Hardware Labels​
When a node is registered, the data is stored in the inventory with default labels and values relative to the node hardware.
This data is used for easy identification and selection via a MachineSelector.
The following labels are set up automatically:
| Label | Description |
|---|---|
| elemental.cattle.io/TotalMemory | The total RAM memory in the node, expressed in bytes |
| elemental.cattle.io/CpuTotalCores | Total CPU cores |
| elemental.cattle.io/CpuTotalThreads | Total CPU threads |
| elemental.cattle.io/CpuVendor | CPU vendor |
| elemental.cattle.io/CpuModel | CPU model |
| elemental.cattle.io/GpuModel | GPU model (Only available if the node has an identifiable GPU) |
| elemental.cattle.io/GpuVendor | GPU vendor (Only available if the node has an identifiable GPU) |
| elemental.cattle.io/NetNumberInterfaces | Number of network interfaces in the system |
| elemental.cattle.io/NetIfaceX-Name | Network interface name |
| elemental.cattle.io/NetIfaceX-Virtual | Whether the Network Interface is a virtual one |
| elemental.cattle.io/BlockTotal | Number of block devices in the system (includes DVD and USB drives) |
| elemental.cattle.io/BlockDeviceX-Name | Device name of the block device (i.e. sda, sr0, vda, etc...) |
| elemental.cattle.io/BlockDeviceX-Removable | Whether this block device is removable (i.e. DVD) |
| elemental.cattle.io/BlockDeviceX-Size | Total space in this block device, expressed in bytes |
| elemental.cattle.io/BlockDeviceX-DriveType | Drive type of this block device, see table below |
| elemental.cattle.io/BlockDeviceX-ControllerType | Controller type for this block device connection, see table below |
info
On both BlockDeviceX and NetIfaceX the X indicates a number, as there could be more than one device. Numbers are just for enumeration purposes and have no relation with the underlying hardware.
Block device drive types​
| Type | Description |
