Munki’s command-line tools have the ability to extract icons for various items in your Munki repo, as you saw in Adding an item to your Munki repo
But you can also use MunkiAdmin to extract icons for items in your repo that you may have populated using AutoPkg.
In MunkiAdmin, click on File and then select Batch Extract Icons…
You’ll see that MunkiAdmin selects only the items that don’t already have icons (we imported Firefox manually earlier, and so were able to extract the icon for it during the manual munkiimport process). Click Extract to try to extract icons from each item.
Some items (like the munkitools ones) don’t have icons, so there are no icons to be extracted. Other items (like AdobeFlashPlayer) may have multiple icons, so one can’t automatically be assigned.
Afterwards, you should see items (instead of package placeholders) for the items that MunkiAdmin was able to successfully extract icons for.
If you want to get the icon for AdobeFlashPlayer, you can right-click it, select Icon and then Create New Icon for Name “AdobeFlashPlayer”
Click Extract
Pick whichever icon you like best out of the extracted icons.
Click Save
Then, click Save again.
