-------------------------------------------------------------------------------- /hands-on/advanced/affinity/README.md: -------------------------------------------------------------------------------- 1 | # Kubernetes 節點親和性練習 2 | 3 | 根據以下範例，了解如何使用 Kubernetes 的節點親和性功能將 Pod 定位在特定節點上。 4 | 5 | ## 練習步驟 6 | 7 | 1. 為任意節點添加自定義標籤，例如 `user-=user-` (請將 `` 替換為您自己的 ID): 8 | 9 | ``` 10 | $ kubectl label node user-0=user-0 11 | ``` 12 | 13 | 2. 修改以下範例 YAML 文件，以創建使用節點親和性的 Deployment 14 | 15 | * 使用 `requiredDuringSchedulingIgnoredDuringExecution` 16 | 17 | ```yaml 18 | apiVersion: apps/v1 19 | kind: Deployment 20 | metadata: 21 | name: affinity-prefer-nginx 22 | spec: 23 | replicas: 1 24 | selector: 25 | matchLabels: 26 | app: nginx 27 | template: 28 | metadata: 29 | labels: 30 | app: nginx 31 | spec: 32 | # 在此添加 nodeAffinity 33 | containers: 34 | - image: nginx 35 | name: nginx 36 | resources: {} 37 | ``` 38 | 39 | 3. 創建成功後，確認 Pod 是否在指定節點上運行 40 | 41 | ``` 42 | $ kubectl get pod -o wide 43 | ``` 44 | 45 | ## 使用 Deployment 模擬 DaemonSet 的效果 46 | 47 | 1. 使用 `kubectl describe node` 查看要用作 `topologyKey` 的標籤，並利用 `Pod Anti-affinity` 確保每個 worker 節點都有一個 Pod。 48 | 49 | * `topologyKey` 可以使用 `kubernetes.io/hostname` 50 | 51 | 2. 參考以下範例 YAML 文件創建 2 個 Deployment，分別練習: 52 | 53 | * requiredDuringSchedulingIgnoredDuringExecution 54 | * preferredDuringSchedulingIgnoredDuringExecution 55 | 56 | ``` 57 | apiVersion: apps/v1 58 | kind: Deployment 59 | metadata: 60 | name: deployment-as-daemonset 61 | spec: 62 | replicas: <節點數量 + 1> 63 | selector: 64 | matchLabels: 65 | app:

resources: {} 76 | ``` 77 | 78 | 3. 確認 `required` 與 `preferred` 兩種做法的差異： 79 | 80 | ``` 81 | $ kubectl get pod -o wide 82 | ``` 83 | 84 | 通過以上練習，您將了解如何在 Kubernetes 中使用節點親和性和 Pod 反親和性功能， 85 |
