Augeas: Duplicate declaration

[Reinaldo Lima]

Hi Everyone,

I'm trying to write a class that put some entries in "/etc/hosts" file as follow below:

class hosts {

        $netentry = {

                host01 => { iphost => '192.168.10.1', hostName => host01 },

                host02 => { iphost => '192.168.10.2', hostName => host02 },

                host03 => { iphost => '192.168.10.3', hostName => host03 },

        }

        define hostsinclude ($entry) {

               augeas { "hosts_include":

                       incl => "/etc/hosts",

                       lens => "Hosts.lns",

                       changes => [

                               "set /files/etc/hosts/01/ipaddr $entry[$name]['iphost']",

                               "set /files/etc/hosts/01/canonical$entry[$name]['hostName']",

                               ],

                       onlyif => "match */ipaddr[ . = $entry[$name]['iphost'] ] size == 0"

               }

        }

        hostsinclude { [

                'host01',

                'host02',

                'host03'

                ]:

                entry => $netentry

        }

}

and, when puppet compiles the manifest, I get the following error: 

err: Could not retrieve catalog from remote server: Error 400 on SERVER: Duplicate declaration: Augeas[hosts_include] is already declared in file /puppet/environments/production/modules/checklist/manifests/hosts.pp at line 10; cannot redeclare at /puppet/environments/production/modules/checklist/manifests/hosts.pp:29 on node

Someone can help me?

Thanks

Your augeas resource is always called hosts_include which is why it's doing that.  Try including the entry[name] in that resource name.

another option to use create_resources('hostinclude',$netentry)

With "create_resources" the error is:

Invalid parameter hostName on node

And including the entry[name] in the resource name:

Resource title must be a String, not Hash

 

=(

[Andrey Kozichev]

ah, right you are supplying entire hash in your defined resource. Missed it.

If your defined resource would accept: name, iphost and hostname - then you can use create_resources to define all 3 entry.

Sorry, didn't realize it was a hash of hashes.  You just need the augeas resource to have a unique name - entry[$name][hostname] or ipaddress should work.

IE:

define a_thing {

  augeas { 'host_entry': }

}

a_thing { 'a': }

a_thing { 'b': }

Will generate an error like you are seeing.

define a_thing {

  augeas { "host_entry_${name}": }

}

a_thing {'a': }

a_thing {'b': }

Will not.

Almost there! =)

My only change was '"host_entry_${name}" :' like you suggested,

everything else in the code is like my first post, and the error now is:

"Could not evaluate: uninitialized constant Augeas::NO_MODL_AUTOLOAD"

By the way, thank you so much for the help, this topic made me learn a lot about puppet =)
