Understanding Python
Ok, perhaps I jest. As a Python instructor, understanding decorators is a topic I find students consistently struggle with upon first exposure. That’s because decorators are hard to understand! Getting decorators requires understanding several functional programming concepts as well as feeling comfortable with some unique features of Python’s function definition and function calling syntax. Using decorators is easy (see Section 10)! But writing them
Kubernetes stateful set讲解以及一个基于postgreSQL的具体例子
Stateful Set是Kubernetes 1.9版本新引入的一个概念，用于管理有状态的应用。Kubernetes官方文档：https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of these Pods.Like a Deployment, a StatefulSet manages Pods that are based on an identical container spec. Unlike a Deployment, a StatefulSet maintains a sticky identity for each of their Pods. These pods are create
『中级篇』k8s重要的Deployment（64）
之前介绍了，pod，ReplicationController，ReplicaSet。这次主要说下Deoloyments。源码：https://github.com/limingios/docker/tree/master/No.9 官方介绍 https://kubernetes.io/docs/concepts/workloads/controllers/deployment/ Deployment为Pod和Replica Set提供声明式更新。你只需要在 Deployment 中描述您想要的目标状态是什么，Deployment controller 就会帮您将 Pod 和ReplicaSet 的实际状态改变到您的目标状态。您可以定义一个全新的 Deployment 来创建 ReplicaSet 或
