[Puppet Users] how to exec a directory creation before downloading a file to that directory?
I want to create a directory and THEN get files into that directory on
a client.
Puppet it seems does not follow the order of commands, like below in
my example.
Sometimes it creates the directory, then downloads the file, and
sometimes it tries to download the file before creating the directory,
so the file won''t be downloaded.
How can I download a file and make certain the destination directory
will be there before this file is downloaded? thanks again! -jason
class theclass (
exec{''mkdir -p /opt/scripts'':
unless => ''test -d /opt/scripts'',
}
file { "/opt/scripts/my_script.sh":
owner => "root",
group => "thegroup",
mode => 770,
source => "puppet:///files/my_script.sh",
}
)

Re-do that as:
class theclass {
file { "/opt/scripts":
ensure => "directory",
owner => "root",
group => "root",
mode => 755,
}
file { "/opt/scripts/my_script.sh":
owner => "root",
group => "thegroup",
mode => 770,
source => "puppet:///files/my_script.sh",
require => File[''/opt/scripts''],
}
}
That way, it won''t copy down my_script.sh without first creating
/opt/scripts.

Interestingly enough, I learned about the require keyword when I did this same thing, but left out the ''require''. And (even using 0.24.8), I had problems where it tried to copy the file into a non-existent directory. Adding the ''require'' line made that go away... David P.S. BTW, Jason, the root cause of your confusion is that you are approaching this as a procedural/functional thing, instead of a ''state'' problem. What you should be doing with puppet, 99.9% of the time, is describing the state that you would like your system to be in, and then let puppet take care of the details. I.e., if you find yourself writing ''exec'' statements to do stuff like create directories, then you''re probably doing it wrong. Note the benefits: if the /opt/scripts directory exists but is set to 0200, or is owned by a user, or has a group ownership of uucp, then puppet will fix it. In your ''exec mkdir'' scenario, all puppet would do is see if the directory exists. Using puppet to it''s fullest potential takes a shift in how you think about the problem, but it''s generally worth it. Note: I''m nowhere near "there"! I''m a newbie on the road, same as you...

Puppet won''t just create directories that aren''t defined, but if you have: file { "/opt/foo": ensure => directory, ... } file { "/opt/foo/file": ... } then you don''t need to explicitly do the require as Puppet will ensure the parent directory is applied before the child.> > David > > P.S.

Hi, I was wondering this too last week. I haven''t tested this yet, but I assume using "require" and "before" would do the trick: http://reductivelabs.com/trac/puppet/wiki/TypeReference Samuli> > I want to create a directory and THEN get files into that directory on > a client. > Puppet it seems does not follow the order of commands, like below in > my example. > Sometimes it creates the directory, then downloads the file, and > sometimes it tries to download the file before creating the directory, > so the file won''t be downloaded. > > How can I download a file and make certain the destination directory > will be there before this file is downloaded? thanks again! -jason > > class theclass ( > > exec{''mkdir -p /opt/scripts'': > unless => ''test -d /opt/scripts'', > } > > file { "/opt/scripts/my_script.sh": > owner => "root", > group => "thegroup", > mode => 770, > source => "puppet:///files/my_script.sh", > } > > ) > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
