Kubernetes平台比較：Red Hat OpenShift、SUSE Rancher及 Canonical Kubernetes 如何為貴企業選擇合適的Kubernetes發行版本 2022年7月 執行摘要 採用容器優先方法的企業，將能享有無可比擬的機會，協助提升效率及資源使用 率、加強安全性、導入自動化及加速創新；因此Gartner預測將有75%的全球組 織，在2022年之前於正 感到驚訝。1 Kubernetes已經成為管理容器化工作負載和服務的頂尖開放原始碼平台，不過 Kubernetes生態系統既龐大又複雜，不但有許多不同版本的Kubernetes可供選 擇，此外也難以瞭解哪種版本最適合組織的特定需求。 本白皮書的目標是因應這項挑戰，提供撰寫本文時Kubernetes版圖的當下狀態， 並比較三種企業級的Kubernetes發行版本，分別是Canonical Kubernetes、 以表格提供總結分數。Canonical Kubernetes證明成為最具彈性、優勢及成本 效益的發行版本。 1. https://www.gartner.com/en/newsroom/press-releases/2020-06-25-gartner-forecasts-strong-revenue-growth-for-global-co 企業Kubernetes的關鍵考量因素 1.

第1 章 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 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 這個前輩的肩膀上，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。 1-9 1.3 從一個不簡單的 Hello World 範例說起 瀏覽器訪問 讀 寫 虛擬機 Kubernetes 服務 圖 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。 首 先 為 redis-master 服 務 建 立 一 個 名 為
