#Docker

Most of us are more or less familiar with Docker. Those who use it like it for the way it lets us easily deploy almost any application, play with it, break something and then restore the application with a simple restart of the Docker container.
InterSystems also likes Docker.The InterSystems OpenExchange projectcontains a number of examples that run InterSystems IRIS images in Docker containers that are easy to download and run. You’ll also find other useful components, such as the Visual Studio IRIS plugin.

Hi Developers,

Please welcome the new video specially recorded by InterSystems Product Manager @Bob Kuszewski for the 3rd InterSystems Online Programming Contest on InterSystems IRIS Native API:

⏯ Using the IRIS Native API GitHub Template

What’s the contest about?

In the last year, InterSystems added and expanded Native APIs for Java, .NET, Python, and Node.js. The Native API provides high speed access to globals, the ability to instantiate and use ObjectScript objects, and fine-grained control over transactions.

⏯ Leveraging Containers for DevOps

Hi folks!

When I start IRIS in docker every time I do the following:

$ docker-compose up -d --build

$ docker-compose exec iris iris session iris

USER>zn "NAMESPACEINEED"

Is it possible to have an open terminal command connect to a particular namespace?

Allow limited durability for demo and development IRIS-Docker-micro-Durability During development of a container based demo I found the need to access a fresh docker
an instance of IRIS image (e.g intersystems/iris-community:2020.2.0.199.0) over and over.
To bypass loading my code repeatedly, I developed this workaround.

Docker support

The principle of a persistent IRIS database outside the container is unchanged.
But now the whole setup is moved into Dockerfile and docker-compose.yml

Prerequisites

Make sure you have git and Docker desktop installed.

I have Mac OSX and Docker Desktop 2.2 (Engine 19.03).

I have a REST service running on my localhost (Mac) and I was trying to consume it from IRIS running in a Docker container.

If you try something like that don't use localhost as HTTP Server setting (using a Business Operation for example).

You have to use host.docker.internal.

Hi Developers!

InterSystems Online Programming Contest is over. Thank you all for participating in our IRIS Competition!

As a result - 20 great apps! And now it's time to announce the winners! 

Hi Community!

The registration phase for InterSystems Online Programming Contest ends today and we will start the voting week!

Now we have 20 applications - so you have a set of applications to choose from!

How to vote?

This is easy: you will have one vote, and your vote goes either in Experts nomination or in Community nomination.

For standalone installations I always recommended to use custom namespaces and not the USER namespace.

However, what about Docker?

In many Dockerfiles I see the creation of additional namespace, but why, if only one namespace is required?

What do you think?

⏯ How to Create and Submit an Application for InterSystems IRIS Online Programming Contest 2020

I'm building a container from store/intersystems/iris-community:2019.4.0.383.0 .

I need to add my folder to the LD_LIBRARY_PATH  so that my custom shared library would load at runtime.

How can I do that?

Here's what I tried:

ARG IMAGE=store/intersystems/iris-community:2019.4.0.383.0
FROM ${IMAGE}

USER root

ENV MYDIR /usr/mydir

ENV LD_LIBRARY_PATH $MYDIR:$LD_LIBRARY_PATH

RUN mkdir "$MYDIR"; \
	chown -hR $ISC_PACKAGE_IRISUSER:$ISC_PACKAGE_IRISGROUP $MYDIR; \
	chmod -R 777 $MYDIR; \
	echo "LD_LIBRARY_PATH=\"$MYDIR\"" >> /etc/environment; \
	echo "$MYDIR" >> /etc/ld.so.conf.d/my.

⏯ Durable Data Storage with Containers

Hi developers!

Suppose you have a Github repository with ObjectScript classes but without a Docker environment.

Recently I published a repository with a set of files that form a universal Docker and VSCode environment to let you either import and run your repository in InterSystems IRIS Community Edition on Docker or turn your repository into Docker and VSCode environment for InterSystems IRIS Community Edition.

So in one sentence:

Unpack these files in your folder and you have the Docker and VSCode environment for your InterSystems IRIS ObjectScript application!

See the details below.

⏯ How to Enable Docker and VSCode to Your InterSystems IRIS Solution

Hi Everyone,

I've been working on deploying an IRIS for Health environment in EKS. There is a video session in the InterSystems learning portal about this feature but I have not succeeded in finding the proper documentation and resources to use this in my Kubernetes cluster.

Has this been deprecated/discontinued? Any idea where can I find the resources? Should I stick to StatefulSets instead of using the IrisCluster resource type provided by this operator?

Last time we launched an IRIS application in the Google Cloud using its GKE service.

And, although creating a cluster manually (or through gcloud) is easy, the modern Infrastructure-as-Code (IaC) approach advises that the description of the Kubernetes cluster should be stored in the repository as code as well. How to write this code is determined by the tool that’s used for IaC.

In the case of Google Cloud, there are several options, among them Deployment Manager and Terraform. Opinions are divided as to which is better: if you want to learn more, read this Reddit thread Opinions on Terraform vs. Deployment Manager? and the Medium article Comparing GCP Deployment Manager and Terraform. 

If you had the opportunity to change something in the IRIS Interoperability Message Viewer, what would you do?

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.

Our goal is to be able to keep track of the entire code and configuration of the IRIS instance.

Hi Developers!

Another way to start using InterSystems ObjectScript Package Manager is to use prebuilt container images of InterSystems IRIS Community Edition and InterSystems IRIS for Health Community Edition.

We deploy this IRIS images on DockerHub and you can run it with the following command:

docker run --rm -p 52773:52773 --init --name my-iris -d intersystemsdc/iris-community:2019.4.0.383.0-zpm

Launch a terminal with:

docker exec -it my-iris iris session IRIS

And install zpm-module as:

USER>zpm 

zpm: USER>install objectscript-math

[objectscript-math] Reload START

[objectscript-math] Reload SUCCESS

[objectscript-math] Module object refreshed.

[objectscript-math] Validate START

[objectscript-math] Validate SUCCESS

[objectscript-math] Compile START

[objectscript-math] Compile SUCCESS

[objectscript-math] Activate START

[objectscript-math] Configure START

[objectscript-math] Configure SUCCESS

[objectscript-math] Activate SUCCESS

zpm: USER>

And use same commands for InterSystems IRIS for Health using the tag: intersystemsdc/irishealth-community:2019.4.0.383.0-zpm

The images are being published on IRIS Community Edition and IRIS Community Edition for Health repositories of Docker Hub.

We will update tags with every new release of IRIS and ZPM.

Happy coding!

Hi Developers!

I stuck with one interesting problem. 

For example, let's use this template repo. If you build this container A using docker-compose and then run the container it exposes REST-API  which is available on:

localhost:52773/person/all

The question is how to make this REST-API accessible from another docker container B running on the same machine? E.g. with IRIS 2019.4 Community from this repo?

The problem is that for the second container localhost it's something which belongs to container B.

I think I need to set up a network between containers somehow. E.g. using docker-compose. But is there any simpler way?

Some of you on the Developer Community have probably interacted with @Luca Ravazzolo if you are interested in cloud and container topics... If so, you'll enjoy Episode 2 of our new podcast — we chatted with Luca about Kubernetes and the InterSystems Kubernetes Operator. He does a great job of explaining the technology and its benefits here!

Is possible config a docker-compose.yml to start arbiter-2019.4.0.383.0-docker.tar alone ? 

What parameter you need ?

i can't find a simple sample

Hi guys,

I thought I test the InterSystems IRIS for Health 2020.1, the Docker image. but for some reason, the container only lives for about 10 seconds and I can see from the message.log file that as soon as IRIS starts it then performs shutdown thus ending also container. Anyone else seen this?

here is the message.log part

Hi everyone,

I am very pleased to announce that the Readmission Demo has been released as open source. Many thanks to the Solution Factory team that worked hard on making this possible.

Here are the changes:

• It is now running on top of IRIS Community 2019.3.0.308.0.
• It has synthetic data based on Synthea instead of the real data we were using before. But the machine learning models are 100% real
• Image RRLACESrv has been renamed to “image-riskengine”
• Image “readmissionsrv” has been renamed to “image-risksrv"
• We refactored a lot of the code on image-riskengine to look better.

Hi all,
I'm having issues with mounting custom database on top of IRISHealth 2019.1 docker container. Data gets mounted only in Read-only mode. This means read operations are successful but I couldn't make the image  with databases mounted  in Read/write, both modes. Is anyone having similar issue?
