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 ? )
I found the need to merge 2 Docker images (e.g. intersystems/iris-community:2020.2.0.199.0 + my home grown NodeJS Image). I found some advice on the Web but no real convincing solution.
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:
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.
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 -
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 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?
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?
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.
I'm interested to hear if folks have experience using Docker containers with Caché instances using ECP. Wondering if there are any special considerations when setting up a distributed application with multiple containers communicating with ECP. Any input is appreciated!
After attending the Intersystems DACH conference in Germany at the end of last November and taking part in a few workshops about containers and microservices I took the plunge and installed Docker on home Windows PC, downloaded IRIS 2018.2 preview and got that up and running. Good stuff and I gave myself a pad on the shoulder at that point.
For a solo developer developing web applications what will be the best technology to use IRIS or Studio with cache database and containers for deployment
How to programmatically setup docker-compose file to have IRIS container with OS authentication enabled? And have the following while entering the terminal:
I am trying to experiment the Docker container in our development environment. I have successfully build an image and running the container. When I access the CSP portal home page ( http://<host-ip>:57772/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS), I am getting the following error:
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.
When deploying IRIS in a container, what are recommendations for permitting users terminal access? There is docker exec -it, but that does not work from a user's workstation where - in the old deployment model - they would connect to the server over ssh using Putty and open a terminal session from there.
I'll start with an apology as I am trying to wrap my head around the architecture of how InterSystems IRIS database management works. I am attempting to connect to the platform remotely through say a JDBC or ODBC connection in order to run queries, searches (through SQL statements) on my laptop and was trying to understand whether this would be possible? It is possible to setup an inbound client connection and wanted to better understand the architecture of how the database association works for IRIS database management. Does it use it's own internal SQL database or are we able to connect to our own database and which databases are certified to run against the platform?
