Script to install programs from Cached DMG in Jamf waiting room

[ChristopherGlov]

Hello Everyone. My name is Chris. I made this handy script that mounts cached DMGs and installs the contents silently for users. I know this isn't a big deal or anything but I wanted to contribute something for those learning to script for bash or may be in a packaging position for JSS for the first time and need something to reference to help them along. Please feel free to use this to your hearts content. The example below is for JRE10

-Cheers

#!/bin/bash

@TheBeastie With your example you can just upload the PKG that is inside the DMG. Deploy the PKG with a policy and you are all set.

This may be helpful as well. You can deploy a policy with "Install Cached" which will do exactly what your script is doing. Additionally you can select "Install Cached Packages" from the Maintenance payload which will install all items in the Waiting Room.

but doesnt that only work with dmgs that only have .pkgs? what about .exec and .app files?

[amit_vasani]

@TheBeastie Well Jamf Admin supports PKGs, DMGs, and MPKGs (with the exception of .app that is an OS Installer). So if you do have an .app that you would like to deploy, you would use composer to build a DMG/PKG. Then cache it with a policy.

Install Cached Packges will install any "Package" (DMG/PKG) in the Waiting Room folder.

In the specific script example posted by @TheBeastie they are installing the embedded JavaAppletPlugin.pkg inside the Java Plug-in installer app bundle, something Java has been doing now for a while.
In my case, I simply drill into the Contents folder of the Java app bundle and extract the pkg and upload that directly to Jamf Admin. It doesn't need to remain inside that location and installed from there to work in my experience, so there really shouldn't be a need to do anything special with the Java plug-in install other than getting that embedded pkg from the app and using that.

I guess one instance where my script would come in handy is VPN installation and configuration. Im doing the below for this.

@TheBeastie Do you have a github? I have one that is currently being redesigned. But I have over 800 scripts for Mac, Linux/BSD and JAMF.

[ChristopherGlov]

I actually dont. I was thinking about putting some of my work in a github. I do a lot of stuff for OSX and FreeBSD and Windows. May be worth my while to put my work there since I have over 2000 scripts that I tend to forget I even have.

[Snickasaurus]

Recently deleted all the info off of mine. Starting over as it was a bad design in the first place. Going to take weeks to get all of my scripts back in there. I believe it's worth it though. Especially if you're a good scripter and don't mind sharing. And it definitely seems you're proud of your work and like sharing.

@amit.vasani , I've simply zipped any other supporting files for the installation and cached the zip file into Waiting Room folder. Then I used the simple unzip -o "source/zipfile" -d "destination" command to unpack the contents and used the files for the commands in the script.

Uploading the zip file to Jamf Admin is fine. It just recognises it as unknown format.

Just here to say that this was helpful. Thank you.
