microk8s和k3s
MicroK8s与K3s都是基于Kubernetes的轻量级发行版，主要面向工作站、边缘计算、物联网等应用场景，但二者也有比较大的区别。主要区别MicroK8s主要将一些扩展件集成到系统中，而K3s却将很多扩展件独立出来。虽然MicroK8s与K3s都能支持ARM体系的低功耗计算，但是MicroK8s主打使用方便性，也更适合开发团队使用，而K3s主打轻量化，更适合低功耗的小型化无人值守的自动化系统使用。MicroK8s的集群管理内核与Kubernetes标准版的容器镜像是完全一样的，而K3s的内核进行了一些修改，部分模块可能由于兼容性问题无法运...
关于JS中this的指向，这里有讲得比较清楚的，收藏一下
JS中this关键字很常见，但是它似乎变幻莫测，让人抓狂。这篇文章就来揭示其中的奥秘。借助阮一峰老师的话：它代表函数运行时，自动生成的一个内部对象，只能在函数内部使用。这句话看似平常，可是要非常注意三个字：“运行时”，这说明this关键字只与函数的执行环境有关，而与声明环境没有关系。也就是这个this到底代表的是什么对象要等到函数运行时才知道，有点类似函数定义时的参数列表只在函数调用时才传入真正的对象。理解了这一点对后面this关键字规律的掌握有很大帮助。this关键字虽然会根据环境变化，但是...
