Dear community members!

A very common problem of our users is to use an external database as data source in an IRIS production. As many of you already know, we have two ways to connect directly to an external database, the first one is using an ODBC connection, the second is using JDBC.

In our example we are going to create a connection using JDBC, and we are going to build a simple Docker's project, in this way you will be able to modify the example as you wish.

The code is available from this URL: https://github.com/intersystems-ib/workshop-sql-jgw

In our docker-compose.yml file we are going to

Hi Developers!

Suppose you have a persistent class with data and you want to have a simple Angular UI for it to view the data and make CRUD operations.

Recently @Alberto Fuentes described how to build Angular UI for your InterSystems IRIS application using RESTForms2. 

In this article, I want to tell you how you can get a simple Angular UI to CRUD and view your InterSystems IRIS class data automatically in less than 5 minutes.

Let's go!

For quite some time I am bored by slowly starting Docke Demos from OEX.
I type

docker-compose up - d

and after a few seconds

docker-compose logs

And I just see ISC Agent was started and is hanging around
No IRIS instance is up yet.

IRIS is a powerful platform and one of the new features is the Java Business Host (DOC: Connecting Systems Using Java Business Hosts) that allow you to develop Business Services and Business Operations directly in Java (JavaDocs of the InterSystems Gateway Package).

I was testing this feature using an IRIS Docker image, but this image doesn't come with Java, the image is a bare Ubuntu image plus IRIS. So I had to build a new image adding the Java stuff. After some research I finally get this Dockerfile:

Hi Developers!

"objectscript.conn" :{
      "ns": "IRISAPP",
      "active": true,
      "docker-compose": {
        "service": "iris",
        "internalPort": 52773
      }

I want to share with you a nice new feature I came across in a new 0.8 release of VSCode ObjectScript plugin by @Dmitry Maslennikov and CaretDev.

The release comes with a new configuration setting "docker-compose" which solves the issue with ports you need to set up to make your VSCode Editor connect to IRIS. It was not very convenient if you had more than one docker container with IRIS running on the same machine. Now, this is solved!

Read below how it works now.

Hi, I would like to tell you how easy it is to spin up IRIS for Health docker container in compute engine(VPS) in google cloud.

I know that to run IRIS for Health in AWS is pretty simple and straightforward, but I wanted to tried if its same easy in GCP environment.

Create vm instance. 2GB RAM is more than enough.

I used Debian 11 as Linux distro.

Standart persistent disk is cheaper.

Don’t forget to allow http, https traffic

Last thing for setting up virtual machine is allow external ports in firewall rules.

I allow here only 52773 which is for web user interface.

Announcing the InterSystems Container Registry web user interface

InterSystems is pleased to announce the release of the InterSystems Container Registry web user interface. This tool is designed to make it easier to discover, access, and use the many Container images hosted on ICR.

The InterSystems Container Registry UI is available at: https://containers.intersystems.com/contents

Community Edition Containers

When you visit the ICR user interface, you’ll have access to InterSystems' publicly available containers, including the IRIS community edition containers.

IS anyone else having issues logging into the container registry?  I log in and it just says logging in and hangs?

There are several great articles in the community showing how to use Jupyter and InterSystems IRIS together, and I encourage you to check them out in the link at the end of this article for more in depth understanding.

This is just another one, the difference is on the simplicity. Do you want to just start a container where Jupyter is already connected to an IRIS instance? Then this is for you!

By simply running docker-compose up you already will gain access to a working environment with a couple of examples in it. I don't want to ruin the simplicity so give it a try.

Hi developers!

Those who code IRIS solutions in VSCode using Docker often use the convenient ObjectScript menu, which contains links to Management Portal, Class Reference, Unittest portal, Productions, etc.

While drilling down to a Dev Container to code Embedded Python there is no such option, at least within my settings:

So I don't know how to connect to it. 

Thoughts?

Hi folks!

I'm playing with Embedded python with IRIS trying to do some 'hello-world' exercises.

I'm running IRIS in container and have the following python code:

# Program to test coding with IRIS

print('Hello World')

# Run IRIS Class Method import iris
print(iris.cls('dc.sample.ObjectScript')).Test()

So, when I execute it, I get the following:

$ /usr/irissys/bin/irispython /irisrun/repo/python/app.py
Hello World
Traceback (most recent call last):
  File "/irisrun/repo/python/app.py", line 7, in <module>
    import iris
  File "/usr/irissys/lib/python/iris.py", line 14, in

I have installed Iris in Docker container with the above version.  I need to create an additional user to log in via ssh.  I have created a user and put in both the irisuser and irisowner groups, and created a user in iris with permissions.  But, when I run "iris session iris" I originally got an error about permissions: /usr/irissys/bin/irisdb: Permission denied.
I looked @ the /usr/irisys directory and the permissions was only (r-x------).  I changed to (dr-xr-xr-x.)and now I get a different error:
Invalid ownership for ./irisdb
Any suggestions? 

I get the error below when trying to login to an account i just created. Login details used is my email as username and a password.  Any ideas?

##Error response from daemon: Get "https://containers.intersystems.com/v2/": unauthorized: BAD_CREDENTIAL##

I am trying to get the Apache Web Gateway with Docker running on a development RHEL 8 machine so I do not have to config the Web Gateway and Apache apart from each other. I noticed the Apache Web Gateway docker image is using IRIS Community Edition. However when I try to run the docker image with podman I am running into issues with the IRIS setup. I was wondering if someone could help me. When I get the image to run I am seeing the following errors...

[iris]       | [ERROR] Required Linux capability cap_setuid is missing.
[iris]       | [ERROR] Required Linux capability cap_dac_override is

Docker 20.10.14 (released March 23, 2022) changes the Linux capabilities given to containers in a manner that is incompatible with the Linux capability checker in InterSystems IRIS 2021.1 (and up) containers. 

Users running Docker 20.10.14 on Linux will find that IRIS 2021.1+ containers will fail to start and the logs will incorrectly report that required Linux capabilities are missing.  For example:

[ERROR] Required Linux capability cap_setuid is missing.[ERROR] Required Linux capability cap_dac_override is missing.[ERROR] Required Linux capability cap_fowner is missing.

Hi folks!

We have a bunch of templates on OEX that provide a handy foundation for building a particular application with IRIS.  And the basic principle of each and every template is that we take vanilla IRIS images, load code, and files into the image using Dockerfile, and create a new docker image as a solution. And then we develop running this image and rebuilding it when returning to development.

Some developers ask me why we need to build the docker image to work with the code. Indeed, if at the end of the day I need to develop a ZPM package and not a docker image why don't run the vanilla image and load the code and everything in it? 

The problem I have with the building image approach is that often I can wait a lot to build an image and it fails on some Objectscript problem in the source that I cannot fix as the image is not building. and 

Any thoughts? How do you develop with docker?

For quite some time InterSystems IRIS supports such thing as Merging CPF. So, with help of this it should be possible to define only desired changes in configuration. And get them applied even with vanilla Docker image. 

And I though it could be useful when used with Dockerfile. Use this way to configure IRIS during docker build instead of using Installer manifest.

While the documentation of configuring authentication with Kerberos for IRIS on Linux servers is sparse, for docker i found no docs at all. Assuming I would be able to adapt the requirements from linux to docker (on linux host) I had no success at all. Has anyone successfully done this?

Even with "do ^REDEBUG" set to FFFFFFFF the log did not help much, I always get "Kerberos error getting initial credentials with password; KDC reply did not match expectations".

Great news, the extension to Docker Desktop for InterSystems Container Registry is now publicly available for everyone.

It is already available in the marketplace in Docker Desktop. It was published today, and it requires restarting Docker Desktop to see it.

Hi developers!

Here is the score of technical bonuses for participants' applications in the InterSystems Interoperability Contest: Building Sustainable Solutions 2022!

Hello everyone, I’m a French student that just arrived in Prague for an academical exchange for my fifth year of engineering school and here is my participation in the interop contest.

I hadn’t much time to code since I was moving from France to Prague and I’m participating alone, so I decided to make a project that’s more like a template rather than an application.

I wanted to participate since my field (Data Science and AI) is not often linked with sustainability and the contest was a way for me to express myself in this important subject that is sustainability and Environnement.

As you know,

I am happy to share with you my first experience of using a docker container version of IRIS for Health to explore your interest in using or having a trial by taking the advantage of a docker container that is lightweight, and easy to deploy. This cookbook will go through the implementation steps using the GitHub repository called ENSDEMO written by Renan Lourenco.

Steps for setting up an IRIS for Health Community Edition docker container environment

1. Docker up and running
2. Download the docker image

docker pull containers.intersystems.com/intersystems/irishealth-community:2022.2.0.304.0

3. Clo

Hello, Community, I tried to deploy online demo for interoperability-test app. I see it errored because BuildKit is not available. Can the Docker be configured to support BuildKit?

Hello,

I'm using CircleCI to spin up the image `store/intersystems/irishealth-community:2021.2.0.649.0`.

When building the application we are getting messages that say:

ERROR #5373: Class 'EnsLib.HL7.Message', used by 'Package.Class', does not exist
Skip class Package.Class

Other missing classes seem to include, but not limited to:

Ens.BusinessProcessBPL
Ens.BusinessService
EnsLib.RecordMap.ComplexChild
EnsLib.EDI.XML.Document
Ens.Request

Binding to a port and looking the management portal, it seems we have the namespace HSLIB and some classes:

As far as we understand, these classes should be available

Hi, 

I have a problem when starting the docker container that the collation is standard US

sample:

docker run --name iris1 -d --publish 1972:1972 --publish 52773:52773 containers.intersystems.com/intersystems/iris-community:2022.1.0.209.0 --check-caps false

After the installation I like to import existing classes and globals but it failed due to an collation error 

We usually use DEUW = German3 

if I change it manually - in the management portal / NLS... -  to DEUW it works fine. (By the way.... the managemet portal  shows all in German due to the Linux version)

Question: is there a way to

Machine Learning

Hi all

I'm testing migrating our existing installers (without ZPM) using the docker dev template as a basis with a commercial image and licence key.

So far everything builds as I expect, but the one issue I have is the production doesn't apply itself automatically.

In my iris.script I have custom installer that uses this manifest below but it does not observe the last three steps

<NamespaceName="${DataNamespace}"Create="no"><Invokename="Credentials"Class="GOJ.IrisApp.Install.ApplicationLayer"Method="AddCredentials"CheckStatus="1"><Argname ="Namespace"Value="${DataNamespace}" />

I was wondering if someone could help me. I do not have docker available to me however a lot of the Open Exchange apps require it. Since I am using a Virtual Windows Machine I can not get docker installed, so I was wondering how to get around this? Someone at GS2022 suggested looking at the docker_compose.yml to figure out how to get around docker, but I am not sure I understand how to read it. 

Does someone have any quick solutions to get around docker compose? Or can tell me how to read a docker compose so that I can install some Open Exchange and or additional InterSystems components?

Thanks
