k8s doc reading index

Introduction

k8s(kubernetes) 是一個容器執行平台
誕生於 google
由於其本身就是 for 大型環境使用, 其功能非常多樣
一般要上手屬實不容易
而也許又出自 google 的手上, 其 doc 還真不是普通的易懂
本系列的誕生有幾個目的

• 為了能讓自己能夠掌握大部分功能:
  等於逼自己學習啦

• 且培養閱讀 official doc 能力:
  k8s 功能非常多, 坊間書籍可能不會包含所有功能
  且要等到出書, 都不知道是幾個月後的事了
  能夠立即了解 new information 是非常重要的

• 官方 doc 排序超級鳥:
  於果你跟我一樣照著 k8s 官方的排序閱讀
  你應該會跟一樣一頭霧腦的
  以下順序經過我重新調整過
  希望能夠讓讀者們在學習 k8s 時能夠得心應手

在本系列開始前
先給大家一個觀念
k8s 跟 docker 都需要使用 container runtime 去執行容器
而他們基本都使用 containerd
換句話說 在一定程度上是很像的
只是 k8s 是 for 大型環境使用
docker 偏向小型環境
什麼意思呢？
舉例來說
如果你今天只是要載 2~3 位朋友出門
你可能會開著自排小客車出門: 你只要會打 D 檔/踩油門/踩煞車
docker 就像小客車概念

如果你今天只是要載 10~20 位朋友出門
你會需要開大客車: 你得學會 手動排檔/車輛保養/轉彎半徑…及其餘知識
k8s 就像大客車概念

如果你不會開小客車, 那開大客車就不用想了 因為你沒有基本能力
就跟台灣考駕照制度一樣
考大客車駕照前 必須先考小型車駕照, 這是基本門檻

回到這裡
若還沒了解 docker 的話, 雖然沒人會阻止你學習 k8s
但一定會學得很痛苦, 這裡一定不會再去講 container 的基本知識
而且基本工太差, 很容易就學歪掉
請務必把學習 docker 當成學習 k8s 的基本門檻
等 docker 學的差不多後, 再回來閱讀此系列

這個類別是建議所有人都該學會 k8s 的知識
原文可會講的太過深入, 我認為不必了解的東西我就不會做說明
