Embedded python gives the option to load and run python code in the InterSystems IRIS server. You can either use library modules from Python pip, like numpy, pandas, etc, or you can write your own python modules in the form of standalone py files.
So once you are happy with the development phase of the IRIS Embedded Python solution there is another very important question of how the solution could be deployed.
One of the options you can consider is using the ZPM Package manager which is described in this article.
This project is implemented as a tool for viewing temperature data taken from a temperature sensor installed in Rasperry PI and located in a remote place where there is Internet, for example, in dacha.

We have just released a minor update to the package manager, which has been renamed from ZPM to IPM as I explained in November. It purely a bug fix release, properly interpreting ROBOCOPY return codes and fixing a regression that prevented installation of certain packages.
Often when we install a code package we want to make some post-install settings, e.g. call to a method, set up a configuration file.
This article describes how to do this with the ObjectScript Package Manager.
To make any post-install calls you need to add <Invoke> elements into <Invokes> tag to the module.xml. Each <Invoke> element can have nested <Arg> elements if you want to pass params to the method:
ZPM is a great tool. You can compose a large WebApplication following the existing examples. But differently, to Classes, Routines, Macros, or Globals I found no direct way to deploy a few additional CSP pages directly into an existing Namespace without touching the existing content.
A side issue was to find a solution that is independent of WIN or Linux directories.
Many of you are looking for samples on how to work with InterSystems IRIS Analytics, formerly known as DeepSee.
There is a Samples BI module with Patients and Holefoods examples which is available on Github with source code. The installation steps are clear but take time.
Recently we added the option to run IRIS Community Edition containers with ObjectScript Package Manager (ZPM) on board. This simplifies the installation to the "run-one-command" step for the modules submitted to ZPM Community Registry. And thus we can benefit the Samples BI installation with ZPM.
And here is how you can run it on your laptop. Let's go!
I'm just starting off with ZPM and noticed that examples of library-type packages and full applications abound, but I have not unearthed any that demonstrate packaging an interop production. It doesn't seem like it would be too big of a jump from a full application to an interop production, but that is likely ignorance speaking.
So, does anybody know if this is possible/advisable -- or if I am just way off on the intent of ZPM?
Anybody willing to share a method form the ZPM cli (or othewise) where zpm will "Install package if not already installed?" I would want this to count for updates too I think as I would want to control that too.
Open Exchange (OEX) is getting more and more popular and more and more developers consider publishing their apps in the public package managerregistry.
This is really great!
So the topic of thoughtful naming convention is getting more important and even critical. Let's discuss?
I'm playing with ZPM. Accidentally dropped a production. How can I recreate it programmatically? I see Ens.Director.StartProduction, StopProduction, and even DeleteProduction but I don't see CreateProduction anywhere. Please help 😊

So if you run this container with IRIS CE or IRIC CE for Health you can immediately start using ZPM and install packages from Community Registry or any others.
What does this mean for you?
It means, that anyone can deploy any of your InterSystems ObjectScript application in 3 commands:
run IRIS container;
open terminal;
install your application as ZPM package.
It is safe, fast and cross-platform.
It's really handy if you want to test a new interesting ZPM package and not harm any of your systems.
Suppose, you have docker-desktop installed. You can run the image, which wiil pull the latest container if you don't have it locally:
