システム間アイリスを用いたCOVID - 19解析

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 .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.

So I will stop only on new parts. 

17 COPY  data files

here we copy CSV files from data folder to the container

set pfile = "/opt/irisapp/files/covid-"_$tr($zd($h-1),"/","-")_".csv", rc=0 \
  do ##class(AnalyzeThis.Generated.covid03162020).Import(,pfile,",", ,1,.rc) \
  write "imported records: "_rc \
  do ##class(%DeepSee.Utils).%BuildCube("covid03162020") \

This code imports the latest data and builds a cube.

zpm "install dsw" \

Here we install DeepSee Web.

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

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

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)

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

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

And this command helps to set DSW configuration.

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 .Khomenko.
