Watch multiple files in a directory

[Arthur Lutz]

Hi list,

Does anyone know a way of watching multiple files in a directory in the
"watch" directive ?

For example : if the highstate adds or modifies a file in
/etc/apt/sources.d/ do "apt-get update"

I would need this with cmd.run (since I'd like to apply it to
backuppc/munin/shinken/monit)

We've tried some stuff with extend and watching multiple explicitly
defined files but it doesn't seem to work the way we expect it.

If this is not possible I'd be happy to add a ticket. Thanks in advance.

Arthur

There is only one way - list all files which you want to watch:

watch:
- file: /etc/apt/sources.d/a
- file: /etc/apt/sources.d/b
- file: /etc/apt/sources.d/c

It's because requisite (watch, require) doesn't look
at file or directory (etc) literally, it looks at state
which has id occasionally looks like file name you want
to watch.

If /etc/apt/sources.d is a key itself (i.e., as a file.directory), I believe you can simply watch it:

watch:

  - file: /etc/apt/sources.d

You could also use watch_in to do it the other way around.

/etc/apt/sources.d:

  - file.directory:

    <whatever else you have here>

  - watch_in:

    - your-apt-update-cmd

If those aren't options, I'd try a jinja loop to add several individual file watch directives, as Denis has shown.  I'd consider actually listing out all of the files in the directory by hand as a last resort, which wouldn't help in the situation where the list of files changes (rather than simply their contents).

From my experiments, "watch_in" works fine with file.recurse:

asterisk:
pkg:
- installed
service:
- running
file.recurse:
- name: /etc/asterisk
- require:
- pkg: asterisk
- watch_in:
- service: asterisk
- source: salt://etc/asterisk
- user: asterisk
- group: asterisk
