Sync from Host to Virtual

Declare which host resources you want to sync to the virtual cluster.

vCluster can sync certain resources purely from host to make them available inside the vCluster. This is useful if you only want to view certain resources in read-only mode, but not want the users inside the vCluster to change them.

A good example would be nodes, which are nice to view inside the vCluster and can be also used to enabled certain features such as scheduling inside the vCluster, but you wouldn't want your vCluster to change the node itself. Another benefit of purely syncing from host is that vCluster itself will only require read-only RBAC permissions.

vCluster also allows to sync custom resources via the custom resource definitions syncer

Config reference

fromHost required object pro

Configure what resources vCluster should sync from the host cluster to the virtual cluster.

nodes required object pro

Nodes defines if nodes should get synced from the host cluster to the virtual cluster, but not back.

enabled required boolean false pro

Enabled specifies if syncing real nodes should be enabled. If this is disabled, vCluster will create fake nodes instead.

syncBackChanges required boolean false pro

SyncBackChanges enables syncing labels and taints from the virtual cluster to the host cluster. If this is enabled someone within the virtual cluster will be able to change the labels and taints of the host cluster node.

clearImageStatus required boolean false pro

ClearImageStatus will erase the image status when syncing a node. This allows to hide images that are pulled by the node.

selector required object pro

Selector can be used to define more granular what nodes should get synced from the host cluster to the virtual cluster.

all required boolean false pro

All specifies if all nodes should get synced by vCluster from the host to the virtual cluster or only the ones where pods are assigned to.

labels required object {} pro

Labels are the node labels used to sync nodes from host cluster to virtual cluster. This will also set the node selector when syncing a pod from virtual cluster to host cluster to the same value.

events required object pro

Events defines if events should get synced from the host cluster to the virtual cluster, but not back.

enabled required boolean true pro

Enabled defines if this option should be enabled.

ingressClasses required object pro

IngressClasses defines if ingress classes should get synced from the host cluster to the virtual cluster, but not back.

enabled required boolean false pro

Enabled defines if this option should be enabled.

runtimeClasses required object pro

RuntimeClasses defines if runtime classes should get synced from the host cluster to the virtual cluster, but not back.

enabled required boolean false pro

Enabled defines if this option should be enabled.

priorityClasses required object pro

PriorityClasses defines if priority classes classes should get synced from the host cluster to the virtual cluster, but not back.

enabled required boolean false pro

Enabled defines if this option should be enabled.

storageClasses required object pro

StorageClasses defines if storage classes should get synced from the host cluster to the virtual cluster, but not back. If auto, is automatically enabled when the virtual scheduler is enabled.

enabled required string|boolean auto pro

Enabled defines if this option should be enabled.

csiNodes required object pro

CSINodes defines if csi nodes should get synced from the host cluster to the virtual cluster, but not back. If auto, is automatically enabled when the virtual scheduler is enabled.

enabled required string|boolean auto pro

Enabled defines if this option should be enabled.

csiDrivers required object pro

CSIDrivers defines if csi drivers should get synced from the host cluster to the virtual cluster, but not back. If auto, is automatically enabled when the virtual scheduler is enabled.

enabled required string|boolean auto pro

Enabled defines if this option should be enabled.

csiStorageCapacities required object pro

CSIStorageCapacities defines if csi storage capacities should get synced from the host cluster to the virtual cluster, but not back. If auto, is automatically enabled when the virtual scheduler is enabled.

enabled required string|boolean auto pro

Enabled defines if this option should be enabled.

customResourceDefinitions required {key: object} pro

CustomResourceDefinitions defines what custom resource definitions should get synced read-only to the virtual cluster from the host cluster.

enabled required boolean pro

Enabled defines if this option should be enabled.
