{#-
|

|
|
Returns a valid value for the "source" parameter of a "file.managed"
|
||
|
|
state function. This makes easier the usage of the Template Override and
|
||
|
|
Files Switch (TOFS) pattern.
|
||
|
|
|
||
|
|
Params:
|
||
|
|
* source_files: ordered list of files to look for
|
||
|
|
* lookup: key under '<tplroot>:tofs:source_files' to override
|
||
|
|
list of source files
|
||
|
|
* default_files_switch: if there's no config (e.g. pillar)
|
||
|
|
'<tplroot>:tofs:files_switch' this is the ordered list of grains to
|
||
|
|
use as selector switch of the directories under
|
||
|
|
"<path_prefix>/files"
|
||
|
|
* indent_witdh: indentation of the result value to conform to YAML
|
||
|
|
* v1_path_prefix: (deprecated) only used for injecting a path prefix into
|
||
|
|
the source, to support older TOFS configs
|
||
|
|
|
||
|
|
Example (based on a `tplroot` of `xxx`):
|
||
|
|
|
||
|
|
If we have a state:

|
|
|
||
|
|
Deploy configuration:
|
||
|
|
file.managed:
|
||
|

- name: /etc/yyy/zzz.conf

- source: {{ files_switch(['/etc/yyy/zzz.conf', '/etc/yyy/zzz.conf.jinja'],
|

lookup='Deploy configuration'
|

) }}
|

- template: jinja
