A while back we created JSON2Persistent which does this for you in a consistent way without AI :)

do ##class(ISC.SE.Tools.JSON).GenerateClasses("path/to/sample.json", "MyDataModel.JSONPackage", "ClassName", 0, 1)
// or
do ##class(ISC.SE.Tools.JSON).GenerateClassesFromStream(jsonStream, "MyDataModel.JSONPackage", "ClassName", 0, 1)

// and then use that class

Set mymessage = ##class(MyDataModel.JSONPackage.ClassName).%JSONImport(mysourcestringorstream)
Set mymessage.%Save()

// and it's SQL addressable

SELECT * FROM MyDataModel_JSONPackage.ClassName

Seems this trusty bit of code I've been using for a while no longer works on 2025.1

I use this tidbit to get an external ip

curl -s http://whatismyip.akamai.com/

If you want the docker-host ip and not the external ip, I use host networking and then use

hostname -I
