Eureka Demo

Use the eureka service to register the devbox-sante launched by users

With two workstations

A first use case eurekaservice as a directory server for workstations

!include https://bitbucket.org/devbox-sante/plantuml/raw/current/themes/theme-devbox-sante.puml


node "EurekaServer" {
   [EurekaService:9998] as eureka
}

node "WorkstationWithCps" {
   [DevBox-Sante:1000x] as devbox1  DEVBOX_COLOR
   [CPS reader] as cps
}
devbox1 -l-> eureka : register
devbox1 -- cps

Install EurekaServer

install the eureka service on a machine : https://clients.devbox-sante.fr/installer/client/id/DEV/DevBoxSante-client-dev-windows-x64-eureka-4.x.exe
during the installation pick a port number for Eurekas : 9998 for example
after the installation stop all devbox-sante running (except the eureka service)
check that eureka is running on localhost with the installation port: http://localhost:9998/users and no process is running
get its ip and check access from another workstation : http://192.168.1.26:9998/users

eureka users

Install Workstation with CPS

install on the workstation with the CPS card reader, the devbox-sante with one of the installer, preferably the one without eureka. If you use the installer with Eureka disable the service :
configure the devbox-sante with the following entries (make sure that the devbox-sante point to the eureka service) :

spring:
  profiles.active:
  ...
  - "EUREKA"

devbox-sante:
...
  eureka:
    service.url: "http://192.168.1.26:9998"

Run

Prerequisite, the eureka service is running on the EurekaServer machine.

If there is any DevBoxSante running before stop it
execute the DevBoxSante-client-dev.exe to launch with the right configuration
check on the log that the devbox-sante registered to the eureka service :

2023-11-22 17:30:13.964  INFO 51952 --- [           main] f.d.clients.eureka.DbxEurekaRestClient   : Post http://192.168.1.26:9998/user : lfo, 192.168.1.12, 10025, null

As a result on the eureka users list and more specifically with the endpoint /user/lfo :

registered on windows

Considering the result of this endpoint, you know where to access the right DevBoxSante for the user lfo :

dbx user lfo

Case 2 : launch the DevBox-Sante from a web-context :

stop previously DevBox-Sante launched
from the browser launch the devbox-sante with providing that url : devboxsante-client-dev://config?server.port=10101&sessionID=webUser1

eureka web users

Then, in every workstation a DevBox-Sante should be launched with a different user sessionID. Then you can do the following mapping :

One user sessionId = One IP:PORT = one CPS card reader

On Citrix or RDP Server

On Citrix or RDP Server everything is launched on the same host, so everything is available on localhost, but with different http ports.

!include https://bitbucket.org/devbox-sante/plantuml/raw/current/themes/theme-devbox-sante.puml

node "Serveur RDP" {
    [EurekaService:9998] as eureka
  [DevBox-Santé1:10001] as devbox1 DEVBOX_COLOR
  [DevBox-Santé2:10002] as devbox2 DEVBOX_COLOR
}

node "Workstation user 1" {
   [USB ports of CPS card reader 1] as usb1
}
node "Workstation user 2" {
   [USB port of CPS card reader 2] as usb2
}
devbox1 -- usb1 : map USB pors ts
devbox2 -- usb2 : map USB ports
