以下是我的个人观点:

面向配置文件配置 -- 没问题, 配置文件就是用来定义 high-level 的意愿的.

面向配置文件编程 -- 一般是这个系统或者工具设计有问题, 虽然这事儿在整个 
industry 经常发生...

一旦有大量的配置文件，需要编程来动态生成的时候... 最好应该设计成 API 编程, 
而不是捣鼓配置文件.
配置文件是个high-level & weak modeling tool, 编程语言(with function, API) 是
low-level & strong modeling tool.
所以一旦走上了面向配置文件编程的路线，设计的东西就会很 complex, fragile.
比如永远在更新，永远复杂的一逼的各种前端框架 -- 面向 HTML, CSS 配置文件编程.
还有传统 Java 里面那一坨坨的 XML cfgs, 也是这种毛病.

整个 industry 经常重复做错的一件事: 
发明一个  high-level 的, 但是描述能力很弱的抽象工具,
然后因为这个工具 high-level, 捣鼓几下能直接看到效果,
就使劲忽悠大家用, 如果这个工具背景强, 有钱做 market,
这个祸害就扩散开了, 过几年再看... 又会有类似的新祸害出来, 号称可以拯救旧祸害
导致的各种问题...
于是, 整个 industry 就像时尚界一样, 可以这几年流行这个, 那几年流行那个... 
真正 well design 的创新工具到底有多少?


【 在 guvest (我爱你老婆Anna) 的大作中提到: 】
: 写写emacs/vim, 解决这些问题?
: 图灵完备的一大动力是自动化生成配置文件。
: 本来配置文件不是图灵完备的。加上模版和eval就成了正经的coding.
: 如果不熟悉emacs/vim. 可以写写MS word VBA自动产生yaml. Excel也行。

: 你先捏着鼻子配置会儿k8s那一坨坨yaml再说

: 面向配置文件编程, 面向黑盒编程, 面向 stackoverflow 编程    @_@

CKA Simulator Kubernetes 1.22

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
