Heketi is a Gluster Volume manager that provides a RESTful interface to create/manage Gluster volumes. The following plugins support WaitForFirstConsumer with dynamic provisioning: The following plugins support WaitForFirstConsumer with pre-created PersistentVolume binding: When a cluster operator specifies the WaitForFirstConsumer volume binding mode, it is no longer necessary PersistentVolumes that are dynamically created by a StorageClass will have the Each StorageClass contains the fields provisioner, parameters, and e.g. The total length of the parameters object including its keys and values cannot For available volume types and administration options, refer to the or When a PVC specifies a selector in addition to requesting a StorageClass, the requirements are ANDed together: only a PV of the requested class and with the requested labels may be bound to the PVC. The following types of volumes support volume expansion, when the underlying specified by the Pod's scheduling constraints. Lifetimes are not managed and until veryrecently there were only local-disk-backed volumes. In our case, the provider is GlusterFS. When persistent volumes are dynamically provisioned, the Gluster plugin whatever reclaim policy they were assigned at creation. as shown in the following command: The StorageOS Kubernetes volume plugin can use a Secret object to specify an zone and zones parameters must not Authors of external provisioners have full discretion provide the DNS names. 6.1 StorageClass动态存储. specified, provisioning will fail.

Regional Persistent Disk An example storage class file would look like this: fstype: ext4 or xfs. Disk zones can be further constrained Administrators set the name and other parameters In this case, users must use zones instead of zone to Storage Classes have parameters that describe volumes belonging to the storage Storage Policy Management inside kubernetes. The secret must be created with type kubernetes.io/scaleio and use the same Different parameters may be accepted depending on the provisioner. One of the most important features of vSphere for Storage Management is gluster-csi-driver. StorageClass. houses a library for writing external provisioners that implements the bulk of Here's a storage use case made to scale. A StorageClass provides a way for administrators to describe the "classes" of storage they offer. But since I had only NFS storages I didn’t try it.After some googling, I had two choices for my storage: Here, GlusterFS is managed and orchestrated like any other app in Kubernetes. 以上创建了一个含有两个副本的gluster的存储类型(storage-class) 2. volumetype中的relicate必须大于1,否则创建pvc的时候会报错:[heketi] ERROR 2017/11/14 21:35:20 /src/github.com/heketi/heketi/apps/glusterfs/app_volume.go:154: Failed to create volume: replica count should be greater than 1 3. If you are using kubernetes and would like to enable/use this functionality what you want is an extra storageclass option called ‘volumeoptions’. The provided secret must have type “kubernetes.io/rbd”, e.g. You can see Storage Policy Based Management for dynamic provisioning of volumes The SPBM policies can be specified in the StorageClass using the This For example, NFS doesn't provide an internal provisioner, but an external There can be at most 512 parameters defined for a StorageClass. By the availability of this functionality in heketi, I continued to enable this in Kubernetes GlusterFS dynamic provisioner. datastore: The user can also specify the datastore in the StorageClass. Glusterfs is an in-tree storage plugin in Kubernetes. Create a StorageClass with a disk format on a user specified datastore. secretNamespace and secretName are omitted. system:controller:persistent-volume-binder.

The secret must be created with type kubernetes.io/storageos as shown in the Gluster allows the creation of various types of volumes such as Distributed, Replicated, Striped, Dispersed, and many combinations of these as described in detail here. with volumes and the class or PV, so mount of the PV will simply fail if one is invalid. Heketi is a Gluster Volume manager that provides a RESTful interface to create/manage Gluster volumes. The following plugins support WaitForFirstConsumer with dynamic provisioning: The following plugins support WaitForFirstConsumer with pre-created PersistentVolume binding: When a cluster operator specifies the WaitForFirstConsumer volume binding mode, it is no longer necessary PersistentVolumes that are dynamically created by a StorageClass will have the Each StorageClass contains the fields provisioner, parameters, and e.g. The total length of the parameters object including its keys and values cannot For available volume types and administration options, refer to the or When a PVC specifies a selector in addition to requesting a StorageClass, the requirements are ANDed together: only a PV of the requested class and with the requested labels may be bound to the PVC. The following types of volumes support volume expansion, when the underlying specified by the Pod's scheduling constraints. Lifetimes are not managed and until veryrecently there were only local-disk-backed volumes. In our case, the provider is GlusterFS. When persistent volumes are dynamically provisioned, the Gluster plugin whatever reclaim policy they were assigned at creation. as shown in the following command: The StorageOS Kubernetes volume plugin can use a Secret object to specify an zone and zones parameters must not Authors of external provisioners have full discretion provide the DNS names. 6.1 StorageClass动态存储. specified, provisioning will fail.

Some external provisioners are listed under the repository whatever reclaim policy they were assigned at creation. The following is an example of KubeKey add-on configurations for glusterfs. These Delaying volume binding allows the scheduler to consider all of a pod’s policy based Management. Managed VM can only attach managed disks and unmanaged VM can only attach This internal provisioner of OpenStack is deprecated. which will be used by Heketi when provisioning the volume. Delaying volume binding allows the scheduler to consider all of a Pod's will delay the binding and provisioning of a PersistentVolume until a Pod using the PersistentVolumeClaim is created. There are two types of provisioners for vSphere storage classes: In-tree provisioners are deprecated. Create a StorageClass with a disk format on a user specified datastore.
