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 want to share a personal project that started with a simple request at work: 

Is it's possible to know how many Caché licenses we are using? 

Reading other articles here in the community, I found this excellent article by  David Loveluck

Last time we deployed a simple IRIS application to the Google Cloud. Now we’re going to deploy the same project to Amazon Web Services using its Elastic Kubernetes Service (EKS).

We assume you’ve already forked the IRIS project to your own private repository. It’s called <username>/my-objectscript-rest-docker-template in this article. <root_repo_dir> is its root directory.

Before getting started, install the AWS command-line interface and, for Kubernetes cluster creation, eksctl, a simple CLI utility. For AWS you can try to use aws2, but you’ll need to set aws2 usage in kube config file as described here.

Hot on the heels of the QEWD-JSdb announcement, QEWD-baseline provides a ready-to-run baseline environment for developing REST APIs.

The QEWD-baseline repository (https://github.com/robtweed/qewd-baseline) includes a fully-detailed tutorial on how to build RESY APIs using QEWD and the QEWD-JSdb database (running of course on IRIS).

Included in the tutorial is:

I want to add ports 9100 and 9101 in addition to 52773. I read on docker container documentation that this is not possible on a already ran image. Currently it starts the google cloud IRIS health container automatically without me able to specify the additional ports. How can I add ports to Google cloud IRIS Health container?

Hi Developers!

For those who want to participate in the Advent of Code 2019 and code with ObjectScript in IRIS, I created a very simple but handy Github Template.

Use the green button

to copy template in your own repo, clone the repo and run in the repo folder:

docker-compose up -d

you will get InterSystems IRIS 2019.4 Community Edition running with the template classes to load input data from files and Day1 solution.

This is also set up to start crafting solutions of Advent of Code 2019 and edit, compile and debug ObjectScript with VSCode addon.

Happy coding with Advent of Code 2019!

¡Hi everybody!

As you likely are aware, the new version of InterSystems IRIS for Health (I4H) it's already available in Docker Hub. It's the Community version and is free and fully functional. There have been comments about it in other articles and posts,... so today I won't add anything about features. Here I want to explore "the mistery about the disappearance, or better, absence of our persistent data when we run a container with the durable option"  (I didn't find a terrifying font to emphasize the thriller... post editor is not terrific for styling smiley ) .

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.

Hi Developers!

Often I find questions on how to install IRIS, connect to IRIS from IDE, setup the environment, compile, debug, maintain the repository.

Here below possibly the shortest way to set up all the environment and start development with ObjectScript on InterSystems IRIS.

Prerequisites

Make sure you have Git, Docker, and VSCode installed

Install Docker and ObjectScript extensions into VSCode

Sign in or Create an account on Github

Here we go!

Hi Developers!

Suppose you want to create your ObjectScript library to be distributed via ObjectScript Package Manager. And there is an obvious question: what is the naming convention on the packages and class names?

Hi Developers!

Those who use Dockerfile to work with InterSystems IRIS often need to execute several lines of ObjectScript.  For me, this was a game of "escaping this and that" every time just to shoot a few commands on ObjectScript to IRIS. Ideally, I'd prefer to code ObjectScript without any quotes and escaping.

Recently I found a nice "hack" on how this could be improved to exactly this state. I got this from @Dmitriy Maslennikov's repo and this lets you use Objectscript in a way as you would type it in IRIS terminal.

Here is what you have in dockerfile:

///
COPY irissession.sh /
SHELL ["/irissession.sh"]
RUN \
  do $SYSTEM.OBJ.Load("Installer.cls", "ck") \
  set sc = ##class(App.Installer).setup()
# bringing the standard shell back
SHELL ["/bin/bash", "-c"]
CMD [ "-l", "/usr/irissys/mgr/messages.log" ]
///

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 wanted to write it as a comment to article of @Evgeny Shvarov . But it happens to be so long, so, decided to post it separately.

Image result for docker clean all images

I would like to add a bit of clarification about how docker uses disk space and how to clean it.  I use macOS, so, everything below, is mostly for macOS, but docker commands suit for any platform.

Hi folks,

I started to play with docker and InterSystems products, it's amazing, but I got the error when try to load the IAM-0.34-1-1.tar.gz image to docker:


[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker load -i IAM-0.34-1-1.tar.gz
open /var/lib/docker/tmp/docker-import-547148651/IAM/json: no such file or directory

Bellow docker and docker-compose version:

[root@CONF-RHEL-DOCKER-IRIS-API admconf]# docker --version
Docker version 19.03.2, build 6a30dfc

Hi guys!

Was coding today with InterSystems IRIS in a docker container and decided to share with you the commands you may find useful in everyday coding.

# docker-compose build

command to build a container. Remember, it is useful if you have dockerfile in the repo.

if the build is successful call the following to launch it:

# docker-compose up -d

Find IRIS management portal on:

localhost:port/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS

where the port is what you set in docker-compose.yml - 52775 in this case.

Run the following if you want to launch a terminal session inside IRIS container:

# docker-compose iris iris session iris

gfhj gj 


sdfdsfsdf





USER>

And run the following to shut down the container:

# docker-compose down

Hi Developers!

InterSystems Package Manager (ZPM) is a great thing, but it is even better if you don't need to install it but can use immediately.

There are several ways how to do this and here is one approach of having IRIS container with ZPM built with dockerfile.

I've prepared a repository which has a few lines in dockerfile which perform the download and install the latest version of ZPM. 

Add these lines to your standard dockerfile for IRIS community edition and you will have ZPM installed and ready to use.

To download the latest ZPM client:

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 @Dmitriy Maslennikov  ?     @Eduard Lebedyuk ?  )
