This is not the correct place for Puppet 3.x custom functions (this
location is for custom facts).

The correct location would be mod1/lib/puppet/parser/functions/myfunc.rb.

This is probably why the compiler can't find it.

Given that you're using Puppet 4.x, I recommend using the Puppet 4.x
function API rather than the 3.x API.

As an example for your custom function, in
mod1/lib/puppet/functions/myfunc.rb you would have:

```
Puppet::Functions.create_function(:'mod1::myfunc') do
  dispatch :myfunc do
param :Integer, :arg
  end

  def myfunc(arg)
 "returning value #{arg}"
  end
end
```

And this would be invoked like `mod1::myfunc(1)`.

Cheers,

Peter

Re: [Puppet Users] Re: Encrypting password with custom provider

[Ziwi]

Nevermind the above, I had wrong data { } - it contained hash of hashes, 
instead of hash, and I was referencing wrong variable in the ERB file.

Actually, this works fine. I think so at least, because I am running puppet 
apply on the same machine and I'm not sure if the template actually renders 
on the client. Will check it out soon.

Thanks for pointing to this module Thomas.

Regards,
Eric

Re: [Puppet Users] Re: Encrypting password with custom provider

[Ziwi]

Thomas,

Thanks again for the follow up. I think I will try to use datacat module.

However with the following configuration:

datacat { "/tmp/my.conf":
  template => "my_module/properties.erb",
}


datacat_fragment { 'properties fragment':
  target => '/tmp/my.conf',
  data   => { props => {
  ¦ 'prop1' => "value1",
  ¦ 'prop2' => 'value2',
'password' => 'unencrypted',
  }
 },
}


with erb file in my_module/templates/properties.erb:

<%- @props.keys.sort.each { |prop| 
if prop == 'password'
  @props[prop] = 'encrypt_and_overwrite'
end
-%>
<%= prop -%>=<%= @props[prop] %>  
<%- } -%>



I get an error:

Error: 
/Stage[main]/My_module/Datacat[/tmp/my.conf]/Datacat_collector[/tmp/my.conf]: 
Could not evaluate: undefined method `keys' for nil:NilClass

I assume that it can't render the template on the agent but why?

PS. The sensitive data type sounds nice, but we are using Puppet 3.8 
unfortunately, however I will take a look, as it will be another argument 
to update. :)

Eric

The puppet way to collect data from the client is to create facts.
https://docs.puppet.com/facter/3.5/custom_facts.html

But i doubt having credentials in facts are a good thing, as they are
transmitted to the puppet server  and saved stored in reports (saved as
yaml files and if configured also to PuppetDB). IMHO also parameters of
classes and resources are stored. You have to be aware of this when you
start managing credentials.

There was just recently a sensitive data type introduced
(https://docs.puppet.com/puppet/latest/reference/lang_data_sensitive.html)
which should prevent storing it at too many places. Havent looked into
it in details.

[Ziwi]

Thanks for the link, I will definitely look at this. If this actually 
renders on agent it could come in handy.

However different outputs of the encryption command are still a problem, as 
there should be some kind of: onlyif => decrypt('old_value') != 
plain_password functionality for this.

If anyone has some straightforward examples of using an exec on agent to 
collect data and reference them in manifests in the type/provider manner 
please share.

Thanks again for your answer Thomas.

Best regards,
Eryk Kozakiewicz

[Puppet Users] PuppetConf talk recommendations?

[Rich Burroughs]

You may have already heard but the PuppetConf videos are posted:

https://www.youtube.com/playlist?list=PLV86BgbREluVjwwt-9UL8u2Uy8xnzpIqa

I wasn't able to attend and I'm wondering if there were talks people really
like that they'd recommend watching :)

[Puppet Users] Encrypting password with custom provider

[Thomas Müller]

You could use the datacat module. It runs the template on the client instead of 
on the puppet master.

[Puppet Users] Encrypting password with custom provider

[Ziwi]

Hey guys, I've got an issue, which I think is solvable by using custom 
types/provider but I'm not very familiar with ruby yet, so I'm in very much 
need of your help.

The problem:

I have a file resource which uses a template:

file { "${config_dir}/foo":
¦ ensure => 'file',
¦ content => template('my_module/properties.erb')
}


The template my_module/properties.erb is iterating the properties:

<%- @props.keys.sort.each { |prop|  -%>
  <%= prop -%>=<%= @props[prop] %>
<%- } -%>

The props parameter is a hash:

$props = {
¦ 'username' => "${user}",
¦ 'password' => "${password}",
(...)
}


Now what I need to do is to encrypt the password variable before inserting 
it into the template. The catch is that the encryption is done by custom 
script which HAS to be run on the node (it creates a fingerprint of the 
machine).

Also, unfortunately the encryption generates different hash every time it 
runs, so it should include a check with a decryption (which the encryption 
script provides)


My question is how to achieve my goal so that I can encrypt the password 
(at node level) before inserting it into the file?

I have 3 thoughs:

1. Use custom fact (this actually works, but is not my solution of choice - 
it's not flexbile, it requires at least one puppet run before it would 
insert a proper fact [the first run would create fact, the second populate 
it], and facts should not be used to store passwords even in hash form)
2. Add new type (like file_encrypt) with a content provider which would 
mimic the behavior of the File resource with just encrypt/decrypt methods 
added, but that would be redundant and ugly.
3. Create a custom provider for the File type which could be used with 
passing the encrypt => true to the File resource but I don't know how this 
could be done.

Please help me, I would appreciate it. :)

Best regards,
Eryk

[Puppet Users] module puppetlabs/motd question?

[Jason McMahan]

I am new to puppet, and git but I had a question surrounding the module 
puppetlabs/motd
When I use this module for my windows servers the spacing is messed up and 
the motd looks jagged per say.

*
hello world * (this should have like 4 trailing white spaces for 
example)


I thought it was how the registry entry was created, defaulting to string 
instead of multi string value or even an array.
I attempted to alter 
# vi 
/etc/puppetlabs/code/environments/production/modules/motd/spec/classes/motd_spec.rb
Line 112 :type=> 'string', 
to 
:type=> 'array',

but the registry key is still created on the windows server as string.

Any suggestions? I tried to add issue on the github project for motd but 
did not see a place to do so.

Thank and I appreciate any help/guidance.

[Puppet Users] Re: Why i cant change my custom types?

Another thing you might want to try is "puppet generate type", a 
experimental feature of puppet 4.6 onwards:

[Puppet Users] function not loaded when .pp file runs through command line >> Error: Unknown function:

[bodik]

hello,

I'm getting into troubles while using rake (not important) for --noop
tests during modules development. Using

puppet apply -e 'include class'

everything works fine, but using .pp file containing exactly the same

puppet apply tests/class.pp

results in "Unknown function:" as shown below, where whole usecase is
documented.

Acording to strace myfunc.rb is found by lstat and fopen in both cases,
but in the latter (error one), myfunc.rb is searched also in gems
directories ...

any advice would be appreciated


thanks
bodik

Re: [Puppet Users] development workflow

[Rob Nelson]

Code Manager is PE only, so if you're using opensource then r10k it is. I
still use r10k with PE, though, because CM is missing the equivalent of
'r10k deploy module'. Both work very well.

Since custom types are native ruby code, the puppetserver is restricted in 
what it can do with it. Once the code is loaded into the process, it 
remains there. To get rid of it without trashing your whole environment, 
restart the puppetserver service. The newly started puppetserver will read 
the custom type afresh and have the new code then available for your 
testing.


Cheers, David

[Puppet Users] Why i cant change my custom types?

[Akai]

Hello Together,

i have a strange behaviour wich i cant explain myself. I want to create a 
new custom type (and later a provider) who can configure our own created 
software. For this, i createt a test module and put there everything for my 
development. It looks like this 

.
├── lib
│   └── puppet
│   ├── provider
│   └── type
│   └── custom_type.rb
└── manifests
└── init.pp


In Module development, my steps would be this:

1. Make changes
2. appy on a node
3. Make changes
4. ...

But if i apply a module who uses a custom type, i only can make changes 
until i never use this custom type on a puppetmaster before. It looks like, 
the puppetmaster "remembers" the custom type and every change results in a 
failure. If i reset my puppetmaster, add the changed custom type, 
everything works fine. Let explain me this in code, because my english is 
not so good:

For example i have a very emtpy custom_type

Puppet::Type.newtype(:custom_type) do
  newparam(:name) do
isnamevar
  end
 end

and the init.pp from my module looks like this:

class type_test{

   custom_type { 'aname':
   }
}

It works fine if i apply this.

When i add now a  new parameter for example:

Puppet::Type.newtype(:custom_type) do
  newparam(:name) do
isnamevar
  end

  newparam(:envid) do
# validate is tring or false
validate do |value|
  unless value.is_a?(String)
raise Puppet::Error, 'Parameter envid is not a string.'
  end
end
  end
end

and i apply this by the new init.pp

class type_test{
custom_type { 'aname':
envid => '78121-1239--1231',
}
}

he gives me the following failure:

Could not retrieve catalog from remote server: Error 400 on SERVER: Invalid 
> parameter envid on custom_type[aname] at 
> /etc/puppet/environments/development/modules/type_test/manifests/init.pp:8 
> on node xyz
>

The strange this is: If i reset now my puppetmaster on a older snapshot and 
apply the new version of my custom_type.rb and init.pp again. everything 
works fine. I have this on every change, for example, adding more 
parameters, propertys or even i make it ensurable. 

It cant be the right way, to always reset everythng on a older snapshot or? 
Why the puppetmaster "rembers" the custom_type definition and does not 
accept changes? How i handle this?

Thanks for any help

Akai

Gogs is very good, especially if you are already familiar with Github, it's
very much a clone UX wise Note that some time ago several contributors
forked Gogs to a project called Gitea (https://github.com/go-gitea/gitea)
to get more traction on PR's...etc, they later reversed this decision when
the original maintainer got back involved, but it looks as if the
maintainer has gone AWOL again and the fork is now active - this time it
looks more permanent so the project will probably continue there.
