Creating Task with TaskTypeManagement

[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

1. Enable plugins (Fog Configuration->Fog Settings->Plugin System->PluginSys Enabled)
2. Activate the tasktypeedit plugin
3. 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.

[Sebastian Roth]

@ianabc Had a bit more time to look into this now. You have missed one important point here. You need to manually create a new TaskType (web UI -> main menu -> TaskTypes -> Create New Task Type) and name that trusty-install - exactly the name of the task that is used in lib/hooks/boottask.hook.php (line 73). As soon as you’ve created this task type you should see it in Host -> Basic Tasks (or Host -> Basic Tasks -> Advanced Tasks if you’ve checked the “Is Advanced” checkbox when creating it!).

Now you can schedule this task type for any client or group and when it boots up it uses the arguments you set in lib/hooks/boottask.hook.php (line 83 to 93). But only if the names match. So if you name your new task bababoo you need to have that in your lib/hooks/boottask.hook.php line 73 as well.
