# Kubernetes 入門 ### 1.1 Kubernetes 是什麼？ Kubernetes 是什麼？ 首先，它是一個全新的基於容器技術的分散式架構解決方案。這個方案雖然還很新，但它是 Google 十幾年來大規模應用容器技術的經驗累積和演進的一個重要成果。確切地說，Kubernetes 是 Google 嚴格保密十幾年的秘密武器——Borg 的開源專案版本。Borg 是 Google 的內部設計，所以外界一直無法瞭解它的相關資訊。直到 2015 年 4 月，傳聞許久的 Borg 論文伴隨著 Kubernetes 的發布宣傳被 Google 首度公開，大家才得以瞭解它的更多內幕。正因站在 Borg 這個前輩的肩勝上，吸取了 Borg 過去十年間的經驗與教訓，所以 Kubernetes 一經開源就一鳴驚人，並迅速席捲了容器技術領域。  圖 1.3 Kubernetes 部署架構圖 #### 1.3.1 建立 redis-master Pod 及服務 我們可以先定義 Service，然後再定義一個 RC 來建立和控制相對應的 Pod，或者先定義 RC 來建立 Pod，然後定義與其關聯的 Service，這兩種方式最終的結果都一樣，這裡我們採用後面這種方式。
