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:

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

Hi developer folks!

Thanks to all of you who start the development with InterSystems IRIS from the basic development template!

Recently, thanks to @Dmitry Maslennikov's contributions I've updated the Dockerfile to make the development simpler, images lighter and the building process faster. And it looks more beautiful too ;)

Here is what changed:

DB Migration using SQLgateway

Thanks to @Yuri Marx we have seen a very nice example for DB migration from Postgres to IRIS.
My personal problem is the use of DBeaver as a migration tool.
Especially as one of the strengths of IRIS ( and also Caché) before is the availability of the
SQLgateways that allow access to any external Db as long as for them an access usinig 
JDBC or ODBC is available. So I extended the package to demonstrate this.

Hi Developers!

This is yet another short post that is intended to simplify developers' life. Now we'll talk about how to make GitHub run unit tests with every push to the repository by adding just one file to the repo. For free.  On Github Cloud. Sounds great, isn't it?

It is possible and very easy to do. Credit goes to @Dmitry Maslennikov (and his repo), ZPM Package Manager, and GitHub Actions.  Let's see how this all works!

Hi,

I have wrote an article about how to install the intersystems cache driver in a Docker container, and then deploy it using Azure Functions: 

How to run a (Python) Azure Function as a Docker container & Deploy it using Bicep | Victor Sanner

This might be useful to others, especially the dockerfile which I have copied below. This builds a debian docker container and installs the Intersystems Cache driver, which python can then use :)

I am new to Intersystems, in our project we are directly connecting to the server (environment) using  Intersystems VSCode extensions and publishing our changes from local machine. This is not the way we usually do as development process.

Is it possible to implement continuous integration ? So that developers can check-in their code in GIT Hub and can integrate Jenkins and automate the deployment?

Could you please help me on this ?

InterSystems Reports is powered by Logi Report (formerly named JReport), a product of Logi Analytics. InterSystems Reports is supported by InterSystems IRIS and InterSystems IRIS for Health. It provides a robust modern reporting solution that includes:

  • Embedded operational reporting which can be customized by both report developers and end users.
  • Pixel-perfect formatting that lets you develop highly specific form grids or other special layout elements for invoices, documents, and forms.
  • Banded layouts that provide structure for aggregated and detailed data.
  • Exact positioning of headers, footers, aggregations, detailed data, images, and sub-reports.
  • A variety of page report types.
  • Large-scale dynamic report scheduling and distribution including export to PDF, XLS, HTML, XML, and other file formats, printing, and archiving for regulatory compliance.

InterSystems Reports consists of:

  • A report designer, which provides Design and Preview Tabs that enable report developers to create and preview reports with live data.
  • A report server which provides end users browser-based access to run, schedule, filter, and modify reports.

From InterSystems documentation.

This article focuses on the Server part of InterSystems Reports and provides a guide on running Report Server in containers while persisting all the data.

Hi,

I am running InterSystems iris 2021.1 from the container and I have version 2020.1.1 is installed locally. While running studio locally I am getting below error message:

"Version mismatch. Studio version 2020.1.1 unable to connect to server version 2021.1
Upgrade to a later version of the client to resolve this error"

Looking Forward

Thanks

Function as a service (FaaS) is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage application functionalities without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. Building an application following this model is one way of achieving a "serverless" architecture, and is typically used when building microservices applications.  

Wikipedia

FaaS is an extremely popular approach to running workloads in the cloud, allowing developers to focus on writing code.

This article will show you how to deploy InterSystems IRIS methods in a FaaS way.

Hello,

The title says it all. I’m building an IRIS image with docker-compose using a separate Dockerfile. Pretty straightforward procedure: I import a Installer script inside the container containing a Installer Manifest I defined. Within the manifest, I create a namespace with code and data databases in separate locations. My intention is to keep the code database inside the container, so whenever I build the container, the imported code is replaced. The data, however, should be persistent.

We are developing some containarized cloud application level iris instances and using CPF Merge to do a lot of the initial buildout for the iris instance (i.e.  create databases, namespaces, map globals/routines, ecp setup, etc...)

I am trying to figure out how to get package mappings into a namespace config, via cpf merge if possible... ?

 

This is the document I am working from to develop the cpf merge file -

New Kubernetes Exercise!

Hi All! For those of you who attended experience labs at the 2021 Virtual Summit, you may recall that one of the lab sessions was around Kubernetes. We've now converted that lab to be fully on-demand. You can launch a small cluster of VMs and follow the exercise to manage your Kubernetes cluster, deploy InterSystems IRIS containers to it, and watch its self-healing nature when destroying a pod.

It's a great introduction to Kubernetes if you are interested! See here: Achieving High Availability with InterSystems IRIS and Kubernetes

Hi Community!

I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects  check any on Open Exchange.

What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?

We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.

So every developer performs the following:

  1. Check out the code from repo
  2. Install/Run local IRIS installation
  3. Create a new namespace/database for a project
  4. Import the code into this new namespace
  5. Setup all the rest environment
  6. Start/continue coding the project 

If you dockerize your repository this steps line could be shortened to this 3 steps:

  1. Check out the code from repo
  2. Run docker-compose build 
  3. Start/continue coding the project 

Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.

You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!

Hi folks!

Sometimes we need the docker image of the InterSystems IRIS solution we build to be published on some docker registry. The cases could be:

  1. Deploy it then in Kubernetes cluster
  2. Let your pal run the image of your public repo without building it locally.

You can push the image to Docker Hub Registry or Github Registry.

In this very short article, I provide a way how to do it automatically on every push to your GitHub repository.

WebSocket Client with embedded Python

This is a demo to make use of a simple WebSocket Client with Embedded Python in IRIS.

To continue my series of WebSocket Client I have added an example written in Python.
The most impressive experience was how easy the writing and testing of the client was
which happened total offline from IRIS.
Embedding, running and feeding the client with data from IRIS was also incredibly simple.

Hi developers!

ZPM Package Manager is getting more and more popular and thus the library of packages is growing.

And thus some solutions or samples can be built with InterSystems IRIS and one or two packages installed.

I want to share with you iris-docker-zpm-usage-template - a template that can be used exactly for this purpose.

Good day,

I'm trying to get IRIS to run on a new MacBook with a Apple M1 Pro chip. Local installs did not run, so I switched to docker containers. When I execute following command "docker run --detach --publish 52773:52773 --volume /Users/joost/Docker/iris/data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 --init store/intersystems/iris-community:2021.1.0.215.0" an image is pulled and a container is created but the IRIS instance does not run. The log gives me the following output:
