Static IP assignment

Support
1

I've done some Google searches trying to find out how to do this with
Foreman. So far all I have is to figure out the MAC for the VM, and plug
that into the dhcpd.conf file. I don't think that will work well for me, as
VMWare assigns MACs when the VM is created.

Here are the contents of my Kickstart default surrounding this:

network --bootproto <%= @static ? "static" : "dhcp" %> --hostname <%= @host
%>

and here s the PXE:

append initrd=<%= @initrd %> ks=<%= foreman_url("provision")%>
ksdevice=eth0 network kssendmac ip=<%= @host.ip %> netmask=<%=
@host.subnet.mask %> gateway=<%= @host.subnet.gateway %> dns=<%=
@host.subnet.dns_primary %>

So I kick off a build and the VM completes, but it does not use the static
address. Looking at the VM templates I see it is still pulling the dhcp
address used to start the pxe process.

Use puppet to make it static. Check out the puppet-network modules on Forge.

Change this to the line in our updated templates:

https://github.com/theforeman/community-templates/blob/master/kickstart/provision.erb#L16

network --bootproto <%= @static ? "static --ip=#{@host.ip}
–netmask=#{@host.subnet.mask} --gateway=#{@host.subnet.gateway}
–nameserver=#{[@host.subnet.dns_primary,@host.subnet.dns_secondary].reject{|n|
n.blank?}.join(',')}" : "dhcp" %> --hostname <%= @host %>

Note that you'll need to ensure the subnet in Foreman
(More>Provisioning>Subnets) has the gateway, DNS server(s) etc all
configured as it'll use this data.

> @host.subnet.dns_primary %>

And change the ks= bit in the middle here to request the template
containing the static IP details:

ks=<%= foreman_url("provision")%>?static=yes

Pro tip: Install system-config-kickstart and use ksvalidator tool which
is able to find you syntax errors easily for all possible Fedora/RHEL
version out there.

Yep.

Thanks. I was just about to look into this. it might take me a minute but I
think I can make this work.

I'll update this thread on what I did to make it work.

Can I set parameters on a per host basis?

At my site, we make the IP assignment static from Debian/Ubuntu Preseed.
Kickstart probably has similar mechanisms. This way it's sort of baked in
when the instance comes up.

DHCP parameters?

Got it. I used that tool to double check my configs.

everything is working now.

Thanks all.
