Add second NIC as fixed IP

Support
#1

Hi,

I have been working with Foreman for about 2 months now but I reached a
roadblock and don't know how to continue. Here is the situation:

I am trying to provision a static IP on a physical computer that has two
NIC cards. I can set the first NIC as fixed through the kickstart using the
following entry:

network --bootproto static --ip=<%= @host.ip %> --netmask=<%=
@host.subnet.mask %> --gateway=<%= @host.subnet.gateway %> --nameserver=<%=
@host.subnet.dns_primary %> --hostname <%= @host %>

This will setup the IP as it is defined in the GUI of Foreman.

As for the second NIC, I want it to be configured through puppet, but so
far I have not found a way to do so. I tried using the definitions from
razorsedge ( https://forge.puppetlabs.com/razorsedge/network ) but there
are no variables that are added to foreman once I update foreman with the
latest puppet modules. FYI, in this manifest the NIC card configurations
are set as defined and the author recommends adding a simple node
configuration as follows:

node default {
include network
network::if::static { "eth1":
ipaddress => "1.2.3.248",
netmask => "255.255.255.128",
ensure => "up",
}
include groups
}

Problem is, I don't know how to include these statements in the foreman gui. I read about using External nodes, but the instructions on how to use it are not clear to me. I also tried looking for youtube videos to see if somebody was using external nodes but couldnt' find anything.

This might not be the best way to add a second static NIC, so I am open to alternatives to complete this task.

Thanks for your help.

As long as your puppet module provides Parametrized Classes, you can
import them into Foreman and then assign them to hosts giving them
required parameters.

Read the manual:

razorsedge/puppet-network <https://github.com/razorsedge/puppet-network> is
focused on using resource definitions more than parametrized classes. I
think OP's best bet might be to write a wrapper class to import into
Foreman.

I use a similar hack-ish tactic to use params to convert from dhcp to
static post provision…

$use_gateway = $::default_gateway_interface ? {
  $udnet::interface =&gt; $::default_gateway,
  default           =&gt; undef,
}
case $udnet::ip_method {
  /(?i:static)/: {
    network::if::static { $udnet::interface:
      ensure     =&gt; &#39;up&#39;,
      ipaddress  =&gt; inline_template(&quot;&lt;%=

scope.lookupvar('::ipaddress_${udnet::interface}') %>"),
netmask => inline_template("<%=
scope.lookupvar('::netmask_${udnet::interface}') %>"),
gateway => $use_gateway,
macaddress => inline_template("<%=
scope.lookupvar('::macaddress_${udnet::interface}') %>"),
}
}
/(?i:dynamic|dhcp)/: {
network::if::dynamic { $udnet::interface:
ensure => 'up',
}
}

I've also found that doing such host specific things with an arbitrary
class can be quite difficult. As a result, I've created a "hosts" class
which is designed to contain manifests for specific hosts. I often end up
using these only for host specific resource definitions like firewall
rules, nagios monitors, or apache vhosts.
