JBoss Data Grid Visualizer Demo

JBoss Data Grid Demo running on Docker

This demo is based on previous work, see:

• JDG Visualizer Demo https://github.com/infinispan/visual
• Hot Rod Demo https://github.com/saturnism/hotrod-demo

There are two Docker containers:

• A JBoss Data Grid container, running four Data Grid instances
• A JBoss Enterprise Application Platform, running the visualizer application

1. System Requirements

• Docker
• Maven

2. Required external files

Before building the containers, you will have to download the following products:

• JBoss Data Grid 6.4
• JBoss Enterprise Application Platform 6.3

And place them in the corresponding directories, jdg-container and eap-container.

3. Building the containers

3.1 JBoss Data Grid Container

cd jdg-container
docker build -t jdg .
docker run -d --name jdg -p 8081:8081 -p 9991:9991 -p 11223:11223 -p 8082:8082 -p 9992:9992 -p 11224:11224 -p 8083:8083 -p 9993:9993 -p 11225:11225 -p 8084:8084 -p 9994:9994 -p 11226:11226 jdg

After the container has been built and run, you can start it and stop it by its name:

docker stop jdg
docker start jdg

3.2 JBoss EAP container

docker build -t eap .
docker run -d --name eap --link jdg:jdg -p 8080:8080 -p 9990:9990 eap

After the container has been built and run, you can start it and stop it by its name:

docker stop eap
docker start eap

4 Populating data

To populate the grid with data we are going to build and execute the hotrod-demo application:

git clone https://github.com/mpbravo/hotrod-demo.git
cd hotrod-demo
mvn -s example-settings.xml clean package
./data.sh

5 Visualizing the cache

Open a browser and type http://localhost:8080/jdg-visualizer

6 Stopping and starting Data Grid nodes

Get into the container running Data Grid nodes:

docker exec -i -t jdg bash

Execute supervisorctl in the container:

[root@1bdf8fef169f /]#supervisorctl

Check process status:

supervisor> status
jdg1                             RUNNING    pid 1700, uptime 0:02:42
jdg2                             RUNNING    pid 1897, uptime 0:01:08
jdg3                             RUNNING    pid 1479, uptime 0:03:00
jdg4                             RUNNING    pid 8, uptime 0:08:25

With Supervisor you can stop and start the different Data Grid nodes and see the results in the web application.
