kubernetes - 如何创建基于架构部署的k8s部署文件

Question

我编写了如下部署文件，这给我带来了错误:未知字段“平台”。您知道要指定什么以便基于架构进行部署吗？

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80
        platform:
          architecture: amd64
          os: linux
      - name: nginx
        image: ppc64le/nginx:1.7.9
        ports:
        - containerPort: 80
        platform:
          architecture: ppc64le
          os: linux

Answer 1

您必须在部署规范中使用 nodeAffinity 定义。下面是我用来将任务固定到 amd64 或 arm 主机的示例:

  affinity:
    nodeAffinity:
      requiredDuringSchedulingIgnoredDuringExecution:
        nodeSelectorTerms:
        - matchExpressions:
          - key: beta.kubernetes.io/arch
            operator: In
            values:
            - amd64

您可以使用任意键和值。这是documented example
