Kubernetes错误“无法附加或装入卷”

Question

我使用nginx作为负载平衡器(如这里 )部署了bitnami/wordpress头盔。一切正常工作，但问题是，当一些豆荚是手动或自动创建自动标度。其中一些(并非所有)都具有"ContainerCreating“状态，日志如下所示：

  Normal   Scheduled    33m                  default-scheduler  Successfully assigned default/wordpress-69c8f65d96-wnkfv to main-node-d29388
  Warning  FailedMount  4m28s (x6 over 29m)  kubelet            Unable to attach or mount volumes: unmounted volumes=[wordpress-data], unattached volumes=[default-token-s4gdj wordpress-data]: timed out waiting for the condition
  Warning  FailedMount  0s (x9 over 31m)     kubelet            Unable to attach or mount volumes: unmounted volumes=[wordpress-data], unattached volumes=[wordpress-data default-token-s4gdj]: timed out waiting for the condition

我部署了bitnami/wordpress，然后使用以下设置进行升级：

helm install wordpress bitnami/wordpress --set service.type=ClusterIP --set ingress.enabled=true --set ingress.certManager=true --set ingress.annotations."kubernetes\.io/ingress\.class"=nginx --set ingress.annotations."cert-manager\.io/cluster-issuer"=letsencrypt-prod --set ingress.hostname=DOMAIN.com --set ingress.extraTls[0].hosts[0]=DOMAIN.com --set ingress.extraTls[0].secretName=wordpress.local-tls --set wordpressPassword=PASSWORD --set autoscaling.enabled=true --set autoscaling.minReplicas=1 autoscaling.maxReplicas=30

怎样才能避免新豆荚出现这个问题，并让它们开始呢？

用户@Juan是对的。我做了类似的方法，我用helm创建了其他POD，它创建了存储，我在wordpress部署中将它设置为persistance。这里描述的是：https://docs.bitnami.com/tutorials/deploy-applications-nfs-kubernetes/
