kubernetes - PersistentVolumeClaim 在 kubernetes 中未知

Question

我尝试部署一个容器，但不幸的是，当我尝试执行 kubectl apply -f *.yaml

时出现错误

错误是:

error validating data: ValidationError(Pod.spec.containers[1]): unknown field "persistentVolumeClaim" in io.k8s.api.core.v1.Container;

我不明白为什么我会收到错误，因为我在我的 pd.yaml 配置中的 persistentVolumeClaim: 下写了 claimName: :(

Pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: karafpod
spec:
  containers:
  - name: karaf
    image: xxx/karaf:ids-1.1.0
    volumeMounts:
    - name: karaf-conf-storage
      mountPath: /apps/karaf/etc
  - name: karaf-conf-storage
    persistentVolumeClaim:
      claimName: karaf-conf-claim

PersistentVolumeClaimKaraf.yml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: karaf-conf-claim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Mi

部署.yaml

 apiVersion: extensions/v1beta1
 kind: Deployment
 metadata:
   name: karaf
   namespace: poc 
 spec:
   replicas: 1
   template:
     metadata:
       labels:
         app: karaf
     spec:
       containers:
       - name: karaf
         image: "xxx/karaf:ids-1.1.0"
         imagePullPolicy: Always
         ports:
         - containerPort: 6443
         - containerPort: 6100
         - containerPort: 6101
         resources: 
         volumeMounts:
         - mountPath: /apps/karaf/etc
           name: karaf-conf
       volumes:
       - name: karaf-conf
         persistentVolumeClaim:
           claimName: karaf-conf

您看到该错误的原因是您在 pod 规范的容器规范下指定了 persistentVolumeClaim。正如您从此处自动生成的文档中看到的那样:https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.10/#container-v1-core

persistentVolumeClaims 在此级别/API 对象上不受支持，这是导致您看到的错误的原因。

您应该修改 pod.yml 以将其指定为卷。

例如:

apiVersion: v1
kind: Pod
metadata:
  name: karafpod
spec:
  containers:
    - name: karaf
      image: xxx/karaf:ids-1.1.0
      volumeMounts:
      - name: karaf-conf-storage
        mountPath: /apps/karaf/etc
  volumes:
    - name: karaf-conf-storage
      persistentVolumeClaim:
        claimName: karaf-conf-claim
