If you compare the behavior of the Exec type to the Host type, Exec is more
flexible because it has a command => parameter. This is useful if you would
like to create multiple Execs with different namevars, but similar commands.
When working with the Host type, I've found that the namevar becomes the
"canonical_hostname", and there is no way to override this. Here's a specific
example of when having multiple Host resources with the same namevar would be
useful:
<pre>
@@host { "$fqdn":
host_aliases => $hostname,
ip => $private_ip_interface,
tag => "normal_server_private-${region}",
}
@@host { "${fqdn}":
host_aliases => $hostname,
ip => $public_ip_interface,
tag => "normal_server_public-${region}",
}
</pre>
Since both exported resources have the same namevar, I receive a parse error:
<pre>Error 400 on SERVER: Duplicate definition: Host[puppet.dev.server.com] is
already defined in file /etc/puppet/modules/hosts/manifests/collect.pp at line
33; cannot redefine at /etc/puppet/modules/hosts/manifests/collect.pp:43 on
node puppet.dev.server.com</pre>
However, If the Host type had the ability to pass a canonical hostname (fqdn)
argument, I could do:
<pre>
@@host { "${fqdn}-private":
canonical_hostname => $fqdn
host_aliases => $hostname,
ip => $private_ip_interface,
tag => "normal_server_private-${region}",
}
@@host { "${fqdn}-public":
canonical_hostname => $fqdn
host_aliases => $hostname,
ip => $public_ip_interface,
tag => "normal_server_public-${region}",
}
</pre>
