[Puppet Users] Issue with puppet file serving api not parsing yaml content correctly

I am working on building a facter tag based node classifier similar to
https://github.com/jordansissel/puppet-examples/tree/master/nodeless-puppet/.
However, I have run into an issue where I cannot use puppet''s require
file ability to push the yaml file containing the facts file to the
client because it would require two runs of puppet to pickup changes.
Consequently, I have written into the facter ruby script the ability
to connect to puppet''s restful api and get the yaml file from the
private store. This works fine in irb, ruby, and facter if called
directly. However, when run inside of a puppet run it seems to fail on
parsing the http response correctly into yaml. As a result, it does
not get saved to disk and loaded as a fact for the puppet run.

There is probably a simpler way to do this. Essentially we want to
have tags on a server and use that to selectively include or remove
modules from a server by facter tags rather than by a server''s name.

Some Version Information:
- os = CentOS release 5.2 (Final)
- ruby = ruby 1.8.6 (2008-08-11 patchlevel 287) [x86_64-linux]
- facter = 1.6.0 (updated because my script loads multiple facts and
the older version we were running requires the filename to match the
fact name. This was not working because I did not want to split my
ruby load script into multiple files to match each of the fact names.)
- puppet = 0.25.4

Yaml file it is trying to grab from a private store:
---
role:
  - base
  - db
env:
  - dev

The yaml file downloads correctly via a puppet run without my script.
I can also wget the file and use net/https via ruby to get the file.
All methods return the correct file with matching md5sums.

Under my module called "truth" I have the following:
- files -> private -> domain.inter -> hostname -> truth_tags.yml
  ex:
---
role:
  - base
env:
  - dev

- lib -> facter -> load_truth_tags.rb
  problem area:
def apitruthtag(calltype)

  # set some client side variables to build on later
  sslbasedir = ''/etc/puppet/ssl''
  sslprivdir = sslbasedir + ''/private_keys''
  sslpubdir = sslbasedir + ''/certs''
  sslcafile = sslpubdir + ''/ca.pem''

  # this sets if we want metadata or content from puppet
  datatype = calltype

  # We want yaml back from puppet
  header = {''Accept'' => ''yaml''}

  # Setup some connection variables to our puppet server and what we
want from it
  proto = ''https''
  server = ''puppet.domain.inter''
  port = ''8140''
  path = ''/production/file_'' + datatype +
''/truth_private/
truth_tags.yml''

  # Build the full uri to request from our puppet server. Then parse
it for port and things
  uri = URI.parse(proto + ''://'' + server +
'':'' + port + path)

  # Setup the http module and set it for getting data
  http = Net::HTTP.new(uri.host, uri.port)
  request = Net::HTTP::Get.new(uri.request_uri, header)

  http.use_ssl = true if uri.scheme == ''https''

  # Enable ssl verification to ensure we are talking to the correct
people
  http.verify_mode = OpenSSL::SSL::VERIFY_PEER

  # Cert Auth:
  # Set certificate paths
  # puppet certificate authority file

  if File.readable?(sslcafile) then
    # Puppet ca file
    http.ca_file = sslcafile
    puts "readable? " + sslprivdir + ''/'' + hostname
+ ''.pem'' if $debug
    if File.readable?(sslprivdir + ''/'' + hostname +
''.pem'') then
      # client private key
      http.key = OpenSSL::PKey::RSA.new(File.read(sslprivdir +
''/'' +
hostname + ''.pem''))
      puts "readable? " + sslpubdir + ''/'' + hostname
+ ''.pem'' if
$debug
      if File.readable?(sslpubdir + ''/'' + hostname +
''.pem'') then
        # client public key
        http.cert = OpenSSL::X509::Certificate.new(File.read(sslpubdir
+ ''/'' + hostname + ''.pem''))

        # Make the request
        response = http.request(request)
      else
        raise "No readable client pubic key in #{sslpubdir}/
#{hostname}.pem"
      end # End public key check
    else
      raise "No readable client private key in #{sslprivdir}/
#{hostname}.pem"
    end # End private key check
  else
    raise "No readable ca cert in #{sslcafile}"
  end # End ca file check

  # Check to make sure we got some data back
  if response != nil
    # Check to see if we have a good server response before saving the
variable
    puts "check code " + response.code if $debug
    if ((response.code < "300") and (response.code >=
"200"))
      return response.body
    else
      raise "server did not return an acceptable reponse code"
    end # end server response code check
  else
    raise "No response from #{server}"
  end # end nil response check

end # end apitruthtag

servermd5 =
YAML.load(apitruthtag("metadata")).ivars["checksum"] #
When executed from a puppet run I tells me that ivars is undefined.

- lib -> puppet -> parser -> functions -> truth_tags.rb
- manifests -> init.pp
ex:
class truth inherits truth::init_bootstrap {
if truth_tag(''role'', ''base'') and
!truth_tag(''role'', ''nobase'') {
		notice("${::hostname}: Including role, base modules...")

		notice("    ${::hostname}: role, base: including network")
		include network
}
}
- manifests -> init_bootstrap.pp
just makes sure the /etc/truth_tags.yml file exists on disk

Process (if the facter yaml load was working):
1. puppet client downloads "lib -> facter ->
load_truth_tags.rb".
2. facter runs with the external ruby fact script.
  - this fails on puppet runs but functions correctly directly in
ruby, irb, and facter itself using "facter -d"
  - If working load_truth_tags.rb would do this:
  1. See if a cached /etc/truth_tags.yml file exists
  2. if it does exist then it md5 hashes the file. Next, it uses net/
https to connect to the resful api to get the puppetmaster''s hash to
see if the local file has changed. If they differ it pulls down the
changed file from puppetmaster and writes it to disk.
  3. if the file does not exist on disk it pulls it down from
puppetmaster using net/https and checks both the server and client
hashes to see if it was modified in transit and that it downloaded the
correct content.
3. Next, manifests -> init.pp loads the truth_tags function from lib
-> puppet -> parser -> functions -> truth_tags.rb for the puppet run.  - the manifest init.pp file is basically a set of rules that says if
role = db then include these other functions. The goal being we don''t
want to classify servers by name but rather by their functions. This
would allow us to be more flexible and not have to worry about double
including things in the nodes.pp file.



Sorry I have not included all of the "load_truth_tags.rb" script as it
is long (317 lines). I can if requested.

Issue I can see which differs from a puppet run vs stand alone ruby
run:

irb, ruby, or facter:
yaml parsed http response = #<YAML::Object:0x2ada01f7cf00>

puppet run:
yaml parsed http response = #<Puppet::FileServing::Metadata:
0x2ac7987b9c08>
with error:

undefined method `ivars'' for #<Puppet::FileServing::Metadata:
0x2ac7987152c0>
#<NoMethodError: undefined method `ivars'' for
#<Puppet::FileServing::Metadata:0x2ac7987152c0>>

It appears that yaml is not parsing correctly when run inside a puppet
run. As a result, the response.body.ivars["checksum"] variable is not
being set. Any ideas?

I''m finding it difficult to work out what your actual problem is.

To back up a little...

"There is probably a simpler way to do this. Essentially we want to
have tags on a server and use that to selectively include or remove
modules from a server by facter tags rather than by a server''s
name."

If you''re looking everything up by hostname anyway, why not just have
an
external node classifier that does all this logic server-side?

Re: [Puppet Users] Issue with puppet file serving api not parsing yaml content correctly

So ...

What does the output of apitruthtag("metadata") show you between each
run in facter, irb and puppet? Can you output each to a file and
analyze the difference?

So when you run it with all the Puppet libraries the YAML object is
being serialized back into a Ruby object Puppet::FileServing::Metadata
... I''m really curious what the raw YAML output looks like. This
should only happen I think if the YAML output has meta information
that matches that class type for example:

 ---
!ruby/object:Puppet::FileServing::Metadata {}

I get the feeling the YAML you are getting back isn''t what you were
expecting and looking at the contents of the raw output might give a
better clue as to why.

[Puppet Users] Re: Issue with puppet file serving api not parsing yaml content correctly

Thanks for everyone''s help. I figured out what the issue was over the
weekend. It appears that when the ruby script is run in a puppet run,
puppet loads the yaml dictionaries specific to puppet. However, when I
was testing the script in ruby I was not loading the yaml dictionaries
for puppet. This was causing my script to get a generic loaded yaml of
#<YAML::Object:0x2ada01f7cf00> instead of the correctly loaded yaml
#<Puppet::FileServing::Metadata:0x2ac7987b9c08>. When the dictionaries
are loaded for puppet it no longer has an "ivars" hash with content or
metadata. I just needed to do
"YAML.load(apitruthtag("content")).content" instead of
"YAML.load(apitruthtag("content")).ivars["content"].

However, because I am still not loading the dictionary outside of the
puppet run my script will not function correctly if just executed in
ruby. Does anybody know how to properly load the puppet yaml
dictionary outside of a puppet run?

FYI:
The raw yaml data from puppet is:

--- !ruby/object:Puppet::FileServing::Content
content: |
  ---
  role:
    - base
  env:
    - dev

You should be able to load it as

require ''puppet/util/zaml''

and use ZAML instead of YAML.  That''s the version of YAML
we''re vendoring to
fix a whole list of bugs we ran into.

There''s more complication going on in:

lib/puppet/util/monkey_patches.rb

showing how we monkey patch the various yaml methods on objects to actually
talk ZAML instead.

Thanks. Unfortunately, it seems I will need to wait until we upgrade
puppet as version 0.25.4 does not seem to have
''puppet/util/zaml''.

Then I''m more confused :)

does

require ''puppet''
require ''yaml''

just do the right thing? If not, I''d post to the puppet-dev list and
see if
the more developer-focused crowd can give you a better answer for 0.25.4.

[Puppet Users] Re: Issue with puppet file serving api not parsing yaml content correctly

Unfortunately, it does not work. That was the first thing I had tried
to try and reproduce the problem in ruby outside a puppet run.

Also, here are the ruby util modules for puppet in 0.25.4:

/opt/ruby-1.8.6-p287/lib/ruby/site_ruby/1.8/puppet/util
autoload
autoload.rb
backups.rb
cacher.rb
checksums.rb
classgen.rb
config_store.rb
constant_inflector.rb
diff.rb
docs.rb
errors.rb
execution.rb
feature.rb
file_locking.rb
fileparsing.rb
filetype.rb
graph.rb
inifile.rb
instance_loader.rb
ldap
ldap.rb
loadedfile.rb
logging.rb
log_paths.rb
log.rb
metaid.rb
methodhelper.rb
metric.rb
monkey_patches.rb
nagios_maker.rb
package.rb
pidlock.rb
posix.rb
provider_features.rb
pson.rb
queue
queue.rb
rails
rdoc
rdoc.rb
reference.rb
resource_template.rb
selinux.rb
settings
settings.rb
storage.rb
subclass_loader.rb
suidmanager.rb
tagging.rb
user_attr.rb
warnings.rb


Also, I did not see anything in the monkey_patches.rb file pertaining
to a yaml like patch only rdoc.:

module RDoc
    def self.caller(skip=nil)
        in_gem_wrapper = false
        Kernel.caller.reject { |call|
            in_gem_wrapper ||= call =~ /#{Regexp.escape $0}:\d+:in
`load''/
        }
    end
end

I think at this point we will probably upgrade puppet anyways so I
will just add "require puppet/util/yaml" once we have upgraded.
