RabbitMQ cluster-operator在Kubernetes中不起作用

Question

RabbitMQ集群运算符在kubernetes中不起作用。
我有一个由3个节点组成的kubernetes集群1.17.17。我和一个牧场主一起部署的。根据此说明，我安装了RabbitMQ cluster-operator:https://www.RabbitMQ.com/kubernetes/operator/quickstart-operator.html
kubectl apply-f“https://github.com/RabbitMQ/cluster-operator/releases/lates/download/cluster-operator.yml”
好！但是..我根据文档为实例创建了这个非常简单的配置：

apiVersion: rabbitmq.com/v1beta1
kind: RabbitmqCluster
metadata:
  name: rabbitmq
  namespace: test-rabbitmq

我有错误：在为pod“rabbitmq-server-0”运行“volumeBinding”筛选器插件时出错：pod已解除绑定立即PersistentVolumeClaims

之后，我检查了:
Kubectl get StorageClasses
，发现没有资源！我添加了以下StoreGleclass：

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

创建pv和PVC：

kind: PersistentVolume
apiVersion: v1
metadata:
  name: rabbitmq-data-sigma
  labels:
    type: local
  namespace: test-rabbitmq
  annotations:
    volume.alpha.kubernetes.io/storage-class: rabbitmq-data-sigma
spec:
  storageClassName: local-storage
  capacity:
    storage: 3Gi
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Recycle
  hostPath:
    path: "/opt/rabbitmq-data-sigma"
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: rabbitmq-data
  namespace: test-rabbitmq
spec:
  storageClassName: local-storage
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 3Gi

FailedBinding   no persistent volumes available for this claim and no storage class is set  

请帮助理解这个问题！

您可以配置动态卷配置，例如，如本文所述的动态NFS配置，也可以手动创建persistentvolume（不推荐使用这种方法）。

我确实建议您配置动态配置-这将允许您自动生成persistentvolumes。

正如我提到的，这不是推荐的方法，但当我们想要快速检查某些东西而不配置额外的组件时，它可能很有用。

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Recycle
  hostPath:
    path: /mnt/rabbitmq # data will be stored in the "/mnt/rabbitmq" directory on the worker node
    type: Directory

# kubectl get pv,pvc -A
NAME                   CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                                         STORAGECLASS   REASON   AGE
persistentvolume/pv    10Gi       RWO            Recycle          Bound    test-rabbitmq/persistence-rabbitmq-server-0                           11m


NAMESPACE       NAME                                                  STATUS   VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   AGE

# kubectl get pod -n test-rabbitmq
