Doing this on a mobile so bear with me.

If your file is under a file.managed state just call

{{ salt['grains.get']('fqdn') }}

where appropriate

Hello,

grains for this purpose will be better.

Let's have look like on hostname and there are 2 way how to specify value just in file or over context in state:

/path/to/file:

  file.managed:

    - replace: True # To replace everytime

    - source: salt://path/to/file 

    - template: jinja # For resolve the value in the file

    - context: 

      host: {{ grains['host'] }}

The file where source point will look like this:

-- place somewhere in of file --

{{ host }}

-- end of file --

If you want specify value just in the file, remove context definition and in the file edit to:

-- place somewhere of file --

{{ grains['host'] }}

-- end of file --

If you want do this with  grains also provide by default FQDN in grains['fqdn']

Full list what minions return you will get by command from master:

salt 'target' grains.ls

Have a good day!
