• 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.

What problems does it solve?

What is the point of having a dedicated registry if it does not work properly most of the time?

I am fairly new to using Docker, and instead of trying to get IIS, a Web Gateway, and Docker desktop working within my Windows environment, I thought I would try running it in a WSL2 Ubuntu environment since this is similar to how use it on my server. I have installed Apache and the Web Gateway on my WSL2 Ubuntu.

I went through Apache Web Gateway with Docker | InterSystems Developer Community however that is already bundled and requires TLS certificate setup which I don't care about since this is running locally on my machine.

Hi VSCode users!

Just want to check with you, is this settings.json file ideal enough if I:

1. Want VSCode to connect to IRIS in docker?

2. Want to use VSCode SQL Tool?

The connection settings file:

{
    "files.associations": {
    
        "Dockerfile*": "dockerfile",
        "iris.script": "objectscript"
      },
    "objectscript.conn" :{
      "ns": "IRISAPP",
      "username":"_SYSTEM",
      "password": "SYS",
      "docker-compose": {
        "service": "iris",
        "internalPort": 52773
      }
    },
    "sqltools.

As most of you probably already know, since approximately the end of 2022 InterSystems IRIS included the columnar storage functionality to its database, well, in today's article we are going to put it to the test in comparison to the usual row storage.

Columnar Storage

What is the main characteristic of this type of storage?

Can anyone give me a hint about this error?

I can compile sources following this approach, create a container and so on, but for example in specific commands to run test, I get the error.

ERROR #6063: Memory allocation for the Monitor failed

I want to address the nasty problems about reading a flat text in ASCII, UTF*
explicitly excluding HTML, EBCDIC, and other encoding.
According to Wikipedia there are at least 8 variations of control characters.

• CR+LF is typical for Windows
• LF is typical for the Linux/UNIX world
• CR is Mac's favorite

As you can deduct from the names the inspiration comes from mechanical typewriters.

In IRIS* similar as in Caché or Ensemble or .

Hey Community,

Hi folks!

Sometimes building an images via docker-compose.yml can take significant time.

And often after a minute or two of waiting it turns out that ports listed in docker-compose are busy and you need to start building process again with different ports or to turn down processes that took it.

Is there a way to check ports listed in docker-compose BEFORE starting the image baking process?

How do you deal with this problem?

Hi Community

This document mainly enriches the content of the previous article and introduces the use of the application.

Perhaps you have already read the previous article, but I still want to say,
After completing the initialization operation (including model creation and training), the Fhir HepatitisC Predict application then predicts HepatitisC

First

You need to input some information on the application, of course, only the results of some checks, not including privacy data.

Hello,

How can I send a request via a SOCKS5 proxy in IRIS, using, for example, EnsLib.REST.Operation?

Background

I need to access APIs inside my corporate network, to which I don't have direct access from my home office. I've set up a SOCKS5 proxy via SSH on my host machine like this:

ssh -D 9999 server.corporate.com

I can then make requests with curl to the APIs I need:

curl -x socks5h://localhost:9999 https://api.corporate.com/api/some/endpoint

And I receive a response. Simple!

Also, inside the containerized IRIS, I can execute the request:

curl -x socks5h://host.docker.internal:9999 https://api.

Processing FHIR resources with FHIR SQL BUILDER to predict the probability of developing hepatitis C disease

With the development of technology, the medical industry is also constantly advancing, and humans often pay more attention to their own health,
By learning and processing datasets through computers, diseases can be predicted.

I downloaded containers.intersystems.com/intersystems/healthshare_providerdirectory:2023.2 to evaluate, however when I try to run the container it keeps

exiting. 

>docker run --name providerdirectory --user=irisowner --env=ISC_DATA_DIRECTORY=/intersystems/irisdata --runtime=runc -d containers.intersystems.com/intersystems/healthshare_providerdirectory:2023.2

I keep getting the following, and I am not sure why...

2024-01-1720:36:20 [INFO] Executing command /home/irisowner/irissys/startISCAgent.sh 2188...
2024-01-1720:36:20 [INFO] Writing status to file:

I have been struggling with a docker run command that kept crashing, the error message was too generic to point me to the right direction.

Since the container is shut down after the failure, I was unable to login to it in order to figure out the problem.

I had to run the container in a way that I'll be able to log into it before it crashed, so I found the adding  -u false prevents the docker run command to run the iris session IRIS and the container stayed up and running.

I am trying to get data out of a cache backup. I am completely new to Intersystems Cache.
I got a docker image of Cache from this post: 
I want to get the data from my backup into this docker image. First, I need access to a gui and a cli, then I need some instructions or documentation for actually pulling in the backup data.
Thanks! This is all new, so pardon my lack of knowledge here. If I can provide any more information let me know.

Hello everyone,

I'm currently conducting tests using the docker image intersystemsdc/irishealth-ml-community:latest. I'm accessing the Linux terminal and attempting to utilize the superuser functions, but I'm encountering an issue with the password. Could someone assist me, please?

Hi Community,

In this article, we will learn the below topics listed below:

1. What is Docker?
2. Some of the Docker benefits
3. How does Docker work?
4. Docker Image
5. Docker Container
6. Docker Image repository
7. InterSystems's Docker image repository
8. Docker Installation
9. Docker Basic Commands
10. Running IRIS community edition by using docker
11. Docker Desktop GUI

So Let's start.

1. What is Docker?

Docker is Virtualization software that makes developing and deploying applications very easy.

Windows Subsystem for Linux (WSL) is a feature of Windows that allows you to run a Linux environment on your Windows machine, without the need for a separate virtual machine or dual booting. 

WSL is designed to provide a seamless and productive experience for developers who want to use both Windows and Linux at the same time**.

WSL 2 is the default distro type when installing a Linux distribution. WSL 2 uses virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). Linux distributions run as isolated containers inside of the WSL 2 managed VM.

I'm trying to install the Inter System IRIS data platform in windows and I'm not able to download the installer file. Some one can help me with this.

Please look at the below image for the reference for the error I'm facing 

And also I'm looking for the docker version of the IRIS, but here also I'm not able to identify the IMAGE for the same. Please look into the below image.

Thanks.

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!

Hello,

In response to the infrastructure needs of our company's service, I've created a small API that sends SNMP queries to InterSystems to visualize relevant data for retrieval when the infrastructure implements monitoring.

However, I'm experiencing a timeout issue when attempting to collect information using an SNMP walk. Here is the code for my API's SNMP service:

import snmp from"net-snmp";

const options = {
    port: 161,
    retries: 4,
    timeout: 3000,
    transport: "udp4", // Uniquement udp4 et udp6 possible
    trapPort: 162
};

const oids = [ "1.3.6.1.4.1.16563.4.1.15.1.

I'm trying to run IRIS for Health Community Edition container on Mac (Apple chip) as follows

docker run --name iris -d --publish 1972:1972 --publish 52773:52773 --volume /<volume-path-on-host>:/<volume-name-in-container> --env ISC_DATA_DIRECTORY=/<volume-name-in-container>/<durable-directory> containers.intersystems.com/intersystems/irishealth-community-arm64:latest-cd

but it will error out to start

I'm using a customised IRIS Community Edition Docker Container: Node.js has been added and the Native API for Node.js directory moved to a node_modules folder in /home/irisowner.

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

Hi,

I am using the container image 2023.1 and am hitting a max total db size error.  However, this post indicates that the issue should have been resolved in Community edition 2019.3

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.

We continue with the series of articles based on the QuinielaML application.

In today's article I will describe how to work with the Embedded Python functionality available in InterSystems products.

Embedded Python allows us to use Python as a programming language within our productions, being able to take advantage of all the features available in Python. Here you can expand information about it.

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.
