Docker is a software technology providing containers, promoted by the company Docker, Inc. Docker provides an additional layer of abstraction and automation of operating-system-level virtualization on Windows and Linux.

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.

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!

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.

Jupyter and IRIS - The Simple Version

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!

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?

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?

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:

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?

Testing MergeCPF feature

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.

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 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.

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

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

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

Installing Apps without Docker

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.

I would say it is a post of pain after years of using InterrSystems IRIS Docker images in many projects.

And I hope InterSystems will hear me and do something with it.

We have a lot of issues with Docker images, but I see no progress in solving them.

  • containers.intersystems.com - any new releases substitute previous versions, makes build useless
    • ARM64 images have separate names, and it makes a pain to use them
  • flags in iris-main, appears and disappears from version to version, which may fail the start the container
  • healthcheck does not work as expected
