Hello,
In foreman you can define subnets, and define DNS servers for them. I want
to use these entries to configure the network in the hosts, using puppet
classes.
Currently i have my own custom class (which uses razoredge/network) to
reconfigure my network to bond both interfaces, and then declare it's IP
etc on the bond:
network::bond::static { 'bond0':
ensure => 'up',
ipaddress => "$::ipaddress",
peerdns => true,
dns1 => '172.16.1.102',
dns2 => '172.16.1.112',
gateway => '172.16.1.10',
domain => 'domain.local',
netmask => '255.255.255.0',
bonding_opts => 'mode=active-backup miimon=100'
}
network::bond::slave { 'em1':
ethtool_opts => 'autoneg off speed 1000 duplex full',
macaddress => "$::macaddress_em1",
master => 'bond0',
}
network::bond::slave { 'p1p1':
ethtool_opts => 'autoneg off speed 1000 duplex full',
macaddress => "$::macaddress_p1p1",
master => 'bond0',
}
However, as you can see I'm currently hard coding DNS servers and gateway.
I want to use the settings for the 172.16.1.0/24 subnet. How do I do this?
On a general note: Is there a list somewhere of all $:: variables I can use?

In 1.3 you can use ERB in your parameters - so for example, you can create
a parameter like:
"mysubnet" => "<%= @host.subnet.network %>/<%= @host.subnet.cidr %>"

Click the YAML button on a Host page to see all the data that's being sent
to Puppet for that Host.

Another option, since 1.3, its possible to use erb within foreman
parameters…
e.g.
add a new parameter somewhere (domain etc) and in the value for you could
do:
<%= "#{host.subnet.network}" %>
in theory, you could go further and even use host.subnet.attributes and
pass it to create_resource, but you might need to turn off safe rendering
for that.

Click the YAML button on a Host page to see all the data that’s being sent

Thanks. I'm going to try that out.
On a related note. Is it possible to define multiple subnets for a host in
foreman?

You can add multiple interfaces to a host in Foreman with different
subnets, IP addresses and names which are available then as
@host.interfaces in templates.
Check
TemplateWriting - Foreman for
some notes on using it. I think you may need to disable render_safemode
for access to these variables.
