#Reference

The YAML field reference. The visual editor exposes the most common fields under the same names (see each concept page); the tables below list every field, including the ones reachable only by editing the YAML.

#Template variables (boot commands)

Variable	Value
`{{ .HTTPIP }}`	IP of the build's HTTP file server (visible on the VM's first NIC subnet)
`{{ .HTTPPort }}`	Port of the HTTP server

#Top-level spec fields

Field	Type	Notes
`vms`	list	required, at least one
`files`	list	named files referenced by floppy/httpDirectory/file provisioners
`network`	object	optional VPC + subnet declarations
`httpDirectory`	object	files to serve over HTTP during boot
`buildOverrides`	object	settings active only during the build
`timeout`	duration string	default `30m`
`retries`	int	default `0`
`isoCacheTTL`	duration string	how long imported ISOs are cached, default `24h`

#Per-VM spec fields

Field	Type	Notes
`name`	string	required, DNS-label form
`source`	object	required, exactly one of url/containerDisk/buildRef/blank
`resources`	object	`cpu` (int), `memory` (Quantity); defaults `2` / `4Gi`
`disks`	list	first disk is boot disk; if omitted, a single 20Gi virtio disk is created
`communicator`	object	SSH config
`cloudInit`	object	required for cloud-image sources
`nics`	list	NIC assignments, omit to get a default NIC on the auto subnet
`bootCommand`	list of strings	VNC keystrokes typed before SSH attempts
`efiFirmware`	object	UEFI boot configuration
`provisioners`	list	ordered build steps
`isos`	list	ISO images to attach as cdrom
`floppy`	object	files to put on a virtual floppy

#Disk fields

Field	Type	Notes
`name`	string	required
`size`	Quantity	required (e.g. `"25Gi"`)
`bus`	string	`virtio` (default), `scsi`, `sata`

#NIC fields

Field	Type	Notes
`name`	string	required schema label; arbitrary DNS-label name, conventionally `nic{slot}`. Does not control the in-guest interface or PCI slot
`slot`	int	optional PCI slot, 1–9. Pins the NIC's PCI address so downstream builds keep per-adapter state on the same interface
`subnet`	string	required; references a subnet in `network`
`ip`	string	optional static IP; ignored when the assigned subnet is `unmanaged`
`mac`	string	optional static MAC
`model`	enum	`e1000` (default), `virtio`, `e1000e`, `rtl8139`, `pcnet`, `ne2k_pci`

#Subnet fields

Field	Type	Notes
`name`	string	required
`vpc`	string	optional; defaults to auto-VPC. Ignored when `unmanaged`
`cidr`	string	required for managed subnets, IPv4 CIDR. Ignored when `unmanaged`
`dhcp`	bool	default true. Ignored when `unmanaged`
`dns`	string	comma-separated DNS server IPs. Ignored when `unmanaged`
`unmanaged`	bool	default false. Plain Linux-bridge L2 segment with no IPAM/DHCP; see Networking for constraints

#VPC fields

Field	Type	Notes
`name`	string	required
`internet`	bool	enables NAT egress + public DNS, default false
