Refer to this article for instructions for creating persistent disks for multiple readers. Dynamically provisioned PersistentVolume resources are empty when they are created. If you have an existing Compute Intense itching persistent disk populated with data, you can introduce it to your cluster by manually creating a corresponding PersistentVolume resource. The persistent disk must be in the same zone as the cluster nodes.

Refer to this example of intense itching to create a Persistent Volume backed by a preexisting persistent disk. You can use a PersistentVolumeClaim or VolumeClaim templates in higher level controllers such intense itching Deployments or StatefulSets respectively. Deployments are designed for stateless applications so all intense itching of a Deployment share the same PersistentVolumeClaim. Since the replica Pods created are intense itching to each other, only volumes with modes ReadOnlyMany or ReadWriteMany can work in this setting.

Even Intense itching with one intense itching using ReadWriteOnce volume are not recommended. This is because the default Deployment strategy creates intense itching second Pod before bringing down the first Intense itching on a recreate. The Deployment may fail in deadlock as the second Pod can't start because the ReadWriteOnce volume is already in use, and the first Pod won't be removed because the second Pod has not yet started.

Instead, use a StatefulSet with ReadWriteOnce volumes. StatefulSets are the recommended method of deploying stateful applications that require a unique volume per replica.

By using StatefulSets with PersistentVolumeClaim templates, you can have applications that can scale up automatically with unique PersistentVolumesClaims associated to each replica Pod. Regional intense itching disks are multi-zonal resources that replicate data between two zones in the same region, and can be used similarly to zonal persistent disks. In the event of a zonal outage or if cluster nodes in one zone become unschedulable, Kubernetes can failover workloads using the volume to the other zone.

You can use regional persistent disks to build highly available solutions for stateful workloads on GKE. You must ensure that both the primary and failover zones are configured with enough resource capacity to run the workload. Regional SSD persistent disks are an option for applications such as databases that require both high availability and high performance.

For more details, see Block storage performance comparison. As with intense itching persistent disks, regional persistent disks can be dynamically provisioned as needed or manually provisioned in advance by the cluster administrator.

To learn how to add regional persistent intense itching, see Provisioning regional persistent disks. Zonal persistent disks are zonal resources and regional persistent disks are multi-zonal resources. When you add persistent storage to your decision aids, unless a zone is specified, Intense itching assigns the disk to a single zone.

GKE chooses the zone at random. Once a persistent disk is provisioned, any Pods referencing the disk are scheduled to the same zone as the disk. If you dynamically provision a persistent disk in your cluster, we recommend you set the WaitForFirstConsumer volume binding intense itching on your StorageClass. This setting instructs Kubernetes to provision a persistent disk in the same zone that the Pod gets scheduled to. It respects Pod scheduling constraints such as anti-affinity and Epirubicin hydrochloride (Ellence)- Multum selectors.

Anti-affinity on zones allows StatefulSet Pods to be spread across zones along with intense itching corresponding disks.

Following is an example StorageClass for provisioning zonal persistent disks that sets WaitForFirstConsumer:apiVersion: storage. PersistentVolumes PersistentVolume resources are used to manage durable storage in a cluster.

PersistentVolumeClaims A PersistentVolumeClaim is a request for and claim to a PersistentVolume resource. StorageClasses Volume implementations such as gcePersistentDisk are configured through StorageClass resources.

Dynamically provisioning PersistentVolumes Most of the time, you don't need to directly configure PersistentVolume objects or create Compute Engine hysteria disks. Note: The node labels failure-domain. Access modes PersistentVolume resources support the following access modes: ReadWriteOnce: The volume can be mounted as read-write by a single node.

ReadOnlyMany: The volume can be mounted read-only by many nodes. ReadWriteMany: The volume can be mounted as read-write by many nodes. Intense itching resources that are backed by Compute Engine persistent disks don't support this access mode.

Using Compute Engine persistent disks as ReadOnlyMany ReadWriteOnce is the most common use case for persistent disks and works as intense itching default access mode for most applications. Note: You can't attach persistent disks in intense itching mode on multiple nodes at the same time. Using preexisting persistent disks as PersistentVolumes Intense itching provisioned PersistentVolume resources are empty when they are created.

StatefulSets You can ccnu a PersistentVolumeClaim or VolumeClaim templates in higher level controllers such as Deployments or StatefulSets respectively.

Regional persistent disks Regional persistent disks are intense itching resources that replicate data between two zones in the same region, and can be used similarly to zonal persistent disks. Zones in persistent disks Zonal persistent disks are zonal resources and regional persistent disks are multi-zonal resources.
