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.

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:

Hi developers!

Every day coding with IRIS and docker I call the following 3 commands in VSCode terminal. Always the same for any projects:

docker-compose build   ; to build the container

docker-compose up -d   ; to run the IRIS in container

docker-compose exec iris iris session iris ; to open the IRIS terminal

Is there any way to map the key sequence which will type me the rest?

e.g.

0 2
0 470

As a former JAVA developer it has always been a challenge to decide which database was the most suitable for the project we were going to develop, one of the main criteria I used was their performance, as well as their HA configuration capabilities ( high availability). Well, now is the time to put IRIS to the test with respect to some of the most commonly used databases, so I've decided to create a small Java project based on SpringBoot that connects via JDBC with a MySQL database, another of PostgreSQL and finally with IRIS.

Hi Everyone!

You're very welcome to watch the new video on InterSystems Developers YouTube, recorded by @Evgeny Shvarov in the new format called "Coding Talks":

GitHub Flow with InterSystems IRIS: Edit with VSCode, Test with Docker, Commit, Push, Pull Request

Hello,

I've always worked with typical web applications (a bunch of code files that sit in a server that connects to an RDS). Now our team is responsible for different IRIS for Health environments. We are currently working to set up the local dev environment and this is the current scenario:

* IRIS for Health local development server is running in a container

* Developers are using VSCode with the objectScript plugin

* GitHub as a version control system for the code and configuration.

Hi Developers,

While starting the development with IRIS we have a distribution kit or in case of Docker we are pulling the docker image and then often we need to initialize it and setup the development environment. We might need to create databases, namespaces, turn on/off some services, create resources. We often need to import code and data into IRIS instance and run some custom code to init the solution.

And there plenty of templates on Open Exchange where we suggest how to init REST, Interoperability, Analytics, Fullstack and many other templates with ObjectScript. What if we want to use only Python to setup the development environment for Embedded Python project with IRIS?

So, the recent release of Embedded Python template is the pure python boilerplate that could be a starting point for developers that build python projects with no need to use and learn ObjectScript. This article expresses how this template could be used to initialize IRIS. Here we go!

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!

Is anyone like me, and felt really jealous that they didn't have enough points to acquire the IRIS-based Raspberry Pi system when it was offered? Do you have a spare Raspberry Pi 4 handy? If so, I'll walk you through setting up Docker and IRIS on your Raspberry Pi so you can have the smallest IRIS computer in town!

¡Hi everybody!

As you likely are aware, the new version of InterSystems IRIS for Health (I4H) it's already available in Docker Hub. It's the Community version and is free and fully functional. There have been comments about it in other articles and posts,... so today I won't add anything about features. Here I want to explore "the mistery about the disappearance, or better, absence of our persistent data when we run a container with the durable option" (I didn't find a terrifying font to emphasize the thriller... post editor is not terrific for styling smiley ) .

Hi All,

Who, in the age of digital transformation, doesn't want to reap more benefits out of any process, procedure, and resource we have? At InterSystems Solution Developers Conference (part of InterSystems Global Summit 2018) we will have sessions on how to improve the way applications are built with modern tools like Docker containers, Gitlab, Circle CI, Travis, etc., how continuous integration and continuous delivery (CI/CD) processes can help us deliver more value quickly to the end-user, and how we can start thinking about modernizing traditional applications.

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.

IRIS Api Tester

Hello Community!!

I just upload my lastest application "IRIS Api Tester" to the Open Exchange.

It's a docker project with InterSystems IRIS + Newman that will allow you to test your Postman Collections in a quick and easy way..

It's ready to work out of the box, you just have to clone the repo: https://github.com/daniel-aguilar-garcia/irisapitester

Run the docker-compose file:

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.

Application Errors Analytics

Hi Developers!

As you know the application errors live in ^ERRORS global. They appear there if you call:

d e.Log()

in a Catch section of Try-Catch.

With @Robert Cemper's approach, you can now use SQL to examine it.

Inspired by Robert's module I introduced a simple IRIS Analytics module which shows these errors in a dashboard:

InterSystems IRIS in Containers

InterSystems has also released IRIS as containerized deployments. This post is to demonstrate how InterSystems IRIS and applications those rely on IRIS a backend can be packaged into an image and be run in other machines in containers and how simple it is to do that.

A container runs image/s which have all the necessary executables, binary code, libraries, and configuration files. And the images can be moved from one machine to another, and an images repository like Docker Hub can simplify that process.

I have used an application from Open Exchange for this demo.

Trying to make some scripts to do some IRIS initialization during startup, I noticed that iris start and particularly stop takes too much time, and it starts to many processes in the background.

nostu is mostly useless for system initialization but could help in some scenarios, such as setup passwords, but it is still too slow

    iris session IRIS -B

For instance, I have no idea why it starts so many AUX processes, even during NOSTU. With a normal start with no extra volumes attached, just plain start, I see no reasons to have so many AUX processes as well.

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.
