The problem is that there's no good primary key for these changes. From
looking at your troubles, it seems that it might be much more usable if
the augeas type operated more on the level of 'I am going to change a
certain part of the tree to look exactly like this'. To pick the part of
the tree, you'd specify a path expression, for example
'/files/etc/hosts/*[ipaddr="127.0.0.1"]', and also a path that can be
used when the entire entry is missing, say '/files/etc/hosts/01'.
Writing down what you want that subtree to look like will also be
interesting. Puppet doesn't have data structures to do that, so you'd
have to encode them in a string, e.g. using the tree notation that
Augeas itself uses.
With that, we'd have a type that looks more like this:
augtree { "etc-hosts-localhost":
find => "/files/etc/hosts/*[ipaddr = '127.0.0.1']",
create => "/files/etc/hosts/01",
tree => " { ipaddr = 127.0.0.1 } { canonical = localhost } { alias =
local.local } "
}
The above would make sure that your entry for localhost looks a certain
way, and would not require any gymnastics with onlyif to become
idempotent. Similarly, to make sure that localhost has an alias of
'host.example.com', you would write
augtree { "etc-hosts-localhost-alias":
find => "/files/etc/hosts/*[ipaddr = '127.0.0.1']/alias[ . =
'host.example.com']",
value => "host.example.com"
}
With that, it would be reasonable to not allow two augtree resources
with the same find parameter.
Of course, there's the small issue of implementing a type like the
above. The full docs would look something like
augtree {
find => "..." # Path expression matching the subtree to work on;
mandatory
create => "..." # Path expression to use when find doesn't match at
all; optional, use value of 'find' by default
tree => "..." # The tree that should be there underneath 'find'
value => "..." # The string value to assign to the tree node 'find'
}

Yes, that's one way to do it - you could base that provider off Augeas;
the heart of it would be a method like (needs to be split up a bit to
mesh with Puppet's notion of checking if a change is needed, reporting
what has changed, and noop mode)
def append_module(module)
aug = Augeas::open("/", Augeas::NO_MODL_AUTOLOAD)
begin
aug.set("/augeas/load/Xfm/lens", "Shellvars.lns")
aug.set("/augeas/load/Xfm/incl",
"/etc/sysconfig/kernel")
aug.load
mod_path = "/files/etc/sysconfig/kernel/MODULES_LOADED_ON_BOOT"
mods = aug.get(mod_path) || ""
unless mods.split().include?(module)
mods = mods.split().push("x").join(" ")
aug.set(mod_path, mods)
aug.save
end
ensure
aug.close if aug
end

It doesn't need new features, but it would require that you change the
stock shellvars lens so that it treats the MODULES_LOADED_ON_BOOT
special, and splits it into several tree nodes.

[Puppet Users] Issue with '|'
I have a question hopefully someone here can help me out with. I have a
module that I didn't write, I got it from the github. it's the postgres
module. I'm running on CentOS 5. In the module there is this:
case $ensure {
present: {
exec { "Create $name postgres db":
command => "/usr/bin/createdb $ownerstring $name",
user => "postgres",
unless => "/usr/bin/psql -l | grep '$name *|'" *** This
line causes an error
}
}
The *** line causes puppet to error out like so:
debug: //Node[myhost.mydomain.com]/Postgres::Role[voiceob]/Exec[Create puser
postgres role]: Executing check '/usr/bin/psql -c '\du' | grep 'puser *|''
debug: Executing '/usr/bin/psql -c '\du' | grep 'puser *|''
err: //Node[myhost.mydomain.com]/Postgres::Role[puser]/Exec[Create puser
postgres role]: Failed to retrieve current state of resource:
(This produces no output if the user doesn't exist in postgres.)
Nothing more on the error line. Interestingly enough, if I remove the '|'
(pipe) after the psql part of the command, it doesn't error. However, it
doesn't do what I need it to do. I have tried it without the unless line
and it works perfectly. Again, it doesn't do what I need it to do that way
though. I have searched the message boards and wiki to no avail.
Can any of you shed some light on why this wouldn't work?
TIA

[Puppet Users] 'checkinstall' for custom package creation
One problem that we frequently run into while building and supporting puppet infrastructures, is some cowboy developer who insists that he needs Python 3.1, PHP6, SWiG 1.3.40, etc, and these packages are not available in our Distro's stable package repository. Have you ever tried to build a slotted Python RPM in RHEL? Pardon my lack of RHCE, but it can be rather time consuming! I recently came across a project called "checkinstall" http://www.asic-linux.com.mx/~izto/checkinstall/ Checkinstall acts as a wrapper for `make install`. When you compiled your copy of php7(or whatever crazy version your developers require..) : ./configure ; ./make ; ./make check ; checkinstall make install Check install will ask you if you would like to build RPM, Deb, or a Slackware package (for the 5 remaining Slackware users out there.) You can also specify some basic dependencies and provides meta-data in your package. I've only used checkinstall for a few small packages, however the tool could be very useful to some of the lazy puppet admins out there who need to support crazy versions of various packages via puppet. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

OK, thanks for pointing this out. Looking back at it now, I think I was
probably counting on ssh_authorized_key requiring File[$home/.ssh]. But
that doesn't seem to be explicit anywhere, so I'll add it in explicitly for
the next point release. And the user too, while I'm at it.

I'll have to spend a little time looking into this. The whole purpose of
the way I set up the defines and virtual resources was to be able to
override parameters. The last time I tried it, it worked. I guess it's a
conflict with the file resource in your manifest? I'll see what I can
figure out and get back to you.

We do this by defining the service account as a virtual user and
realizing/overriding when necessary. For your example:
@user { "apache":
uid => 48,
gid => 48,
groups => "apache",
}
Then in your nagios module:
Realize(User["apache"])
User["apache"] { groups +> "nagios" }
Don't forget to realize it in your apache module too. :)

Sorry if I wasn't clear in the original post. I've definitely looked at the contents of the environment (dump of env) and there is no difference in the two calling contexts. I've also dumped the contents of System.getProperties() (equivalent of Java's environment) and again there is no difference in the two calling contexts.

I think so. As a systems engineer, I reach for python and ruby very frequently and can't remember the last I reached for C/C++. I believe it was to write a cfengine module actually. Puppet provides a natural way for me to integrate the scripting I already do day to day into a sophisticated and robust system. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Following Craig's suggestion, you might consider looking at the CLASSPATH environment variable. I strongly recommend against relying on CLASSPATH, by the way, as doing so is prone to problems exactly like this. Instead, specify your classpath on the command line. Even better: package all the needed classes (except those from the standard runtime library) into the same jar, identify the entry point via a Main-Class: entry in its manifest, and run the sucker using "java -jar". You mention that you have checked permissions, etc.. I assume, then, that you are aware that if the puppetd process does not have read permission on one or more of the needed jars, or, recursively, the directories containing them, then those jars are effectively not in the classpath. Also, do you give the *absolute* path to each jar in your classpath? One more thing: does your initscript use the absolute pathname of the java runtime executable? If not, and if there is more than one Java runtime installed, then it may be that puppetd is running a different java than you do from the command line. That might contribute to your issue.

'ip_of()' is what Puppet calls a 'function', right?
Does anyone have a reference on how to write them -
the reductive labs docs seem a little broken today.
Or better still, has someone already written such a thing :)
As a matter of fact, yes, I have. :-)
In my "nsc-puppet-utils" module, I have a function resolve_ipnets()
which does that. (It does have some additional features as well.
For example, it resolves names on the form "foo.example.com/24"
to "10.20.30.17/24", and it handles lists of hostnames as well.)
Do a 'git clone http://www.nsc.liu.se/~bellman/nsc-puppet-utils.git'
to get my module. There is documentation inside the file
plugins/puppet/parser/functions/resolve_ipnets.rb.
A little note, though. If you use this to populate /etc/hosts from
DNS, and you do so on your Puppetmaster, you won't be able to change
the address of that name. The next time resolve_ipnets() is called,
it will find the address in /etc/hosts, and then you're stuck. (You
can of course remove that entry from /etc/hosts manually, and then
you'll be OK again, but that's cheating. :-)

[Puppet Users] Correct user management across modules
I've got an Apache module and a Nagios module which "require"s the
Apache module, in the Nagios module we need to add the apache user to
the nagios group, what would be the best most scalable method to do
this? Assuming we might have other modules for webapps which need to
add the apache user to other groups in the future?!
The actual apache user is created by the httpd package (on RedHat) but
in the Apache module can we just manage the user with something like :
user { "apache":
uid => 48,
gid => 48,
groups => "apache",
}
and then in the Nagios module do
User["apache"]{ groups +> "nagios" }
? Or is there a better way?
Cheers!

[Puppet Users] ssh::auth server dependency on ~/.ssh and a scoping question
Hi Andrew,
Just noticed that ssh::auth::server doesn't require the resource for ~/.ssh
directory. Considering the documentation says it does (in Examples -> 1. With
account management at the bottom mentions that 'require => [User[$title],
File["$home/.ssh"]]' is implicitly included in both client and server), I
thought I'll report it.
This works fine for ssh::auth::server because it uses a file resource for the
~/.ssh/$filename file, so ~/.ssh is autorequired by puppet (if defined).
Also, while I'm at it, I wanted to ask a question related to scoping. Don't
know if it's another difference between puppet 0.24.8 and 0.25.x, can't find
any
docs mentioning that. Anyway the problem manifests itself in that simple
manifest:
import "auth.pp"
include ssh::auth
Ssh::Auth::Key { length => 4096 }
ssh::auth::key { 'foo': }
include ssh::auth::keymaster
file { '/home/foo/.ssh': ensure => directory, mode => 700, owner => 'foo',
group => 'puppet' }
ssh::auth::client { 'foo': group => 'foo' }
this is a simplified manifest which I ran with standalone puppet and it
produces the following error:
Only subclasses can override parameters at /root/puppet-
tests/sshauth/auth.pp:113 on node ...
The problem here is the "group => 'foo'" param passed to ssh::auth::client.
It doesn't really matter which parameter it is though as the issue seems to be
that the ssh::auth::client (or ssh::auth::server) define cannot override
properties of a resource declared in ssh::auth::key define.
I searched a bit for something on defines overriding parameters of resources
and found a thread here on puppet-users [1] which implies this isn't possible.
Does that work in 0.25.x ?

Re: [Puppet Users] parsedfile provider documentation?
Hi David,
I was just looking a bit more into augeas:
Is there a way to set variables in augeas wit values obtained by a
'get' statement?
Like:
...
augtool> get /files/etc/sysconfig/kernel/MODULES_LOADED_ON_BOOT
/files/etc/sysconfig/kernel/MODULES_LOADED_ON_BOOT = "ipv6"
...
Thus having a variable $oldval with values 'ipv6' which I could reuse
to set the value again. In this way an appending of values would be
easy, e.g.:
...
augtool> set /files/etc/sysconfig/kernel/MODULES_LOADED_ON_BOOT "$oldval sunrpc"
Thanks and bye,
Frederik
