TEMPLATE_RECREATE="false" #Fore recreate template ?
#Note: If you want only update hook script and Template_Ignition file, you can keep it as false, these files are always overwritten
TEMPLATE_POOL="domain.lan"# domain name written in cloudinit config
TEMPLATE_VMSTORAGE="local" #target storage for Template VM
SNIPPET_STORAGE="local" #target storage for Snippets files
VMDISK_OPTIONS=",discard=on"

# flatcar image version
VERSION=latest # default: latest, possible values: <version_num>, latest, current
