kubernetes - Deployment.apps 无效 : spec. template.spec.containers[0].volumeMounts[1].name:未找到: "data"

Question

我正在部署一个名为 soa-illidan-hub-service 的应用程序，在 kubernetes 版本 v1.16.0 中有一个持久卷。当我应用 yaml 时，它给我这个错误:

Deployment.apps "soa-illidan-hub-service" is invalid: spec.template.spec.containers[0].volumeMounts[1].name: Not found: "data"

这是我的 yaml 文件:

          requests:
            storage: 10Gi
        volumeMode: Filesystem
  progressDeadlineSeconds: 600

为了添加 PV，我添加了 volumeClaimTemplates 配置:

 volumeClaimTemplates:
        - metadata:
            name: data
            creationTimestamp: null
          spec:
            accessModes:
              - ReadWriteOnce
            resources:
              requests:
                storage: 10Gi
            volumeMode: Filesystem

我在我的 pod 中使用这个卷是这样的:

volumeMounts:
   - name: data
      mountPath: /var/export/data

我是不是遗漏了什么？我应该怎么做才能解决这个问题？

Answer 1

我认为您的部署定义是问题所在。

查看 k8s 文档，我发现 this example :

kind: Pod
metadata:
  name: test-pd
spec:
  containers:
  - image: k8s.gcr.io/test-webserver
    name: test-container
    volumeMounts:
    - mountPath: /cache
      name: cache-volume
  volumes:
  - name: cache-volume
    emptyDir: {}

基本上，您需要在容器下定义 volumeMounts，并将 volumeMount 引用到 volumes 部分下的有效卷。

只是强调一下，名称应该匹配，否则，它也会失败。
