One of my colleagues at InterSystems encountered an unexpected issue when running InterSystems IRIS on a Macintosh in a container using Docker for Mac.  I’d like to share what we found, so you might avoid running into similar issues.

I wanted to write it as a comment to article of @Evgeny ShvarovEvgeny ShvarovEvgeny 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.

InterSystems supports use of the InterSystems IRIS Docker images it provides on Linux only. Rather than executing containers as native processes, as on Linux platforms, Docker for Windows creates a Linux VM running under Hyper-V, the Windows virtualizer, to host containers. These additional layers add complexity that prevents InterSystems from supporting Docker for Windows at this time.

The last time that I created a playground for experimenting with machine learning using Apache Spark and an InterSystems data platform,  see Machine Learning with Spark and Caché, I installed and configured everything directly on my laptop: Caché, Python, Apache Spark, Java, some Hadoop libraries, to name a few. It required some effort, but eventually it worked.

Hi Community!

We're pleased to announce that that InterSystems IRIS Community Edition is available on the Docker Store! InterSystems IRIS Community Edition is the no-cost developer edition designed to lower the barriers to entry to get started with IRIS. Now that it is listed on the Docker Store, running an IRIS Community instance is as easy as -

Dear team,

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:

Hi Community!

I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects  check any on Open Exchange.

What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?

We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.

So every developer performs the following:

  1. Check out the code from repo
  2. Install/Run local IRIS installation
  3. Create a new namespace/database for a project
  4. Import the code into this new namespace
  5. Setup all the rest environment
  6. Start/continue coding the project 

If you dockerize your repository this steps line could be shortened to this 3 steps:

  1. Check out the code from repo
  2. Run docker-compose build 
  3. Start/continue coding the project 

Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.

You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!

This is a continuation of my story about the development of my project isc-tar started in the first part.

Just having tests is not enough, it does not mean that you will run tests after all changes. Running tests should be automated, and when you cover all your functionality with tests, everything should work well after any change in any place.  And Continuous Integration (CI) helps to keep the code and deployment procedure with as fewer bugs as possible and automates the routine procedures, like publishing releases.

I use GitHub to store the source code. And some time ago GitHub started to work on their own CI/CD platform and named it GitHub Actions. It is not widely available, yet. You have to be signed as a beta tester for this feature, as I did. GitHub Actions uses quite a different way how to deal with a build workflow. What is important that Github Actions allows to use docker, and it’s quite easy to customize available actions. And interesting that GitHub Actions is really much bigger than any classic CI like we have in Travis, Circle or Gitlab CI and so on. You can find more in the official documentation.

Hi Community!

When you run  IRIS container out-of-the-box and connect to it via terminal e.g. with:

docker-compose exec iris bash

You see something like:

root@7b19f545187b:/opt/app# irissession IRIS

Node: 7b19f545187b, Instance: IRIS

Username: ***

Password: ***

USER>

And you enter login and password every time.

How to programmatically setup docker-compose file to have IRIS container with OS authentication enabled? And have the following while entering the terminal:

root@7b19f545187b:/opt/app# irissession IRIS

Node: 7b19f545187b, Instance: IRIS

USER>

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

  • Git 101
  • Git flow (development process)
  • GitLab installation
  • GitLab Workflow
  • Continuous Delivery
  • GitLab installation and configuration
  • GitLab CI/CD

In the previous article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software. Still, our focus was on the implementation part of software development, but this part presents:

  • GitLab Workflow - a complete software life cycle process - from idea to user feedback
  • Continuous Delivery - software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently.

The Amazon Web Services (AWS) Cloud provides a broad set of infrastructure services, such as compute resources, storage options, and networking that are delivered as a utility: on-demand, available in seconds, with pay-as-you-go pricing. New services can be provisioned quickly, without upfront capital expense. This allows enterprises, start-ups, small and medium-sized businesses, and customers in the public sector to access the building blocks they need to respond quickly to changing business requirements.

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.

Everybody has a testing environment.

Some people are lucky enough to have a totally separate environment to run production in.

InterSystems is adopting a new approach to releasing InterSystems IRIS.  This blog explains the new release model and what customers should expect to see.  We laid this out at Global Summit at the end of the InterSystems IRIS roadmap session  and have received a lot of positive feedback from customers.

With this new model we offer two release streams:

1) An annual traditional release that we call EM (for Extended Maintenance)

2) A quarterly release that is tagged CD (for Continuous Delivery) and will be available only in a container format.

Containers

With the launch of InterSystems IRIS Data Platform, we provide our product even  in a Docker container. But what is a container?

The fundamental container definition is that of a sandbox for a process.  

Containers are software-defined packages that have some similarities to virtual machines (VM) like for example they can be executed. 

Containers provide isolation without a full OS emulation. Containers are therefore much lighter than a VM.

Google Cloud Platform (GCP) provides a feature rich environment for Infrastructure-as-a-Service (IaaS) as a cloud offering fully capable of supporting all of InterSystems products including the latest InterSystems IRIS Data Platform. Care must be taken, as with any platform or deployment model, to ensure all aspects of an environment are considered such as performance, availability, operations, and management procedures.  Specifics of each of those areas will be covered in this article.

Hello!

Checking to see if anyone has experience with deploying their Docker containers on a platform like OpenShift (or vanilla Kubernetes)?

If you have, do you have any guidance or lessons-learned?  Is this even something feasible with a HealthShare/Ensemble instance?

Hello!

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!

Hi All,

Who, in the age of digital transformation, doesn't want to reap more benefits out of any process, procedure, and resource we have? At InterSystems Solution Developers Conference (part of InterSystems Global Summit 2018) we will have sessions on how to improve the way applications are built with modern tools like Docker containers, Gitlab, Circle CI, Travis, etc., how continuous integration and continuous delivery (CI/CD) processes can help us deliver more value quickly to the end-user, and how we can start thinking about modernizing traditional applications.
