K8S

【Kubernetes/K8S】 Service Introduction

Service supports access to a group of Pods in Kubernetes through the network, and the service selects Pods based on labels. When making a network request to the service, it will select all Pods in the cluster that matches the service selector, select one of them, and forward the network request to it.

Basic Concepts of Kubernetes RBAC

When we use kind K8s to create various objects, the default user is the admin user, which has all the permissions to manage the cluster. In a real multi-user scenario, we cannot all use the admin user, and we need to assign appropriate permissions to different users according to the situation. .
