[id="installation-vsphere-installer-infra-minimum-requirements_{context}"] == Minimum required vCenter account privileges After you create a custom role and assign privileges to the role, you can create permissions by selecting specific vSphere objects. You can then assign the custom role to a user or group for each object. Before you create permissions or request for the creation of permissions for a vSphere object, decide what minimum permissions apply to the vSphere object. By doing this task, you can ensure a basic interaction exists between a vSphere object and {product-title} architecture. [IMPORTANT] ==== If you create a custom role and you do not assign privileges to it, the vSphere Server by default assigns a `Read Only` role to the custom role. Note that for the cloud provider API, the custom role only needs to inherit the privileges of the `Read Only` role. ==== Consider creating a custom role when an account with global administrative privileges does not meet your needs. [IMPORTANT] ==== Red{nbsp}Hat does not support configuring an account without including the required privileges. Installing an {product-title} cluster in a vCenter is tested against a full list of privileges as described in the "Required vCenter account privileges" section. By adhering to the full list of privileges, you can reduce the possibility of unexpected behaviors that might occur when creating a custom role with a restricted set of privileges. ==== The following tables specify how the required vCenter account privileges provided earlier in this document are relevant to different aspects of {product-title} architecture. ifndef::upi[] [id="installation-vsphere-minimum-permissions-ipi_{context}"] .Minimum permissions on installer-provisioned infrastructure [%collapsible] ==== [cols="4a,4a,3a",options="header"] |=== |vSphere object for role |When required |Required privileges |vSphere vCenter |Always | [%hardbreaks] `Cns.Searchable` `InventoryService.Tagging.AttachTag` `InventoryService.Tagging.CreateCategory` `InventoryService.Tagging.CreateTag` `InventoryService.Tagging.DeleteCategory` `InventoryService.Tagging.DeleteTag` `InventoryService.Tagging.EditCategory` `InventoryService.Tagging.EditTag` `Sessions.ValidateSession` `StorageProfile.Update` `StorageProfile.View` |vSphere vCenter Cluster |If you intend to create VMs in the cluster root | [%hardbreaks] `Host.Config.Storage` `Resource.AssignVMToPool` `VApp.AssignResourcePool` `VApp.Import` `VirtualMachine.Config.AddNewDisk` |vSphere vCenter Resource Pool |If you included an existing resource pool in the `install-config.yaml` file | [%hardbreaks] `Host.Config.Storage` `Resource.AssignVMToPool` `VApp.AssignResourcePool` `VApp.Import`minimum` |vSphere Datastore |If you referenced a datastore in the `install-config.yaml` file | [%hardbreaks] `Datastore.Browse` `Datastore.FileManagement` `InventoryService.Tagging.ObjectAttachable` |vSphere Port Group |Always | [%hardbreaks] `Network.Assign` |Virtual Machine Folder |Always | [%hardbreaks] `InventoryService.Tagging.ObjectAttachable` `Resource.AssignVMToPool` `VApp.Import` `VirtualMachine.Config.AddExistingDisk` `VirtualMachine.Config.AddNewDisk` `VirtualMachine.Config.AddRemoveDevice` `VirtualMachine.Config.AdvancedConfig` `VirtualMachine.Config.Annotation` `VirtualMachine.Config.CPUCount` `VirtualMachine.Config.DiskExtend` `VirtualMachine.Config.DiskLease` `VirtualMachine.Config.EditDevice` `VirtualMachine.Config.Memory` `VirtualMachine.Config.RemoveDisk` `VirtualMachine.Config.Rename` `VirtualMachine.Config.ResetGuestInfo` `VirtualMachine.Config.Resource` `VirtualMachine.Config.Settings` `VirtualMachine.Config.UpgradeVirtualHardware` `VirtualMachine.Interact.GuestControl` `VirtualMachine.Interact.PowerOff` `VirtualMachine.Interact.PowerOn` `VirtualMachine.Interact.Reset` `VirtualMachine.Inventory.Create` `VirtualMachine.Inventory.CreateFromExisting` `VirtualMachine.Inventory.Delete` `VirtualMachine.Provisioning.Clone` `VirtualMachine.Provisioning.MarkAsTemplate` `VirtualMachine.Provisioning.DeployTemplate` |vSphere vCenter data center |If the virtual machine folder does not already exist, the installation program creates the virtual machine folder.
