[Puppet Users] augeas

[Stanislas LEVEAU]

Hello

I use augeas to replace a value in a config file:

example (this example is good) :

/etc/ssh/sshd_config file

LogLevel INFO


class ssh::redhat {
augeas { "sshd_config":
  context => "/files/etc/ssh/sshd_config",
  changes => [
"set LogLevel VERBOSE",
  ],
  notify => Service["sshd"],
}

This configuration is good

but how do when the file is written like this:

parameter = value (with =)


/etc/webmin/config file

lang = us


class webmin::redhat {
augeas { "config":
  context => "/files/etc/webmin/config",
  changes => [
"set "lang =" fr]",
  ],
}
}

this configuration is not good, did you have an idea?
regards

[Puppet Users] High Availability of Puppet server for separate geographical location

[shyam sundar Keshari]

Hi Team,

I have to configure puppet server in Primary-Secondary mode for 2
distributed location .

Site A is already running 1 Puppet server .Now I need to configure
another puppet secondary server at site B ,so that

all client at location B ,only connect to that server .And site A
puppet client only connect to site A .

But mine requirement is of that suppose site A server goes down then
Site B server handle all client request and

[Puppet Users] rspec-puppet testing with puppet $::settings

[Simon Piette]

Hi all,

Let's say I have this in a manifest:

file { "${::settings::vardir}/files":
  ensure => directory
}

And I want to test it in the catalog using:

it { should create_file('/var/lib/puppet/files') }

It won't work because an mktemp directory is made for vardir for each
catalogue. The catalogue will containt a
File[/tmp/d20130429-26229-3glbki/files] reference.

Curiously, in the "it" block, Puppet[:ssldir] is expanded to /dev/null/ssl
and Puppet[:vardir] to /dev/null (consequently).

Is it possible to access the Puppet[:vardir] from the
{Class,Define,Host}ExampleGroup?
Or any other $::settings variables?

Other ways would be to include a puppet.conf to inject settings, or as we
already do with facts, inject :settings at the beginning of the describe
block.

Any solution for testing variables that depends on settings will be welcome.

Thanks,

[Puppet Users] What's my syntax problem: "Could not match 'c:/tmp' " ?

[Larry Fast]

I assume I have a syntax problem of some kind. I created a class file and 
puppet complains on line 4.  If I remove that block of code it complains 
about the next block. What silly little mistake have I made?  The error 
reported for the code example below is:

Could not match ‘george’, at 
/etc/puppet/environments/dev22/modules/custom_facts/manifests/virtuals.pp:4

class custom_facts::virtuals() {
  
  $tmp1 = $operatingsystem ? {
/hello/   => ‘george’,
/windows/ => 'C:/tmp',
default  => ‘/tmp’,
  }
  @file { 'tmp':
   ensure => directory,
   path => "$tmp1",
  }

Re: [Puppet Users] Help me with overriding define resource

John, you're such a tease ;-)

While I mostly agree with the points you're making (as so often), I feel
that this thread is incomplete without giving an example of the
syntactically correct implementation of the original idea.

Note that this approach has a number of issues and should usually be
avoided. Use at your own peril.

class composition {
  include base_class

  // wrong:
  //Definition['TestCase'] {
  // right:
  Definition<| title == 'TestCase' |> {
var => '/tmp/bar',
  }
}

[Puppet Users] Re: Sharing data between nodes with hiera

[Luca Gioppo]

I'm new of hiera and I was thinking that it was possible to declare hiera 
variables just linked to nodes or classes.

Indeed the option of getting the data using the hiera() function allows for 
a common.yaml file to host the global information and thus will follow your 
suggestion on having classes that build the needed configuration.

Uhm, what? Why? Why is there a git repository for your transient puppet
reports?

You're reinventing the wheel I think (although your's a bit square-ish ;)

Doesn't the dashboard usually consume the report as generated by the
agent? Therefor, isn't what you want a way to transfer that very report
from the agents to the dashboard? I vaguely remember an issue with
masterless not generating reports, but I may misremember this one.

How so?

Anyway, first debugging steps:

1. Does the error disappear when you set $lookup = 'foo'

2. Does the error disapper when you change the variable name, say $foo =
hiera(...)

3. Does the error disappear when you comment out the other declarations
in the class body?

Thanks,
Felix

Re: [Puppet Users] Microsoft dotNet Framework 4.0 (.net, .netfx, dotnetfx)

In order to resolve this limitation, I wrote a PowerShell script to install

perform a silent install of 'dotNetFx40_Full_x86_x64.exe'.

[Puppet Users] Puppet Windows - Mapped Network Drive and Service Account

[Kevin D]

On Windows 2008 R2 SP1, after joining to the domain, there is an issue with 
a mapped network drive when Puppet agent runs by the "LOCAL SYSTEM" service 
account.

Using dependency chaining, a near the beginning module is 
"map-networkdrivez". The module execs a batch file that if Z:\ does not 
exist (not already mapped), maps Z:\ to a Windows 2008 R2 SP1 file server 
with a hidden share "data$". The file server is configured for anonymous to 
allow share access (with the appropriate NTFS and Share permissions).

By default, when the puppet agent runs as the service, the associated 
service account is "local system". On first run, the batch file 
appropriately maps the drive and the modules have access to the resources 
of the mapped network drive.

Once a module executes that joins the computer to the domain and restarts 
the computer, subsequent puppet runs fail because of a failed resource 
dependency on Z:\:

 Could not evaluate. Could not retrieve information from environment 
production source(s) file:/z:/Install-Exe.ps1

I setup a SysInternal's Process Monitor trace during a puppet run:

Path   = "\\;LanmanRedirector\;Z:03e7\10.202.1.27\Data$\"
Result = "ACCESS DENIED".

I verified the same result using psexec to open a cmd prompt under the 
"LOCAL SYSTEM" account by opening a CMD with administrative privileges, 
running "psexec -hsi cmd" and navigating to "z:"

Access is denied.

If using the local administrator account I open a cmd prompt  run 
"C:\Program Files(x86)\Puppet Labs\Puppet\bin\puppet agent -t" all the 
modules will execute successfully.
If I change the Puppet service account from "LOCAL SYSTEM" to 
"testwindows004\Administrator" all the modules will execute successfully.

Has anyone else seen this behavior? Any thoughts on how to overcome this 
issue?

Yes, absolutely.  This sort of thing is one of hiera's core use cases.  Did 
you have specific concerns about it?

 

> Also passing this data to standard modules in a proper way?
>

I don't understand what you're asking.  In particular, I don't know what 
"standard modules" means to you.  Generally speaking, however, there are 
three key ways by which classes (in modules) can obtain data to work with:

   1. The data can be hard-coded into the class
   2. The data can be drawn from class variables (including a class's own 
   parameters)
   3. The data can be retrieved or computed via a function

If the main source of the data is hiera, then ultimately option 3 is how 
the data get into Puppet (using the hiera() function explicitly or else 
relying on automated class parameter binding).  The main decision you have 
here is whether option 3 will be used everywhere the data in question are 
needed, or whether it will be used once to set class variables (maybe 
parameters) of one or more classes, and then other classes will obtain it 
via those class variables.

You should consider creating a class purposed with stewardship of the 
data.  It would load them from hiera either via explicit hiera() calls (my 
preference) or via automated binding to class parameters (Puppet 3+ only).  
Other classes that need the data would then reference the steward class's 
class variables to get them.  Place the steward class in an appropriate 
module and give it an appropriate name for the scope of the data it handles.

[Puppet Users] Re: hiera malformed format string - %S

[Luca Gioppo]

OK, solved!!
The problem was the TAV character that notepad++ added to the hash.
It seems that something in ruby does not like it (do not know ruby so...) 

If this is the correct behaviour there should be somewhere in the docs a 
warning for DO NOT USE TABS IN YAML file as it took quite asome time to 
find out.

If is not a correct behaviour than is a bug :P

I think a key thing you have missed is that when you install a module by 
hand, you are meant to remove the leading "-" segment of its 
directory name.  Use of such prefixes helps avoid accidentally clobbering 
one module's contents with those of a distinct yet like-named module's, but 
you cannot actually have two different modules with the same name installed 
(and functional) at the same time.

There are basically two approaches:

   1. The master knows at all times which nodes are supposed to be 
   production servers.  This would involve an exhaustive list of the 
   production servers in a Puppet manifest or in a data file read by the 
   master.  In this case, you would probably just build the file via a 
   template and apply it as a normal File resource.  No stored configs are 
   needed for this.
   2. What I think you're saying, though, is that you want Puppet to 
   dynamically recognize nodes based on their self-declared environment (if 
   the master were choosing the environment rather than the agent, then you 
   would have case 1).  The most natural way to handle this situation is via 
   exported resources (which requires stored configs).

For case 2, the key thing to remember is that each production server must 
declare and export a distinct resource that describes its own node-specific 
data.  That's not the whole file, but rather just a piece of one.  The 
Concat add-in module is perfect for this sort of thing.  You might use it 
like so:

# This class must be included on production servers
# (and not on other nodes).
class prod::server {
  # Export a line of the production server list
  @@concat::fragment { "prodserver-${hostname}":
target => '/root/production.servers',
content => "${hostname}\n"
  }
}

# Nodes that should have the server list declare this class;
# they may be production servers, but do not need to be.
class prod::serverlist {

  # The target file
  concat { '/root/production.servers':
owner => 'root',
group => 'root',
mode => '0644'
  }

  # Import all the fragments:
  Concat::Fragment<<| target == '/root/production.servers' |>>
}


The final piece, then, is to ensure that class 'prod::server' gets declared 
on all the production servers, and only those.  If you're going to use the 
$environment variable to control this, then that means putting a 
conditional statement such as this one somewhere that that is evaluated for 
every node:

if $environment == 'production' {
  include 'prod::server'
}

That could go in a shared base node or in a common class that all nodes 
declare.

One agent is associated with one master.  It cannot talk to two.  In 
principle, you could run two independent agents on the same node, talking 
to different masters, but this is a very bad idea.

Impossible.  Your application is dependent on the underlying basic system 
configuration, so no matter what you do you cannot keep them fully 
separated.  You could draw an arbitrary line somewhere to partition your 
configured resources between two masters, but all that really would do is 
make things harder for you by preventing you from expressing relationships 
between resources assigned to different partitions.

There are a number of things you can do to organize resources within a 
single master.  The most basic is to use modules appropriately.  If you 
want physical separation of manifests on your master, then you can add one 
or more directories to your module path so that you can put your 
application modules in a separate tree from your base-system modules.  
There may be other things you can do to address specific concerns.

[Puppet Users] checking puppet run status of node A during puppet run of node B

[Schofield]

I have some middleware where the successful configuration of node B is 
dependent on the successful configuration of node A.  Node B must pull 
additional information from node A during its configuration.  Is there any 
built in functionality in puppet for checking the completion status of 
other nodes?  Right now my intent is to write a custom function to query 
the puppetdb which is storing reports.  I want to make sure I am not 
missing some other elegant solution in puppet that already does this.

and the command
hiera -c /etc/puppet/environments/production/hiera.yaml greg

Re: [Puppet Users] Re: Design pattern for exported resources from EC2 autoscaled instances

[Keith Burdis]

You should be able to cluster Tomcat without using multicast by having a
static members list with TCP pings to check the cluster nodes. You could of
course use exported resources to create the static members list.

Not sure about Glassfish but I'd expect it to be possible to do something
similar as Weblogic allows the use of unicast instead of multicast for
static clusters.

[Puppet Users] Sharing data between nodes with hiera

[Luca Gioppo]

I have this, I think common, situation:

- NodeDB VM with MySQL
- NodeApp VM with an application that uses the MySQL DB

Obivuously both needs to have information on the DB (like user, DB name, 
etc.)
Since DB will be created in the NodeDB by the MySQL module from puppetlabs 
and the app will just connect to the DB and do its work, but need to set 
the configuration parameters.

Now ...
since App can be installed at any moments at a precise point in time will 
have to modify the NodeDB definition adding the DB for app and than 
create/modify the NodeApp to configure app.

Can I write down the DB info just once in hiera and refer to these common 
data from the two nodes? Also passing this data to standard modules in a 
proper way?

This could become handy when I'll have to add a third node, let's say 
NodeBI that needs to access the app DB for business intelligence reasons, 
so I'll have to configure a new node with the same DB data.

I think that there is the need to access a much higher scope information, 
but haven't found any clear (at least for me) documentation on this.
Thanks
Luca
