依赖注入是目前很多优秀框架都在使用的一个设计模式。 Dependency Injection 常常简称为：DI。它是实现控制反转（Inversion of Control – IoC）的一个模式。
在各种大工程中少不了各种测试，其中 TDD 就是非常流行的一种，在前端开发中用的比较多的 Jest[1] 就是一种，在 Golang 开发命令行工具的时候也是需要 DI 这种模式来实现命令行测试的。因为传统的测试室获取不到命令行的输入输出的。
基准测试是对计算机系统的性能的测试。
在程序中，基准测试，是一种测试代码性能的方法；比如有一个问题你有多种不同的方案，你想选择一种性能最好的方案，那么你就需要基准测试。
SQLite[21] 是一个进程内的库，实现了自给自足的、无服务器的、零配置的、事务性的 SQL 数据库引擎。它是一个零配置的数据库，这意味着与其他数据库一样，你不需要在系统中配置。在 Golang 中使用 SQLLite 也相当简单，只需要安装 SQLLite 的 Golang 包即可使用； Golang 就不多介绍了，能看到这个肯定对 Golang[22] 有一定的了解。

Your Kubernetes control-plane has initialized successfully!
To start using your cluster, you need to run the following as a regular user:
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/
Then you can join any number of worker nodes by running the following on each as root:
kubeadm join 192.168.33.10:6443 --token z1uxfl.z8l2uo9v8x3dtdcu \

在搭建私有云环境时，我们需要将我们打包的镜像存储在局域网内，而不是把镜像推送到 hub.docker.com；一方面是因为安全问题，另一方面在局域网内存储，网速炒鸡快。当然对于私有云搭建，在本地搭建镜像仓库那是必须的。接下来，对我安装 Harbor 做一个记录。

我们大多数情况下用到的包都是存放在 npmjs.com[1] 这个网站上的，只要我们安装了 Node，我们就可以使用 Node 自带的 npm 包来下载你需要的包；但有时候我们想让我们自己的包或者库私有，哪怎么办呢？很多人就会想到自己搭一个私服，比如 Nexus Repository Manager [2] 和 sinopia[3] ; 虽然搭建起来不是很困难，尤其是 sinopia 就是一个 npm 包，安装灰常简单，但是都需要一台服务器，一台服务。.. 一台服。.. 一台。.. 一。..
