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 redis-master 的 RC 定 義 檔：redis-master- controller PREROUTING 鏈 POSTROUTING 鏈 POSTROUTING 鏈 INPUT 鏈 OUTPUT 鏈 OUTPUT 鏈 FORW/ARD 鏈 FORW/ARD 鏈 INPUT 鏈 filter 表 nat 表 mangle 表 raw 表 OUTPUT 鏈 Iptables 防火牆預設的規則表、鏈結構 第一條規則 第二條規則 第三條規則 圖 2.23 四種掛接點的規則表 當 資源緊張或工作負載降低而需要減少服務實例數的情形。此時可以利用命令 kubectl scale rc 來完成這些任務。以 redis-slave RC 為例，已定義的最初抄本數量為 2，透 過執行下面的命令將 redis-slave RC 控制的 Pod 抄本數量從初始的 2 更新為 3： $ kubectl scale rc redis-slave --replicas=3 scaled 4-52 Kubernetes

資料三部分，如圖 2‑15 所示。 圖 2‑15 演算法使用的相關空間 相關程式碼如下： use std::rc::Rc; use std::cell::RefCell; /* 結構體 */ struct Node { val: i32, next: Option<Rc>>, } /* 建立 Node 結構體 */ impl Node { fn new(val: hello‑algo.com 48 // === File: space_complexity.rs === /* 指數階（建立滿二元樹） */ fn build_tree(n: i32) -> Option<Rc>> { if n == 0 { return None; }; let root = TreeNode::new(0); root.borrow_mut() 此在相同資料 量下，鏈結串列比陣列佔用更多的記憶體空間。 use std::rc::Rc; use std::cell::RefCell; /* 鏈結串列節點類別 */ #[derive(Debug)] struct ListNode { val: i32, // 節點值 next: Option<Rc>>, // 指向下一節點的指標 } 4

It contains: Slide Duration Box |10 minutes| |Rc|5 minutes| |特徵物件|10 minutes| |練習：二元樹|30 minutes| 20.1 Box Box 是具有所有權的指向堆積上的資料的指標： fn main() { - - - - - ' '- - - - - - - - - - - - - -' 20.2 Rc Rc 是參考計數的共用指標。如要在多個位置參考相同的資料，可以使用這個指標： use std::rc::Rc; fn main() { let a = Rc::new(10); let b = Rc::clone(&a); println!("a: {a}"); println!("b: {b}");

build alpha- numeric annotations. For example, v"0.2.1-rc1+win64" is broken into major version 0, minor version 2, patch version 1, pre-release rc1 and build win64. When entering a version literal, everything above example the code would only run with stable 0.2 versions, and exclude such versions as v"0.3.0-rc1". In order to also allow for unstable (i.e. pre-release) 0.2 versions, the lower bound check should versions, e.g. VERSION > v"0.2-rc1+" can be used to mean any version above 0.2-rc1 and any of its builds: it will return false for version v"0.2-rc1+win64" and true for v"0.2-rc2". It is good practice to
