Array Iteration for Community Edition of Puppet(3.8)

[Joe]

Hi All

Puppet v3.8.7 community on Ubuntu 14 LTS

I have been attempting to write a class to use the "file_line" type reference from the stdlib library to add multiple lines to a file if these lines are not present.
I was attempting to do this with iteration using the each function and tried with static and Hiera arrays. After a few hours of failure I came across the docs for Puppet Enterprise that say this iteration capability was introduced in Puppet 4.

It looks like this, testdefs is an array in Hiera defined in the nodes yaml config

 each($testdefs) |$hline| {
   file_line { 'Append a line to /etc/testfile':
      ensure => present,
      line      => "$hline",
       path    => '/etc/testfile',
    }
}

To be clear I am trying to..
iterate through a Hiera array
pass each array member to the file_line type
append this member to a file if it does not exist. 

Is there a way to do this with Puppet 3.x or should I just make a static class with multiple file_line types?

Thanks

Puppet 3 is now dead, upgrade to Puppet 4 - it's free - and you too can enjoy

While understandable, that's something of an irritating answer-- It underlies a problem I've felt puppet has had since the 1.x days-- Any feature you're using can stop working with little warning, unless you follow the puppetlabs blogs closely.

Newer changes aren't quite as drastic as banning hyphens from a class name, but it can still be a major pain when you have a bunch of puppet code that used to work.  :)

It also does a nice job of completely ignoring the user's question.

@Joe:  The iteration feature is available in Puppet 3.7.x and later, but you need to enable the "future parser"-- which is also the first step in upgrading smoothly to puppet 4.x.

This isn't a case of something that stopped working, the feature is new.

Just blindly enabling future parser, especially on older 3.x releases
can actively cause pretty bad side effects, unexpected changes to nodes etc

First time I did it I had to reinstall the machine in question, so perhaps
not the best of advise either :)

Hello Guys thanks for the replies..

Apologies for the top posting here.. the reply to post only includes my text. I am using the "puppetlabs-release-pc1-trusty.deb" apt source from puppet labs and the latest version is 3.8.7 as seen below. I am also using the puppetmaster-passenger package from the same repo. R.I Pienaarr said to use version 4 however I do not see puppetmaster 4 packages available.

puppetmaster:
  Installed: (none)
  Candidate: 3.8.7-1puppetlabs1
  Version table:
     3.8.7-1puppetlabs1 0
        500 http://apt.puppetlabs.com/ trusty/main amd64 Packages
     3.8.6-1puppetlabs1 0
        500 http://apt.puppetlabs.com/ trusty/main amd64 Packages


Am I missing something? How can I install the Puppetmaster 4 and Puppetmaster-passenger 4 packages on ubuntu server via repository?

Thanks again

[R.I.Pienaar]

You'll have to read about upgrading, its quite the undertaking and the
process is designed so people dont accidentally update and then end up
with inoperable CM systems.

Best start with the Puppet 4 upgrade docs and release notes etc, also
some pretty good talks at recent Puppetconf about updating

Thanks R.I.

So iteration works with 3.8x with future parser. I am going to avoid 4 until Debian builds it into their repositories.

So iteration works but not with file_line..

Here is the code.

hiera array
mod1::testdefs:
  - 'hello'
  - 'there'
  - 'friends'
##mod1  init.pp

each($testdefs) |$hline| {
   file_line { 'Append a line to /etc/testfile':
      ensure => present,
      line      => $hline,
       path    => '/etc/testfile',
    }
}

##error is this
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: File_line[Append a line to /etc/testfile] is already declared in file /etc/puppet/environments/test/modules/mod1/manifests/init.pp:48; cannot redeclare at /etc/puppet/environments/test/modules/mod1/manifests/init.pp:48

I tried putting the loop in the file_line type but that throws another error since it is not acceptable to file_line.

Is there any way around this that you guys are aware of?

Thanks

Got it guys, the issue was with the file_line declaration as evidenced by the error. I made the declaration change with the variable and it worked.

Thanks all for the help.

Be aware that all vendor support for Puppet 3 ended at the end of 2016, and Puppet provides their own packages (puppet-agent and puppetserver in PC1 replace the older puppet/puppetmaster combo) so you don't have to wait on Debian. While you should plan your upgrade with care, the lack of any support should be a motivating factor to start planning immediately instead of waiting on a third party who isn't negatively affected by waiting, like you are.

Thanks for the heads up Rob. I am using this repository from puppetlabs.
puppetlabs-release-pc1-trusty.deb

In this repository the latest is 3.8.7. You mentioned puppet releases puppet-agent and puppetserver version 4 in PC1. Even when I manually look in the repo there is no trace of puppetmaster 4 or puppet-agent 4. I manually browsed the main and PC1 package lists and I don't see the puppetmaster 4 or puppet-agent 4, probably I am missing something. Do you know where I can find the packages?

On docs.puppet.com I find the links for upgrading from 3 to 4, is this the recommended material for upgrading?

• Upgrade: From Puppet 3.x
  • Get upgrade-ready
  • Upgrade Puppet Server and PuppetDB
  • Upgrade 3.x agents
  • Updating 3.x manifests for Puppet 4.x
  • Post-upgrade clean-up

Thanks again

That looks like it. https://docs.puppet.com/puppet/4.8/install_linux.html#for-apt-based-systems Specifically handles installation for apt; I'm a die hard rpm fan so I can't help beyond that link, sorry.

Yes I am also an RPM man and only chose this route because I thought the correct path was puppet with passenger, but reading the docs now I see that puppet-passenger is not the path going forward and puppetserver is the way now. I installed puppetserver 2.7.2-1puppetlabs1. Is this "puppet 4"?

I am a few days into puppet and so I am a bit confused.

Thanks again

Yes, puppetserver 1 was included with later versions of puppet Enterprise 3.x; puppetserver 2 is included with open source and enterprise editions of puppet 4. I think puppetserver 2.7.2 would align with Puppet 4.7.2 but you'd want to double check that for the exact minor version.

All good guys, thanks. Puppetserver 2.7.2-1 installed and clients working.
