PersistentVolumeClaim unknown in kubernetes

Question

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

错误是：

验证数据时出错： ValidationError(Pod.spec.containers[1](： io.k8s.api.core.v1.Container中的未知字段"persistentVolumeClaim";

我不明白为什么我会收到错误，因为我在我的 pd.yaml 配置:(中写了claimName：在持久卷声明下

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:

resources:

Answer 1

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。正如您在此处从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

此级别/API 对象不支持persistentVolumeClaims，这就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

Answer 2

> 根据 kubernetes 文档，persistentVolumeClaim是.spec.volume级别的一部分，而不是pod对象.spec.container级别。

正确的pod.yaml是：

apiVersion: v1
kind: Pod
metadata:
name: karafpod
spec:
volumes:
- name: efgkaraf-conf-storage
persistentVolumeClaim:
claimName: efgkaraf-conf-claim
containers:
- name: karaf
image: docker-all.attanea.net/library/efgkaraf:ids-1.1.0
volumeMounts:
- name: efgkaraf-conf-storage
mountPath: /apps/karaf/etc
