It takes 2 input YAML files and an output file as arguments. One being +the dictionary (called the base file), which is used to look up values in; the +other file is the template, where the substitution will take place. Templater +will write the result to an output file, specified as the 3rd argument. + + +======== SYNTAX OF TEMPLATE FILES ======== + +A template file can contain any valid YAML data and template variables, whose +syntax is described below: + +1. Single value references + + %{title} + + %{environment/net_segment_type} + + Either a root element, or a path can be specified. + +2. YAML sections + + %{nodes} + + %{network/networking_parameters} + + Either a root element, or a path can be specified. + +3. Interface lookup for network + + %{interface(storage)} + + Specify a network type as argument to interface(). + +4. Interface lookup for network and role + + %{interface(public,compute)} + + Specify a network type and a role as arguments to interface(). + +5. File inclusion + + %{include(templates/interfaces.yaml)} + + Filename with absolute or relative path. + + +======== EXAMPLES ======== + +Base YAML file (excerpt): + +title: Deployment Environment Adapter (DEA) +version: 1.1 +created: Wed Mar 30 08:16:04 2016 +environment: + name: vCity + net_segment_type: tun +wanted_release: Liberty on Ubuntu 14.04 +nodes: +- id: 1 + interfaces: interfaces_1 + role: ceph-osd,compute + transformations: transformations_1 +- id: 2 + interfaces: interfaces_1 + role: ceph-osd,compute + transformations: transformations_1 +- id: 3 + interfaces: interfaces_1 + role: ceph-osd,compute + transformations: transformations_1 +- id: 4 + interfaces: interfaces_2 + role: controller,mongo + transformations: transformations_2 +- id: 5 + interfaces: interfaces_2 + role: controller,mongo + transformations: transformations_2 +- id: 6 + interfaces: interfaces_2 + role: controller,mongo + transformations: transformations_2 +interfaces_1: + ens3: + -
