Overview

Example

template := NewTemplate()

// Main
template.AddValue("cpu", 1)
template.AddValue("memory", "64")
template.AddValue("vcpu", "2")

// Disk
vector := template.NewVector("disk")
vector.AddValue("image_id", "119")
vector.AddValue("dev_prefix", "vd")

// NIC
vector = template.NewVector("nic")
vector.AddValue("network_id", "3")
vector.AddValue("model", "virtio")

fmt.Println(template)

Output:

CPU="1"
MEMORY="64"
VCPU="2"
DISK=[
    IMAGE_ID="119",
    DEV_PREFIX="vd" ]
NIC=[
    NETWORK_ID="3",
    MODEL="virtio" ]
