The module is automatically enabled for all cloud clusters deployed in vSphere.
If the cluster control plane is hosted on a virtual machines or bare-metal servers, the cloud provider uses the settings from the cloud-provider-vsphere
module in the Deckhouse configuration (see below). Otherwise, if the cluster control plane is hosted in a cloud, the cloud provider uses the VsphereClusterConfiguration structure for configuration.
You can configure the number and parameters of ordering machines in the cloud via the NodeGroup
custom resource of the node-manager
module. Also, in this custom resource, you can specify the instance class’s name for the above group of nodes (the cloudInstances.ClassReference
parameter of NodeGroup). In the case of the vSphere cloud provider, the instance class is the VsphereInstanceClass
custom resource that stores specific parameters of the machines.
Storage
The module automatically creates a StorageClass for each Datastore and DatastoreCluster in the zone (or zones).
Also, it can set the name of StorageClass that will be used in the cluster by default (the default parameter), and filter out the unnecessary StorageClasses (the exclude parameter).
CSI
By default, the storage subsystem uses CNS volumes with the ability of online-resize. FCD volumes are also supported, but only in the legacy or migration modes. You can set this via the compatibilityFlag parameter.
Important information concerning the increase of the PVC size
Due to the nature f volume-resizer, CSI, and vSphere API, you have to do the following after increasing the PVC size:
- On the node where the Pod is located, run the
kubectl cordon <node_name>
command. - Delete the Pod.
- Make sure that the resize was successful. The PVC object must not have the
Resizing
condition.The
FileSystemResizePending
state is OK. - On the node where the Pod is located, run the
kubectl uncordon <node_name>
command.
