  9. Returns a valid value for the "source" parameter of a "file.managed"
  10. state function. This makes easier the usage of the Template Override and
  11. Files Switch (TOFS) pattern.
  12. Params:
  13. * source_files: ordered list of files to look for
  14. * lookup: key under "<tplroot>:tofs:source_files" to prepend to the
  15. list of source files
  16. * default_files_switch: if there's no config (e.g. pillar)
  17. "<tplroot>:tofs:files_switch" this is the ordered list of grains to
  18. use as selector switch of the directories under
  19. "<path_prefix>/files"
  20. * indent_width: indentation of the result value to conform to YAML
  21. * use_subpath: defaults to `False` but if set, lookup the source file
  22. recursively from the current state directory up to `tplroot`
  23. Example (based on a `tplroot` of `xxx`):
  24. If we have a state:
  25. Deploy configuration:
  26. file.managed:
  27. - name: /etc/yyy/zzz.conf
  28. - source: {{ files_switch(
  29. ["/etc/yyy/zzz.conf", "/etc/yyy/zzz.conf.jinja"],
  30. lookup="Deploy configuration",
  31. ) }}
  32. - template: jinja
  33. In a minion with id=theminion and os_family=RedHat, it's going to be
  34. rendered as:
  35. Deploy configuration:
  36. file.managed:
  37. - name: /etc/yyy/zzz.conf
  38. - source:
  39. - salt://xxx/files/theminion/etc/yyy/zzz.conf
  40. - salt://xxx/files/theminion/etc/yyy/zzz.conf.jinja
  41. - salt://xxx/files/RedHat/etc/yyy/zzz.conf
  42. - salt://xxx/files/RedHat/etc/yyy/zzz.conf.jinja
  43. - salt://xxx/files/default/etc/yyy/zzz.conf
  44. - salt://xxx/files/default/etc/yyy/zzz.conf.jinja
