Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a platform for managing and deploying containerized applications at scale. Kubernetes architecture is based on a client-server model, where the client is the Kubernetes API server and the server is the Kubernetes cluster. The Kubernetes API server is responsible for managing the state of the Kubernetes cluster, while the Kubernetes cluster is responsible for running the containerized applications.
Kubernetes architecture is designed to be highly scalable and fault-tolerant. It is composed of several components that work together to provide a robust and reliable platform for running containerized applications. The main components of Kubernetes architecture are:
1. Master node: The master node is responsible for managing the state of the Kubernetes cluster. It runs several components, including the Kubernetes API server, etcd, and the Kubernetes controller manager.
2. Worker node: The worker node is responsible for running the containerized applications. It runs several components, including the Kubernetes kubelet and the Kubernetes proxy.
3. etcd: etcd is a distributed key-value store that is used to store the state of the Kubernetes cluster. It is used by the Kubernetes API server and the Kubernetes controller manager to store the state of the cluster.
4. Kubernetes API server: The Kubernetes API server is responsible for managing the state of the Kubernetes cluster. It exposes the Kubernetes API, which is used by the Kubernetes command-line interface (CLI) and other Kubernetes components to interact with the Kubernetes cluster.
5. Kubernetes controller manager: The Kubernetes controller manager is responsible for managing the various controllers that are used to manage the state of the Kubernetes cluster. It runs several controllers, including the replication controller, the endpoint controller, and the service account and token controllers.
6. Kubernetes kubelet: The Kubernetes kubelet is responsible for running the containerized applications on the worker node. It communicates with the Kubernetes API server to receive instructions on which containers to run and how to run them.
7. Kubernetes proxy: The Kubernetes proxy is responsible for routing network traffic to the appropriate container on the worker node. It runs on each worker node and communicates with the Kubernetes API server to receive instructions on how to route network traffic.
