[Katello 2.3] How can I use Katello for Foreman Discovery?

Support
1

I installed Katello 2.3 on CentOS 7 with the tftp option (and a capsule in
another network that has tftp on it on CentOS 6.5).

I can provision a build from scratch in either network using either the
Katello server or its tftp capsule just fine.

I wanted to get discovery working and I noticed that even without
installing katello with any options, it had the discovered hosts menu
available, but booting a host did not lead to discovery, only an unable to
fetch tftp definition error.

So I thought I could solve this by running 'katello-installer
–foreman-plugin-discovery-install-images true'.

The run seemed to go ok, and if I look in /var/lib/tftpboot on both the
katello server or the capsule, I see the fdi-image directory has appeared
in the boot subdirectory.

However, even though it has apparently copied the image, booting a server
still does not lead to either the discovery menu or the "local" menu. It
still says unable to fetch definition.

I'm a little confused because the Foreman documentation describes how to
setup the capsule manually, but I thought Katello took care of everything
?

Is there still some setup to perform? The Katello docs do not seem very
clear on this.

I should note that I don't have Katello managing dhcp so our standalone
dhcp server was just feeding every client the following options :

next-server 10.3.3.3;
filename "pxelinux.0";

Do I need to change that to make it compatible with discovery? It was
working fine with standard katello provisioning.

I have tried rebuilding the default pxe template in the hopes that work
would, but clicking the 'Build PXE Default' button gives the following
error :

There was an error creating the PXE Default file:
katello-tftp-casuleserver.mydomain.net: ERF12-9243
[ProxyAPI::ProxyException]: Unable to create default TFTP boot menu
([RestClient::BadRequest]: 400 Bad Request) for proxy
https://katello-tftp-capsuleserver.mydomain.net:9090/tftp

I have checked and there is no firewall running on that server that would
be blocking port 9090.

Hello,

it does not matter if you use Katello or not. For Discovery, you still
need to perform the Discovery installation as described here:

http://theforeman.org/plugins/foreman_discovery/4.1/

katello-installer should work with all the commands described (and if
near future katello-installer will be "merged" into foreman-installer).
If not, you can still use manual installation instructions described
there.

You are apparently missing step 3.1.1 which needs to be done in order to
change the menu.

Check the proxy.log on the Proxy, this should work normally. Is the TFTP
module enabled? No permission issues?

Strangely enough, this just started working an hour or two later. No
further changes were made.
