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 prepend to the
* lookup: key under "<tplroot>:tofs:source_files" to prepend to the
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
"<tplroot>:tofs:files_switch" this is the ordered list of grains to
use as selector switch of the directories under
"<path_prefix>/files"
* indent_width: indentation of the result value to conform to YAML
* use_subpath: defaults to `False` but if set, lookup the source file
recursively from the current state directory up to `tplroot`
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'
) }}
- source: {{ files_switch(
["/etc/yyy/zzz.conf", "/etc/yyy/zzz.conf.jinja"],
lookup="Deploy configuration",
) }}
- template: jinja
In a minion with id=theminion and os_family=RedHat, it's going to be
rendered as:
Deploy configuration:
file.managed:
- name: /etc/yyy/zzz.conf
