Custom Schemas For Application Configuration Profiles

[noahdowd]

I created a couple of custom schemas in JSON for this new feature. Just cause I'm excited about it! I learned JSON schemas today to do this, so they might be a little basic but maybe someone will find them useful.
Enterprise Connect:

I absolutely love this!

You're doing exactly as I'd hoped when I first learned of this feature internally, which is the community would help build manifests and share them with others. You've also given some very interesting examples of what these manifests can do too.

We're planning to provide a lot more next week to help the Jamf community discover and use management manifests. Stay tuned.

And thanks for sharing!

Hey @noahdowd, thanks for posting these custom schemas! These are very cool, and illustrate how useful this new feature can be in the product. Of course, thanks also go to Jamf for adding the feature in in the first place.

But I need to ask, given the complexity of the last schema you just posted above on Firefox, are you using some kind of tool to build these, or are you hand crafting them? I ask because after seeing some of the ones you posted earlier, I began looking into it and starting working on one for NoMAD, which, once I feel it's done I'll post here. Maybe this thread can serve as an initial placeholder for new Custom Application schemas until there's a better repository for them. But I've been making the one I'm working on by hand, and I gotta say, it's a TON of work! Plus, since I'm a total noob on JSON, I have to keep checking my work through an online JSON validator, which tells me if I've formatted something wrong and can correct it.

So, how are you making these? I'd love to find some way to speed up the process if possible. If there isn't one, that's fine, but its just good for anyone else coming here to note that these aren't exactly easy to create if you aren't that familiar with their structure at first.

[noahdowd]

Haha nope all by hand! Just BBEdit and this JSON schema validator.
I'm adding things like titles, descriptions, and enums as I learn about them. A tool would be great!

[mm2270]

Ah, ok. Good to know. :) I'm also using BBEdit for my tooling, though I was using a different online JSON validator. Thanks for the link to that one. Good to have options!

In looking at your most recent one, you gave me some ideas on how to better structure the data so I can sort of "group" related items together in more logical sections. I wasn't happy about how each setting was on it's own line and taking up so much space in the final UI. I'd like to put related items, such as naming the menu items for example, in a grouping so they make more sense. I might try to copy off of what you've done. Again, thanks for posting these!

[jhuls]

So could someone explain to those of us who might be considered at times to be slow behind the wheel(so to speak anyways) what is this JSON schema thing you speak of? What does this accomplish?

[mm2270]

@jhuls Valid question. I'm not a JSON person, so I'm only just learning about it. JSON stands for JavaScript Object Notation. It's an open standard for data exchange. But more importantly, what Jamf added in Jamf Pro version 10.19 is a way for us to create JSON schemas that can be used with their relatively new Application & Custom Settings payload.

Once configured, instead of using just the couple of ones that Jamf provides out of the box win their own repository for their own products (Jamf Connect, etc.) and Microsoft Office & AutoUpdate, you can choose Custom Schema now from the list.

Once you do that, you get a few tabs that show up, one called "Schema" that let's you paste in custom JSON formatted text, that can define the options available in a nice GUI way to set up preferences. This is basically another way of creating a Config Profile for something like a 3rd party application. We've always been able to upload a crafted plist with the values we need, and have Jamf Pro read it in, but it's not easily editable in that format, whereas with the new JSON schema, we can add/remove keys, make changes to the values on the fly and so on, without needing to edit a plist file and re-upload it.

Here are some screenshots that show how the one I'm working on looks once it's imported and you click on the "Properties" tab. This is for the application NoMAD.

..and there's more that I'm not showing here, like all the custom icon paths and so on, just because it's too many images. Basically, all the options that are normally in a plist file with keys and values will show up as GUI objects that you can set, and then when saved, the Config Profile is written out so it applies whatever settings you've chosen/set.

Another cool thing with this is that you have a way of adding/removing keys right in the UI. So for example, let's say you don't care about setting the certificate options, specifically the "Get Certificate Automatically" and "Exportable Private Key" items. You can just click the top Add/Remove Properties button and then uncheck those items from the list and they will get removed from both the UI and the final Config Profile.

Pretty cool!

So hopefully that helps to explain a little of why we're discussing this. Again, this is new in 10.19. I'm testing it out under the 10.20 beta because my Jamf cloud instance isn't scheduled to be upgraded until this weekend I believe.

[jhuls]

@mm2270 Thanks a ton for that explanation. We're still on 10.17.1 ourselves but hoping to upgrade in the next couple weeks. This looks like a practical feature to definitely look forward to.

[mthakur]

@mm2270 I agree this is a significant step forward, but it appears to shift the complexity from writing plist files to ... writing JSON files ... with a text editor ... by Jamf admins ... at end user organizations.

What would be ideal, though, is if third party app developers themselves created these JSON files and maintained them over time, and perhaps Jamf Pro could import them.

Admittedly, this approach would open up security concerns (which potentially could be fixed in part by signing the JSON files), but it would have the huge advantage of placing the burden squarely where it belongs, namely on the app developers and MDM providers themselves.

Edited to add: See this link for a fine example of a third party app developer — Microsoft — doing exactly that:
Simplifying Microsoft Edge configuration profiles for Jamf Pro

[mm2270]

@mthakur You'll get no disagreement from me on that. You're right that it does shift this to writing JSON instead of xml or hand crafting .mobileconfig files. I kind of said as much above in my earlier post, that this is definitely NOT for the novice admin.

However, this feature is an attempt to partially fulfill this one, I think. Specifically, if you look at the mock up done by @milesleacy here, it's not all that dissimilar, but it DOES require building the framework in JSON to even be able to use a simple add/remove approach like what he mocked up.
So, while it's not the simple GUI approach we might have all hoped for, I feel it's at least a step in the right direction.
It's a first step, and I think is designed to work in conjunction with some of the other changes Jamf is making around Config Profiles, like the sliders for On/Off states they introduced in a couple of payloads, which will help avoid placing options that we don't even want into a profile.
Eventually it'll all get there, but it's going to take some time and iterations to achieve it.

[mscottblake]

A couple of us have been writing these up and posting them to GitHub.
https://github.com/MScottBlake/jamf-custom-schemas
https://github.com/chrisgrande/jamf-profile-schemas
https://github.com/joshua-d-miller/JAMF-JSON-Schema

Chris and I have talked a bit about creating a new team to host these to cut down on duplication of work. @mm2270, I can vouch for how much work the NoMAD one is and I wouldn't wish it on anyone since it's already working (as far as I can tell).

Now that I see you were also working on NoMAD, it's making me want to go create a team now...

Standby while I go get something started.

[mscottblake]

We now have a team setup in GitHub at https://github.com/Jamf-Custom-Profile-Schemas so we can group all of the custom schemas in one place and hopefully reduce duplicated effort.

Haha, and just as I finished (mostly) the NoMAD one I was working on. In looking at yours I can see it uses more advanced options overall in some places. Well, it was a good exercise for me to learn a bit about JSON anyway. I like how yours uses a "Configured/Not Configured" drop down for each item. I didn't even know that was an option (again, noob at JSON that I am). So I can learn from that for the next go around.

I'll check out the other ones too. Glad there's a more central place for these for the moment. Jamf should probably add a place here where they can be uploaded and hosted too, kind of like with Extension Attributes and other resources.

[mscottblake]

Yeah, I agree that they should, but in the absence of that, I hope this way works.

I'm just going to leave this here: https://github.com/BIG-RAT/Managed-App-Schema-Builder

[noahdowd]

@mscottblake Oh wow this is great! I'm learning so much from looking these over. Thanks!

[#19]

@mscottblake amazing work and thanks for the github. I've myself created one where I store my creations. I use your custom schema for NoMAD and it helps a lot !
I've created one for the notifications : link

[mscottblake]

@bp.studer I invited you to the team so you can include your stuff in the central repo. If anyone else wants the same, let me know and I can get you an invite.

[a_hebert]

@mscottblake I have one for blacklist/whitelist extensions in Chrome. https://github.com/Ahebrt76/Jamf-Schemas-

[lawinski]

Hey there I created a schema for Munki (here).
Feel free to upload and expand it. I haven't pushed it to git yet.

EDIT: Somebody already has a better one.

[seanism]

Anyone create any schema's for Google Chrome?

[mscottblake]

@seanism I have not and do not plan to do so. Since Chrome is developed by a corporation, it is my hope that they will embrace the technology. My focus is on open source software.

[slashnext]

how we can read this custom schema in our machine once it is deployed successfully?

[mm2270]

@slashnext The custom schema itself doesn't get deployed to any machines. It gets imported into Jamf Pro to create a GUI for you to use to set settings that get deployed to your machines. The settings themselves are no different in the end than any other configuration profile plist.

[jorge_]

@mm2270 I was able to upload this into a configuration profile for testing. Would you mind sharing how I can blacklist all extensions by default, then whitelist a only a select few with firefox? I am able to do something similar with chrome, but still trying to figure out firefox.

Has Anyone Created a Chrome one yet

Great thread. I wanted to post a default for those not familiar with JSON. You can copy/paste after finding out which value types and values you need for your custom domain settings. I found this especially easy using ProfileCreator and looking at the raw XML values then converting it to JSON.

This should save time exporting and creating new profiles with ProfileCreator while still using ProfileCreator as the reference for some application specific custom settings - ie use that GUI to find the settings you want then port it to a JSON schema so you can keep it up-to-date in Jamf Pro.

{

        "$schema": "http://json-schema.org/schema#",

    "type": "object",
    "properties": {

        "keyNameString": {
            "type": "string",
            "title": "This String",
            "description": "Enter the string value",
            "default": "myString"
        },

        "keyNameNumber": {
            "type": "number",
            "title": "This Number",
            "description": "This number is an array of choices. The default is 0",
            "default": 0,
            "enum": [0, 1, 2, 3, 4]
        },

        "keyNameBoolean": {
            "type": "boolean",
            "title": "This Boolean",
            "description": "This boolean is true or false. The default is false.",
            "default": "false"

        }

    }

}

[jbisgett]

I see there is one for NoMAD, but what about NoMAD Login?

[mscottblake]

@jbisgett I've been meaning to work toward creating one, but I haven't had a lot of time lately. Check back once in a while and there will be one eventually.

I'm still having a little trouble with this. I am trying to enable the "Turn on new meeting experience" checkbox in the Teams settings. I cannot simply replace the file because it contains other important user settings.
I've found the file and the key.

/Users/r[USER]/Library/Application Support/Microsoft/Teams/desktop-config.json

and

{"appPreferenceSettings":{"callingMWEnabledPreferenceKey":true}

but I am having trouble making it work.

I tried using the tool found here to no avail. I built the following schema, uploaded it to the custom settings payload then deployed to a test device but it had no effect.

Am I approaching this the wrong way? Can someone point me in the right direction?

[djrory]

Would it be simpler to just edit the JSON with a script to change the value to TRUE?

[prbsparx]

Maybe a group of us can work on developing a script that can be added to Xcode/build tools to generate a basic JSON Schema for all the preferences available in source code. I assume there's a way to scan the source code for defaults.

[mm2270]

@djrory The problem, I think, is that you're using a custom application schema to (try to) update the settings in a json file, which isn't what this is used for. What the custom schemas ultimately do is give you a simple GUI interface for configuring and sending out Configuration Profiles, which are just xml/plist files. IOW, I don't believe a Config Profile can affect a json file on the local machine. You'll probably have to directly manipulate the json file settings and see if it works to apply the change. If it does, there's likely a way it can be scripted.

Either that, or keep digging and investigating to see if there's an actual plist setting and value that stores that same item. If you find one, then using a Custom Application Schema would make sense.

Hello, I have the following Schema setup where I want to bock all Chrome Extensions except the ones our School has approved. I attached a picture of what we have for a Schema.

Then in Properties I have the extension ID set to under Add/Remove key hoping to block them all and then I am adding the Extension ID of the ones we want to allow. However it is not working when I test with a test account on a laptop and I have it scoped to the test account and the laptop being used. Even just for testing the I took the one Key I had with the out and then just left the one extension ID I wanted to allow in there, but set to block and was still able to add it. I was hoping to block Chrome extensions this way instead of using a plist as we have done that before and it works. Any advice would be great. Hope I posted this in the right area.

[Santosh]

Great thread.Do we have a similar JSON file for Microsoft Office/Office 365 aswell ?

[sdagley]

@Santosh There are already built-in configurations for Microsoft in the Application & Custom Settings editor. Select Source->Jamf Repository and then the Preference Domain popup will list several com.microsoft domains to choose from.

[Santosh]

@sdagley correct.

that's what i understood for the JAMF Documentation. We are using JAMF PRO 10.19 Under Application & Custom Settings editor,when i Select Source as Jamf Repository i dont see any Preference domain as popup
