Re: [Puppet Users] function that returns parameters from a webservice

[Pearl Raj]

Peter and Henrik, thanks for writing in. 

Let me explain the scenario once. We use puppet 3 with Hiera for appX 
application. But due to some internal issues (management, company policy), 
the team which supports the application (Support-appX) do not have access 
to Hiera and those who manages Hiera (Support-Hiera) refuses to update 
Hiera parameters and instead has suggested a work around - to avoid Hiera 
and to replace it with a webservice which essentially mimics Hiera. 

1) Sample Webservice which returns host specific json hash
-

from flask import abort
{
  "hosts": [
{
  "description": "host vm 1",
  "done": false,
  "id": 1,
  "title": "xyz",
  "role" : "agent"
 },
 {
  "description": "host vm 2",
  "done": false,
  "id": 2,
  "title": "abc",
  "role" : "loadbalancer" 
 }
  ]}@app.route('/appX/hosts/', methods=['GET'])def 
get_host(host_id):
host = [host for host in hosts if host['id'] == host_id]
if len(host) == 0:
abort(404)
return jsonify({'host': host[0]})


So calling http://localhost:5000/appX/hosts/2 
will return the following json 
hash corresponding to host vm 2 (only representational)

{
  "description": "host vm 2",
  "done": false,
  "id": 2,
  "title": "abc",
  "role" : "loadbalancer"
 }


2) Create a puppet module with a function "get_host_hash" which essentially 
returns the above json hash as in the following example :

(ruby example - this need to be replaced by a puppet function get_host_hash)

require 'net/http'

url = 'http://localhost:5000/appX/hosts/2 
'
resp = Net::HTTP.get_response(URI.parse(url)) # get_response takes an URI object

return resp.body 


3) Write a class to retrieve config for host

class new_appx_class {
$config = get_host_hash ($::hostname)
$role = $config['role']

#calls roll specific wrapper class that passes parameters to underlying 
appx puppet classes

class { "appx::$role":
config => $config
}
}

4) Wrapper classes for different roles

class appx::loadbalancer($config) {
class {'lvs'::real_server':
  param1 => $config['lvs::real_server']['param1']
  paramx => $config['lvs::real_server']['paramx']
}

class appx::agent($config) {
class {'lvs'::agent':
  param1 => $config['lvs::agent']['param1']
  paramx => $config['lvs::agent']['paramx']
}

My doubt is about step 2. Whether it is possible to write a puppet function 
get_host_hash to call the webservice.  

Thanks and Regards,
Pearl

[Puppet Users] Broken puppetdb

[jdehnert]

Greetings All,

I decided to try and implement the puppetlabs-puppetdb and 
puppetlabs-postgres modules after I had both puppetdb and postgres 
installed and working on my puppet server.  This was ill advised as it 
broke my working setup and no amount of re-configuring seems to be able to 
get things working again.   

I finally pulled the manifest that "describes" my configuration, but now I 
cannot seem to get puppetdb working at all.  My clients are giving me these 
kind of errors:

Error: Could not retrieve catalog from remote server: Error 400 on 
SERVER: Failed to execute 
'/pdb/cmd/v1?checksum=2b3883d84fd2c7f9899bd6280247edbccc31cf15=4=it-lnx-01.myhost.com=replace_facts'
 
on at least 1 of the following 'server_urls': 
https://puppetmaster.myhost.com:8081
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

I have crawled through  the puppet docs to try and fix my configurations, 
but I can't seem to get things operating properly. 

It seemed pretty clear that I did not need to configure the SSL portion of 
puppetdb, but these errors seem to be flying the the face of what I read.

Do I need to configure SSL for puppetdb to get it to work?  and  What's my 
best chance of getting things working again.  Start from scratch, or am I 
just overlooking something from my configs.?

Thanks,
  jdehn...@gmail.com

[Puppet Users] Re: Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class

[Luke Tinker]

Looks to actually be an issue with selinux,
im still looking into it as its not actually logging the issue,
but setting selinux to permissive is resolving the problem,

since this isn't a puppet issue i was barking up the wrong tree.

[Purpose of this exercise is to replace hiera]


In recent 4.x version of puppet, you can use "data in modules and 
environment" using the lookup function. It provides an alternative way 
of looking up data to hiera in that you can write a function (named 
mymodule::data() for a module, and environment::data() in an 
environment. Those functions can be written in the puppet language.


You will still need a function that makes the http call and transforms 
the result back to a hash.


BTW: You can certainly return a hash from a custom function.

What you get with hiera (lookup in later versions of puppet) is also 
automatic data binding of class parameters. That kind of data injection 
is the recommended way to set parameters as it makes your code a lot 
cleaner and more flexible to control.


If you just write an arbitrary function you miss out on the automatic 
data binding. If you instead wrap that into the data() function 
supported as a "backend" (data provider) for lookup you will get both 
things.

Re: [Puppet Users] Unexpected behavior when using variable interpolation on a subkey in hiera

Is the hiera_hash function doing the same from within puppet?

The template generated on the host also reflects the fact that the extra

*Subject:* [Puppet Users] Unexpected behavior when using
variable interpolation on a subkey in hiera

Greetings,

I'm having trouble using hiera variable interpolation on a
sub-key. It appears that along with interpolating the variable,
hiera is also returning the un-interpolated data as well, which
is causing issues because the un-interpolated data is nonsense.
I'm currently running Hiera 1.3.4 and Puppet 3.8.5 on RHEL6.

Here's an example of what I have in hiera:

# common.yaml
somekey:
"%{::clientcert}":
subsubkey: "data"

And here's what I get when I query hiera directly:

$ hiera -h somekey
{"myhost.example.com
"=>{"subsubkey"=>"data"},
 "%{::clientcert}"=>{"subsubkey"=>"data"}}

Oddly enough, if I run it without the -h flag, I only get the
un-interpolated data.

$ hiera somekey
{"%{::clientcert}"=>{"subsubkey"=>"data"}}

Based on my reading of the docs[1], in both cases I would expect
to get back: {{"myhost.example.com
"=>{"subsubkey"=>"data"}}

I also tested variable interpolation with the value of
subsubkey, and hiera properly interpolated it correctly, even on
the returned entry where %{::clientcert} was left un-interpolated.

Initially I thought this was somehow related to deep_merge, but
I tested it out by disabling deep_merge (removing the
merge_behavior key) and I get the same results.

Am I misunderstanding how interpolation on sub-keys in hiera
should work, or is this unintended behavior?

Thanks,

Aaron

Re: [Puppet Users] function that returns parameters from a webservice

[Peter Kristolaitis]

You can write custom functions[1], but I don't think they can return a 
hash -- only a single value.  This functionality is designed for things 
like calculating password hashes, etc, not generalized data lookup.  
This is probably also completely the wrong approach, in the Puppet 
model, if your goal is to parameterize entire classes.


A much better solution is to keep Hiera, but write a custom backend[2] 
to integrate the data returned by your API into Hiera's structure.  This 
keeps all the benefits of Hiera while also giving you back-end flexibility.

[Puppet Users] Augeas help

[mike r]

Hello, Im tryign to use Augeas in my manifest to manage /etc/fstab file

specifically I want to make sure my /etc/fstab file has the following line

/tmp /tmp nodev,noexec 0 0


Augeas syntax is like learning Chinese, Im trying to make my manifest 
figure out whether 

1) /etc/fstab has a line ^/tmp, if not add a new line with /tmp

2) if this line exists, then if it has nodev option, if not, append the 
'nodev' to this line (/tmp nodev)

3) if this line exists, check if noexec option is there, of not, append to 
the line (/tmp nodev, noexec)

anyone have idea how to actually write this out? Thanks.

Re: [Puppet Users] Git Repo Strategy

[Rich Burroughs]

I'm assuming this could be done. We're talking about UNIX she'll commands
and there's a way to do just about anything. But I can't imagine it being
simple or fun to use. Like could you do Pull Requests on Github between
these repos? Maybe, depending on how you set it up. People nowadays
recommend against monolithic repos too, and that's what you'd have. You'd
just have a bunch of them.

The normal recommended workflow with r10k is using branches for those
environments, not separate repos. Then you have the ability to merge
between branches, so it's easy to promote those changes along your pipeline.

I remember back before I started using r10k, it seemed very confusing to
me. I think there's a bit more info out about it now. In terms of getting a
Puppetfile setup, one of the hard things there is that you need to account
for all of the dependencies. Rob Nelson made this cool Ruby gem that makes
generating the file a bit easier. You can pass it a set of Forge modules
and it will also include their dependencies:

https://github.com/rnelson0/puppet-generate-puppetfile/blob/master/README.md

It's pretty slick.

Personally I'd recommend you stick it out and figure out how to make r10k
work for what you're doing. I would bet you'd be glad you did after. If you
have problems ask specific question here or IRC or Slack. There are a lot
of people using it now and there should be lots who can help.

Yes it would be time consuming. It's worth the time. An upgrade would probably

Been there, tried it, moved to r10k. The above is a great way to see your 
environments drift over time.

If you want each environment to be a separate git repo you can, but it sounds 
like you may as well have them all as branches in a single git repo. That way 
you can at least diff different branches easily and cherry pick single changes 
from one to the other.

What is QA for, in this scenario? Determining that you've brought up the 
correct set of changes from dev? If so, why not use git itself to prove that 
you've brought up the correct changes, as specified by git commits, to your 
mainline branch?

[Puppet Users] Git Repo Strategy

[Funsaized]

Hello, 

I am relatively new to puppet and am trying to develop a good workflow in 
conjunction with git/github to keep a better version control system. The 
version of puppet that I am working with and has been implemented is a bit 
dated, and using R10k and developing a puppetfile would be quite time 
consuming. I know that R10k and dynamic environments is the recommended way 
of doing things, though for now I'm not sure if its the best for my 
scenario and how everything has been previously set up. My question is is 
there a simple way to just map one git repo for each environment (dev, QA, 
production, etc). That way changes could be made in the dev environment, 
then moved over to the correct repos when the changes are confirmed in 
order? Would this be as simple as declaring each folder withing the 
/puppet/environments folder as a git repo and controlling that way? 

Deployment strategy

-   Upload changes to Dev repo

-   Deploy Dev changes to Dev master

-   Test

-   Merge Dev changes to QA repo

-   Rinse and repeat

You can use the same operators to express dependencies between classes.

I changed my config accordingly:

:hierarchy:
  - "nodes/%{::fqdn}"
  - "%{::operatingsystem}"
  - "%{::osfamily}"
  - common

Thank you!

RE: [Puppet Users] Unexpected behavior when using variable interpolation on a subkey in hiera

[Johan De Wit]

Hi,



running hiera from the command line, you have to provide the variables you use 
yourself like 



hiera somekey clientcert=node.example.net



Here is some reading

https://puppet.com/blog/debugging-hiera

Subject: [Puppet Users] Unexpected behavior when using variable interpolation 
on a subkey in hiera

Greetings,

I'm having trouble using hiera variable interpolation on a sub-key. It appears 
that along with interpolating the variable, hiera is also returning the 
un-interpolated data as well, which is causing issues because the 
un-interpolated data is nonsense. I'm currently running Hiera 1.3.4 and Puppet 
3.8.5 on RHEL6.

Here's an example of what I have in hiera:

# common.yaml
somekey:
    "%{::clientcert}":
        subsubkey: "data"

And here's what I get when I query hiera directly:

$ hiera -h somekey
{"myhost.example.com"=>{"subsubkey"=>"data"},
 "%{::clientcert}"=>{"subsubkey"=>"data"}}

Oddly enough, if I run it without the -h flag, I only get the un-interpolated 
data.

$ hiera somekey
{"%{::clientcert}"=>{"subsubkey"=>"data"}}

Based on my reading of the docs[1], in both cases I would expect to get back: 
{{"myhost.example.com"=>{"subsubkey"=>"data"}}

I also tested variable interpolation with the value of subsubkey, and hiera 
properly interpolated it correctly, even on the returned entry where 
%{::clientcert} was left un-interpolated.

Initially I thought this was somehow related to deep_merge, but I tested it out 
by disabling deep_merge (removing the merge_behavior key) and I get the same 
results.

Am I misunderstanding how interpolation on sub-keys in hiera should work, or is 
this unintended behavior?

Thanks,

Aaron
