the following Unix accounts that are required by internal Kubernetes components:

* **etcd**: Used by the Kubernetes etcd database, which stores cluster state.
* **konnectivity-server**: Used by the Konnectivity service, which facilitates secure communication between internal components.
* **kube-apiserver**: Used by the Kubernetes API server.
* **kube-scheduler**: Used by the Kubernetes scheduler to schedule workloads such as pods.

No action is required to create these roles. Removing them will make the cluster non-functional.

For more information about the internal Kubernetes components, see [Kubernetes Components](https://kubernetes.io/docs/concepts/overview/components/) in the Kubernetes documentation.

For more information about the Konnectivity service, see [Set up Konnectivity service](https://kubernetes.io/docs/tasks/extend-kubernetes/setup-konnectivity/) in the Kubernetes documentation.
