Hi community members!

I'm trying to deploy a container based on IRIS Community for Health ML image available from this url but when I start the container the memory consumption skyrockets to 99% making impossible to work with the instance (it never goes below the 95% of the memory). When I do the same with the IRIS Community for Health image it never goes over 80% of memory.

IRS Docker micro Durability

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.

It is a reduced variant of Docker - light weight durability

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.

Errors in docker run

Has anyone seen this before? I'm new/bad at Docker and not even sure how to debug.

$ sudo docker logs <container>
[INFO] Starting InterSystems IRIS instance IRIS...
[INFO] Unable to read the startup.last file to identify the location of the write
image journal file (IRIS.WIJ) that was last in use by this instance. Please
fix the permissions of the startup.last file.

Hi everyone,

Learn about iris-lockeddown, a version of the InterSystems IRIS data platform container designed to work with the most stringent container security policies:

For those that, at some point, need to test what means that of ECP for horizontal escalability (computing power and/or users and processes concurrency), but they're lazy o have no much time to build the environment, configure the server nodes, etc..., I've just published in Open Exchange the app/sample OPNEx-ECP Deployment .

The InterSystems Kubernetes Operation (IKO) version 3.3 is now available via the WRC download page and the InterSystems Container Registry.

IKO simplifies working with InterSystems IRIS or InterSystems IRIS for Health in Kubernetes by providing an easy-to-use irisCluster resource definition. See the documentation for a full list of features, including easy sharding, mirroring, and configuration of ECP.

IKO 3.3 Highlights:

  • Support for 2021.2 and 2022.1 editions of InterSystems IRIS & IRIS for Health
  • Support for Kuberentes 1.21
  • Deploy common System Alerting and Monitoring (SAM) configurations as part of your irisCluster
  • InterSystems API Manager (IAM) can now also be deployed and managed as part of the irisCluster
  • Automatic tagging of mirror pair active side, so a service can always point to the active mirror member.

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

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!

Hi All,

Been trying to setup a iris 4 health community version along with a webgateway bothing utilizing docker. The documentation seems a little sparse when it comes to configuring each of these to work together, especially when it comes to utilizing the Webgateway to front end the MGMT pages for Irirs 4 Health.

I know there is a github repo that has a docker compose file, but that doesn't see to provide a light on what needs to be configured in order for it to work.

Creating a Custom IRIS Container

I think there have been articles published here before but I'm struggling to find them:

I'd like to be able to create my own customised version of the official IRIS Community Edition Container, eg with Node.js and a number of modules pre-installed. So, for example, can I create my own Dockerfile that begins with something like:

FROM containers.intersystems.com/intersystems/iris-community-arm64:2023.2.0.227.0

and then I can add my own stuff to it?

... or is there another recommended approach?

Any info appreciated

Introduction to Kubernetes

In this article, we will cover below topics:

  • What is Kubernetes?
  • Main Kubernetes (K8s) Components


What is Kubernetes?

Kubernetes is an open-source container orchestration framework developed by Google. In essence, it controls container speed and helps you manage applications consisting of multiple containers. Additionally, it allows you to operate them in different environments, e.g., physical machines, virtual machines, Cloud environments, or even hybrid deployment environments.
