This post provides an overview of Admission Controllers in Kubernetes, including their implementation and usage.

规范的 K8s APIVersion 往往会经历由 alpha 到 beta 最后到 stable 的过程，API 转换就成了应有之义。

apiserver-runtime 本身也是基于 k8s.io/apiserver 提供增强。

理解 K8s apiserver 的最好方式就是自己动手实现同款

彻底而全面的梳理，甚至提供了复制即用的脚本和镜像…

全图文展示 apiserver aggregation 原理，彻底搞懂 APIService 和 custom apiserver 认证授权 (authn, authz)

本文实现了一个符合 Kubernetes REST 风格的极简 apiserver，代码量只有 500 行左右。

K8s CustomResourceDefinition (CRD) 为使用者提供了开箱即用的 REST API 拓展能力。

Setting up a Kubernetes cluster with a newly deployed metrics server often results in the following error message: Failed to scrape node, err=Get https://172.18.0.3:10250/metrics/resource: x509: cannot validate certificate for 172.18.0.3 because it doesn't

HTTP REST 缓存简述

HTTP REST API 通用设计思路

HTTP range request is a widely used feature when it comes to file resource.

Running application in container as PID 1 is quite common today, shutdown application responsively and gracefully is hard.

在 SDN 网络环境中，由于 docker0 bridge MTU 1500 大于 Host MTU（如 1400），网络会出现好像没问题但实际有问题的情况。
