New PXE menu entry: Deploy Image & Shutdown

[george1421]

The short answer is there is probably a way. You can set a global kernel parameter to tell the FOS engine to shutdown after its operation. But understand every operation that FOS does (FOS == customized version of linux that runs on the target computer) once it is done it will power off the system. That may not be what you want.

If you go into FOG Configuration -> FOG System Settings -> General Settings -> FOG_KERNEL_ARGS and insert shutdown=1

The fos engine should shutdown after every operation.

No, that wouldn’t work. Right now, I’m imaging 100 machines. The way we build our images is we install Windows, get it updated with drivers then we run a script before we upload the image to Fog. The script is just a host rename and domain join, something that Fog client can do but we can’t use it due to the company not wanting us to use it. If a shutdown after imaging can be done as a new menu entry, it would save me from having to register the machines in Fog and starting them from the web UI with the shutdown check box checked. I didn’t know if you could set up the menu entry to schedule a shutdown after the imaging like you can do from the web ui.

[george1421]

@psyfer9983 Maybe I didn’t explain my idea well enough.

If you were to register the machine and deploy an image. If you select the check box that says shutdown after deployment the FOG server adds the kernel parameter shutdown=1 to the instructions FOG tells FOS when booting the target computer.

So what I propose is to just force that kernel parameter for every imaging event where you PXE boot the target computer. There is no need to register the target computer, there is no need for the fog client. This command happens in the imaging stage only.

Does anyone know if or how to set “shutdown=1” via pxe menu?

[Avaryan]

Testing something. I’ll let you know in about 15 minutes if it worked.
edit: Didn’t work.

[Tom Elliott]

Is this a specific host? Are you wanting this for “every host regardless?”

[george1421]

@Tom-Elliott He wants after quick imaging to shutdown the computer, either by asking or just do it.

I thought the easiest way is with a kernel parameter.

[Junkhacker]

@george1421 that sounds the easiest to me too. since it sounds like he’s not registering them and managing them in fog anyway. the only tasks it would affect are captures and deploys.

[Tom Elliott]

@george1421 It definitely is the easiest way, but if it’s specific to “quick imaging” goto:
FOG Configuration Page->iPXE Menu Configuration->fog.deployimage
In Boot Options: add: shutdown=1

If you want it for ALL tasks (will not impact debug of course):
FOG Configuration Page->FOG Settings->General Settings->FOG_KERNEL_ARGS and add: shutdown=1

I just tried this and it did not work. Still booted to Windows after imaging.

[Tom Elliott]

@Avaryan Then something wasn’t done correctly. Did you have exactly shutdown=1? Code to validate is literally:
[[ $shutdown -eq 1 ]] && poweroff || reboot -f

[george1421]

@Avaryan Its important to not have spaces it should be one command

[george1421]

@Tom-Elliott Is there a way we can capture if the boot options field is translating into a kernel parameter for the quick image (yes I know its not called quick image any more).

[Tom Elliott]

@george1421 If they goto http://fogipaddress/fog/service/ipxe/boot.php?mac=<macofhostbooting>

You should see ‘shutdown=1’ in the list of arguments.

This is exactly what I have:

Did not work. It was an unregistered host. Haven’t tried with a registered one.

FOG 1.4.0 Revision 6069.

edit: Deploying image to a different model now. Device is registered (although that shouldn’t matter?). ETA 15 minutes.

[psyfer9983]

Right now, the only way I can get the shutdown to work is by adding the “shutdown=1” to the “FOG_KERNEL_ARGS”. It works but its set globally which is not what I’m looking for. I would like everything to function like it should on default settings (unless set when creating a task in the WebUI). I would like to just add a new entry that does the same thing as “Deploy Image” but with a shutdown after deploy. If I could pass the “shutdown=1” to “FOG_KERNEL_ARGS” via new pxe menu entry, this would be great as it would leave everything else as default settings.

FYI, I’m on version 1.3.3

This is what is currently in that PHP file, I don’t see the shutdown.

[Avaryan]

Adding shutdown=1 to the Boot Options for the deploy option does not work. Tested on 3 different devices.

[george1421]

@Avaryan I can understand why (with my limited knowledge of the inner workings of FOG) the way the quick image menu is created. The quick image menu doesn’t call the the kernel load directly but it turns around and calls boot.php again which then creates a new menu for image selection. Its possible that the kernel parameter is getting lost on this second boot.php call.

or the field value for shutdown=1 is wrong and should be written as param shutdown 1 instead to be in line with what iPXE is expecting.

[Tom Elliott]

Mind trying this?

wget -O /var/www/fog/lib/fog/bootmenu.class.php https://raw.githubusercontent.com/FOGProject/fogproject/working/packages/web/lib/fog/bootmenu.class.php

TLDR; I’m an idiot though it was meant with good intentions, please try above and let me know if it’s better.

Apparently when I was adding the API, I was trying to ensure the API was stateless and was making adjustments to elements using $_SESSION variables. The boot menu script (what I’m asking you to copy) had a few of them for something I implemented a while ago to address this very problem. Not thinking about it when making adjustments, I removed all the relevant bits and didn’t replace them. My initial thoughts were that there wasn’t anything in the boot menu requiring those SESSION elements. I’ve readded these bits and maintained the “stateless” element of the script. While I did re-add these things, my tests are currently limited to simple browser checks calling out to a rather direct url. As such, a test going into deployimage would be extremely useful from a “full” run.
