Creating Task with TaskTypeManagement

cjenness

Thanks for getting back to me. I have the task type management plugin installed, and I am trying to create a task so that I can boot the wimboot installer that I set up to install windows 2012 on a specific groups that I set up as needed.

@cjenness I’m testing an idea at the moment to see if it works. I’ll get back to you. I haven’t done this exact thing just yet. But I have an idea without coding.

george1421

@george1421 Well that didn’t work out as well as I thought.

#!ipxe
set fog-ip 192.168.112.24
set fog-webroot fog
set boot-url http://${fog-ip}/${fog-webroot}
kernel bzImage32 loglevel=4 initrd=init_32.xz root=/dev/ram0 rw ramdisk_size=127000 web=192.168.112.24/fog/ consoleblank=0 rootfstype=ext4 mac=b8:ca:3a:ce:1d:1a ftp=192.168.112.24 storage=192.168.112.24:/images/dev/ storageip=192.168.112.24 osid=0 irqpoll hostname=b8ca3ace1d1a fdrive=/dev/sdb initrd http://${fog-ip}/win2012/${arch}/media/Boot/BCD BCD;initrd http://${fog-ip}/win2012/${arch}/media/Boot/boot.sdi boot.sdi
imgfetch init_32.xz
boot

It didn’t use my kernel definition and a bunch of unnecessary kernel parameters were added. We almost need to be able to deploy a fog ipxe menu. Its kind of close though.

cjenness

I have an iPXE menu configured:

“cpuid --ext 29 && set arch amd64 ||
kernel http://${fog-ip}/win2012/${arch}/wimboot
initrd http://${fog-ip}/win2012/${arch}/media/Boot/BCD BCD
initrd http://${fog-ip}/win2012/${arch}/media/Boot/boot.sdi boot.sdi
initrd http://${fog-ip}/win2012/${arch}/media/sources/boot.wim boot.wim
boot ||”

Which I can default boot, but I would like to be able to make that a task, so i can boot specific server groups.

george1421

@cjenness Yep I got that. That custom task function isn’t working as I “thought” it might. I’m still testing, but I think we might end up having to create a feature request for this action. I have see others post for something similar. Its a bit beyond the scope of what FOG was intended to do.

cjenness

Thank you for taking the time to check on this for me.

Tom Elliott

@cjenness The tasktypeedit plugin was designed to do this. It also means you may need to build your own hook to handle the more specifics.

Tom Elliott

Okay sorry thinking too much I think.

Seeing as you are getting error 500, can you provide your apache error logs?

Tom Elliott

I think the error is in the arguments.

Where is the $TaskType variable being set? (I’m guessing the 500 error will show something like:
Attempting to run non-existent method get on null at line ###).

cjenness

I’ve actually fixed the 500 error. I was missing a comma after boot.wim in the hook in OP. But I am not sure how to get the task type manager to call the hook.

cjenness

So for the hook, I have just been editing the file /var/www/fog/lib/hooks/boottask.hook.php. The only part I have edited so far are the arguments that I posted above.

Tom Elliott

Can you paste the contents of the file (or upload the hook) here please?

Tom Elliott

@cjenness Okay, if it’s the example, mark the active flag as true, that’s all you need to do.

cjenness

Here is the entire file. So I have marked the flag as true and I no longer get the http 500 error, but I am not sure how to create a task with this hook.

@cjenness In the FOG web GUI click on one of your hosts or groups, then click ‘Basic tasks’ on the left and ‘Advanced’ to show all the tasks available. Do you see “BootTask” here?

Tom Elliott

Well the “BootTask” would be whatever task type was created. The “boottask” is just the hook that makes that hook operate.

cjenness

Thank you guys for your help. So my question now is how do I tell the task type editor to use the hook that I just created?

cjenness

Nevermind, I figured it out. You have to title your new task the name (trusty-install) in this portion.

$TaskType = self::getClass(‘TaskType’)
->set(‘name’, ‘trusty-install’)
->load(‘name’);
if (!$TaskType->isValid()) {
return;

Sorry to resurrect an old thread, but this just came up as something we need to be able to do (assign a custom boot task to hosts/groups of hosts). My understanding of the discussion below is that I should

Enable plugins (Fog Configuration->Fog Settings->Plugin System->PluginSys Enabled)
Activate the tasktypeedit plugin
Edit lib/hooks/boottask.hook.php, setting public $active = true;

Then I should be able to visit a host page -> Basic Tasks -> Advanced Tasks and see ‘trusty-install’ as one of the options, but I don’t see any change to the menu. Have I missed something in the configuration?

Sebastian Roth

@ianabc Have not had any time to look into this. Haven’t used that plugin in a long time and need to fiddle with it before I can give you any answer. Might be on the weekend.
