COVID-19 Analytics on InterSystems IRIS

Hi colleagues!

Every day Johns Hopkins University publishes new data on coronavirus COVID-19 pandemic status.

I built a simple InterSystems IRIS Analytics dashboard using InterSystems IRIS Community Edition in docker deployed on GCP Kubernetes which shows key measures of the disease outbreak.

This dashboard is an example of how information from CSV could be analyzed with IRIS Analytics and deployed to GCP Kubernetes in a form of InterSystems IRIS Community Edition.

Added the interactive map of the USA:

The next dashboard shows the timeline:

And can be filtered by country. E.g. here is in the USA:

The source code of the application is available on Open Exchange.

How does it work?

Demo runs using InterSystems IRIS Community Edition docker container and exposes InterSystems IRIS BI dashboards using DeepSee Web representation layer via MDX2JSON REST API. Its deployed on GCP and operates using Google Kubernetes Engine (GKE).

How it was developed 

The data is taken from the Johns Hopkins repository in CSV form.

Classes, cubes, and initial pivots were generated via Analyzethis module, thanks @Peter Steiwer!

Import method then was introduced using the CSVTOCLASS method, thanks @Eduard Lebedyuk!

Dashboards are rendered with DeepSee Web (DSW) module.

IRIS BI artifacts (pivots, dashboards) were exported by ISC.DEV module:

IRISAPP> d ##class(dev.code).workdir("/irisdev/app/src")

IRISAPP> d ##class(dev.code).export("*.dfi")

The code has been developed using VSCode ObjectScript, thanks @Dmitry Maslennikov.

Building docker image for development and deployment
All the deployment sits in Dockerfile. With Dockerfile we build an image with data, web apps and modules installed and properly setup and then we deploy the image to GCP Kubernetes.

This Dockerfile is a modified version of this Template Dockerfile which is described very well in this article.

All the preliminary steps are being done in iris.script file:

Here we install DeepSee Web.

zpm "install dsw"

This enables IRIS Analytics (DeepSee) for /csp/irisapp web app:

do EnableDeepSee^%SYS.cspServer("/csp/irisapp/")

This code is needed to make the analytics web app be available without credentials:

  zn "%SYS" 
  write "Modify MDX2JSON application security...",! 
  set webName = "/mdx2json" 
  set webProperties("AutheEnabled") = 64 
  set webProperties("MatchRoles")=":%DB_IRISAPP" 
  set sc = ##class(Security.Applications).Modify(webName, .webProperties) 
  if sc<1 write $SYSTEM.OBJ.DisplayError(sc)

And here in Dockerfile this command helps to set DSW configuration.

COPY irisapp.json /usr/irissys/csp/dsw/configs/

Deployment to Kubernetes

The deployment procedure is being processed by Github Actions - and this workflow handles it on every commit to the repository.

Github workflow uses Dockerfile we built on a previous step along with Terraform and Kubernetes settings. 

The procedure is identical to the one described in this article by @Mikhail Khomenko.

How to run and develop it locally

You are very welcome to run, develop and collaborate with this project.

To run it locally using docker do:

Clone/git pull the repo into any local directory

$ git clone https://github.com/intersystems-community/objectscript-docker-template.git

Open the terminal in this directory and run:

$ docker-compose build

3. Run the IRIS container:

$ docker-compose up -d

Once the container is built up and running open the application on:

localhost:yourport/dsw/index.html#/irisapp

How to Develop

This repository is ready to code in VSCode with the ObjectScript plugin. Install VSCode, Docker, and ObjectScript plugin and open the folder in VSCode.

How to Contribute
