I have a situation where I am trying to manage some systems that have
a single IP address but different ssh port numbers. For each of these
systems I need to individually manage a logrotate.d configuration
file, and a separate archive directory.
Of course, this won''t work...
file {
"/data/syslog/${remote_host}/archive":
ensure => directory;
"/etc/logrotate.d/syslogng-host-${remote_host}":
content =>
template("syslog-ng/etc/logrotate.d/server.erb");
}
Puppet complains for the first entry that the file is not unique,
since I am trying to call it multiple times with the same
$remote_host. If the directory already exists, that''s great. How can I
make puppet skip it in that case? The puppet docs at
http://docs.reductivelabs.com/references/stable/function.html state
that there is an "if defined" function, but I''ve never gotten
this to
work, and the documentation really isn''t very clear as to if functions
are supposed to work inside a manifest.
I tried this:
file {
if ! defined(File["/data/syslog/${remote_host}/archive"]) {
"/data/syslog/${remote_host}/archive":
ensure => directory;
}
}
and this:
if ! defined(File["/data/syslog/${remote_host}/archive"]) {
file {
"/data/syslog/${remote_host}/archive":
ensure => directory;
}
}
.... both of which resulted in errors. As I said, the documentation
really isn''t clear if functions CAN be used inside a manifest. That
has always confused me and I wish someone would clear up the docs.
For the second entry, I can simply make it unique by suffixing the
unique ssh port number. That''s not an option for the first file
though.

In general I try to avoid defined, as in my opinion this is some kind of codesmell. But there are valid situations for that function. regarding to functions: they go into manifests. Where else do you imagine they could go? I mean if not in manifests you might assume that they could go somewhere else. And maybe you could raise a ticket about that point where documentation is not clear.

Functions can absolutely be used inside of manifests.
You may be running into an issue in that ''defined'' works based
on the
compile time order of your manifests.
Example:
class foo { ... }
class bar { ... }
# This does not work as expected
if ! defined(Class["foo"]) { ... }
include "foo"
# This does
include "foo"
if ! defined(Class["foo"]) { ... }
So, I''m guessing that whatever you''re trying to do is
including that
compile statement in an ordered include that you''ve already called.
Does that make sense?
