Puppet users - Nov 2010 - How to apply recursion to user, group and mode?

Hello, I would like to know it is possible to translate for example
the command
chmod -R 0777 /local.
As far as I know, I can write:
file { "/local":
     mode => 0777,
     recurse => true,

Hello, I would like to know it is possible to translate for example
the command
chmod -R 0777 /local.
As far as I know, I can write:
file { "/local":
     mode   => 0777,
     recurse => true,
     ensure  => directory;
}

but it does not apply the mode to all the /local subdirectories.
Is there a way to do that?

In addition, how is it possible to do
mkdir -P /local/dir1/dir2 .

if I write:

file { "/local/dir1/dir2":
     recurse => true,
     ensure  => directory;
}

it complains if /local/dir1 doesn''t exist.

I hope someone can help me.
Cheers,
Adriana

Well this isn''t an exact "translation" of the command.
Remember: in
puppet you don''t apply commands or run scripts. You define the state of
resources on your system and puppet will look that these resources are
in sync with your manifests. This is an important differentiation.

However in general your idea "should" work:

$ cd /tmp/
$ mkdir a a/b a/b/c
$ touch a/aa a/b/bb
$ cat foo.pp
file{''/tmp/a'':
  mode => 0777,
  recurse => true,
  ensure => directory,
}
$ puppet foo.pp
notice: /Stage[main]//File[/tmp/a]/mode: mode changed ''775'' to
''777''
notice: /File[/tmp/a/aa]/mode: mode changed ''664'' to
''777''
notice: /File[/tmp/a/b]/mode: mode changed ''775'' to
''777''
notice: /File[/tmp/a/b/bb]/mode: mode changed ''664'' to
''777''
notice: /File[/tmp/a/b/c]/mode: mode changed ''775'' to
''777''
$ ls -l /tmp/a/aa
-rwxrwxrwx. 1 foo foo 0 Nov 30 11:31 /tmp/a/aa

BUT: Is it possible that you manage these subdirectories somewhere else?
This would mean that you would have to manage the parameters of these
resources where you define them. File[''/local''] can''t
overwrite the
parameters of these resources, which would be a very bad idea.

You need to specify the whole directory tree you want to manage as with
puppet you describe for each directory the exact it should be in:

http://projects.puppetlabs.com/issues/86

You can also shorten this to:

file{[''/local'',''/local/dir1'',
''/local/dir1/dir2'' ]:
  ensure => directory,
}

oh, and there are also functions around that help you to "auto"-create
that array. But personally I think this is the wrong approach.

Yes.

Be cautious of gratuitous md5summing that may occur. I''ve seen it
happen
with clients up to 0.25.5, and it cannot be circumvented on those.
Even though no content is being modified, puppet may compute md5sums for
each and every file in the tree you are recursing.
