Question

我有一个 k8s 部署，需要大型 ssd 本地存储来实现高性能文件读/写。连接到集群的所有节点都有大 ssd 卷 (350GB)。这是

apiVersion: apps/v1
kind: Deployment
metadata:
  annotations: {}
  labels:
    name: main
  name: main
  namespace: fileaccessor
spec:
  minReadySeconds: 30
  replicas: 1
  revisionHistoryLimit: 10
  selector:
    matchLabels:
      name: main
  strategy:
    rollingUpdate:
      maxSurge: 25%
      maxUnavailable: 25%

  template:
    metadata:
      annotations: {}
      labels:

          command:
            - /app/fileaccessor
          env: []
          image: ----:fileaccessor
          imagePullPolicy: IfNotPresent
          name: main
          ports: []
          resources:
            requests:
              cpu: "2"
          stdin: false
          tty: false
          volumeMounts: []
      imagePullSecrets: []
      initContainers: []

Pod 启动后，我登录并检查磁盘。它只有 20GB 的磁盘大小。

我在 Internet 上进行了一些搜索，但没有找到任何不指定卷来增加 pod 磁盘大小的方法。我是否必须指定本地卷才能获得更大的尺寸？同样用于部署，是否可以使用卷挂载？似乎大多数示例都是针对 Pod 的。
