K8s Architecture

The worker nodes communicate with the master node to report the state of the node and the containers running on it, and they receive instructions from the master node on which containers to run and how to manage them. Together, the master and worker nodes work together to manage the state of the cluster and ensure that the desired state is achieved.

1. Kubernetes Services: Services are an abstraction layer for pods, which allow you to access pods by a stable network IP and a port.
2. Ingress: An Ingress is a collection of rules that allow inbound connections to reach the cluster services.
3. Volumes: Volumes are used to provide persistent storage for pods, and they can be backed by various types of storage, such as local storage, NFS, or cloud-based storage.
4. Namespaces: Namespaces are used to partition resources in a cluster and can be used to isolate resources for different environments, teams, or projects.

This is a high-level overview of a Kubernetes architecture, and there are many more components and features that can be added to the system depending on the use case. Kubernetes is an extensible platform, new features and functionalities are added regularly.
