# Kubernetes
## Kubernetes Cluster Architecture:
## Kube Master Node Components (Control plane)
| Component | Description |
| ---------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **kube-apiserver** | This component exposes Kubernetes API to users allowing them to create API resources, run applications, and configure various parameters of the cluster. |
| **Etcd** | This is a data store used by Kubernetes to store all information about the cluster. It’s critical for keeping everything up to date. |
| **kube-scheduler** | This component is responsible for scheduling user workloads on the right infrastructure. When scheduling applications, kube-scheduler considers various factors such as available node resources, node health, and availability, as well as user-defined constraints. |
| **kube-controller-manager** | The component that manages API objects created by users. It makes sure that the actual state of the cluster always matches the desired state. |
| **cloud-controller-manager (opt)** | This component embraces various controllers, all of which interact with the cloud providers’ APIs. |
## Kube Worker Node Components
| Component | Description |
| --------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **kubelet** | The kubelet is the primary “node agent” that runs on each node & manages the containers/pods running on each node |
| **Container Runtime** | A container runtime is software that executes containers and manages container images on a node. |
| **kube-proxy (opt)** | kube-proxy is a network proxy that runs on each node in your cluster. kube-proxy maintains network rules on nodes. These network rules allow network communication to your Pods from network sessions inside or outside of your cluster. |
