Error to load IAM image

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:

This is a 10-minute simple step-by-step guide on how to quickly set up various flavors of HealthShare docker containers from scratch on a Win10 laptop. 

For example, we can build a couple of  HealthShare "global edition vs UK Edition" demos as shown below.  

There are a couple of frequently asked questions from HealthShare colleagues and partners:

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 ?  )

Hi Developers!

Suppose I have a project where I want to build an IRIS container with two different dockerfiles depending on goals.  How can I make it?

The issue is that docker-compose is looking for the file with name 'dockerfile'

Are there any #IF constrations in a dockerfile syntax? 

Commenting works but sometimes it's more than one line.

OAuth server to be deployed on the IRIS learning cloud platform. Clients - one on the other instance of the learning IRIS server, the other client locally on my computer in the container docker.

Both clients get a seemingly correct link (through ##class(%SYS.OAuth2.Authorization).GetAuthorizationCodeEndpoint()) to the login request form:

Hi developers!

Every day coding with IRIS and docker I call the following 3 commands in VSCode terminal. Always the same for any projects:

docker-compose build   ; to build the container

docker-compose up -d   ; to run the IRIS in container

docker-compose exec iris iris session iris ; to open the IRIS terminal

Is there any way to map the key sequence which will type me the rest?

Docker container error

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 guys!

Portrait of  Madame X, Gustave Caillebotte.

One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.

Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.

The trick is how you transfer an array to work with into a function. 

One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator. 

Below you can find a very simple example which illustrates the thing.

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 its 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.

Cache docker image

Hello all,

I am having some issues creating a docker image with a fresh cache installation. The error that I am getting right now is that gzip is required for a cache installation, but was not found in my system. Even though, this is shown as installed in the base centos 7 image. My host machine is Windows 10 using the latest docker version.

Here is my dockerfile, its simple:

I am just recently announced my project isc-tar. But sometimes it is not less interesting what’s behind the scene: how it was built, how it works and what happens around the project. Here is the story:

  • How to develop this project
  • How to test it
  • How to release new versions for publishing
  • And finally how to automate all above
  • Continuous integration

So, I would like to tell all about it.

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.

Docker-compose default network conflicts

I recently had to diagnose a networking problem I was having when attached to our corporate network.   I was seeing an unknown bridge network being defined that shared the same IP address space as the company network thus blocking access to company resources.  This bridge network was separate from the Docker0 bridge network which the docker engine sets up.  Docker was configured with a bip (bridge ip) address to prevent docker form using an address space that create a conflict.
