#Containerization

3

Containerization is a lightweight alternative to full machine virtualization that involves encapsulating an application in a container with its own operating environment. 

IRIS offers Durable %SYS Directory as a highly useful feature for working with containers.

Before inventing the wheel once more I'd like to know if a similar feature also exists for Caché / Ensemble.
Official documentation is quite silent about.
Though I have some names in mind that might know more about ( @Luca Ravazzolo ? @Dmitry Maslennikov ? @Eduard Lebedyuk ? )

Just curious how many companies use in their work Docker containers, I mean not only with InterSystems products. And if such companies exist, which of them uses docker and doesn't use it for InterSystems products by some reasons. What are the reasons? For companies which already uses InterSystems in containers, how do you use it? Development environment, testing or even in production ?

And if you don't use but thought about it, what are the reasons which stop you.

As for me, I've been using InterSystems Caché inside a Docker container in some different cases:

dotnet core

Is there an InterSystems supported dotnet core library or community contributed repo on the horizon? At this time we are exploring installing the ODBC driver in our containers but would rather use more robust solution.

greetings Community!

InterSystems Learning Services is working to identify and create libraries of high-quality learning resources for third-party technologies, platforms, and systems that are part of, integrated with, or commonly used with InterSystems products and technologies. we don't create content for these ourselves, but want to support our clients, external and internal, in learning about them and how to use them.

My team works on implementing an Interoperability solution utilizing InterSystems Kubernetes Operator on Red Hat OpenShift container platform.

We are trying to determine how many messages we can process in any given time. We have a Feeder app running in 10 containers sending 50k messages each to a load balancer all beginning at the same time.

Messages are received via HTTPS protocol by webgateway containers.

Interoperability production runs in compute pods with persistent data, journals, and WIJ volumes.

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 -

Hi there, I'm wondering if anyone has run into an issue with <FILEFULL> when building an image from the ISC image? Specifically what's happening in our build is we are pre-loading our codebase into the image to make deployments faster and setting up source control, etc. When loading our libraries however we get hit with a <FILEFULL>. The resource limits on docker are pretty beefy and when observing resources on both the machine and container level we don't hit any issues. Oddly, this only happens when using the ARM64 version.

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.

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?

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?

Does anyone have experience with installing the Arbiter Container using Podman instead of Docker in a Red Hat environment? I was able to pull down the docker image, but unsure what are the next steps as I am confused on how to start the container using Podman and ensure the parameters are set appropriately? Does anyone have the steps that I should take? Should I go through the WRC? Does the WRC have experience using Podman?

Or should I just install the ISC Agent instead of using the Container?

Please and thanks,

Scott Roth

creating a test server

hi, new here, and new to cache and deepsee.

i've been trying to setup a copy of our production server so we can use it for testing/development.

i did a full backup. moved it to the new server. ran the DBREST command. got it to restore but seems like permissions get all messed up. and it just generates a bunch of errors.

is there an easier/better way of doing this?

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

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.

Hey,

I am pretty new to Docker and everything around that. I installed the container image from DockerHub and followed the instructions (https://hub.docker.com/_/intersystems-iris-data-platform/plans/222f869e-567c-4928-b572-eb6a29706fbd?tab=instructions). Everything is working fine except for the part where I want to change the default password.
