-e POSTGRES_USER=postgresUser \
-e POSTGRES_PASSWORD=postgresPW \
-e POSTGRES_DB=postgresDB \
-d postgres
Extract keycloak-20.0.5.zip
cd keycloak-20.0.5
Start keycloak in dev mode listening on port 8081
./bin/kc.sh start-dev --http-port=8081

Unzip jboss-eap-7.4.0.zip
cd jboss-eap-7.4/jboss-eap-7.4
Create the folder modules/org/postgresql/main
mkdir -p modules/org/postgresql/main
Download the postgres jdbc driver from https://jdbc.postgresql.org/download/ e.g. https://jdbc.postgresql.org/download/postgresql-42.5.4.jar
Copy postgres jar file to modules/org/postgresql/main
create module.xml -- ensure the filename matches the filename downloaded in the previous step
cat <<EOF > modules/org/postgresql/main/module.xml
<?xml version="1.0" encoding="UTF-8"?>

Start JBoss EAP 7.4 in full high availability mode
From the jboss-eap-7.4 folder run:
./jboss-eap-7.4-2/bin/standalone.sh -c standalone-full-ha.xml -Djboss.node.name=node1
In another terminal, start the jboss cli, from the jboss7.4 installation folder run
./bin/jboss-cli.sh --connect
Run the following commands:
/subsystem=datasources/jdbc-driver=postgresql:add(driver-name=postgresql,driver-module-name=org.postgresql)
data-source add --name=CoolstoreDS --jndi-name=java:jboss/datasources/CoolstoreDS --driver-name=postgresql --connection-url=jdbc:postgresql://127.0.0.1:5432/postgresDB --user-name=postgresUser --password=postgresPW
jms-topic add --topic-address=topic.orders --entries=topic/orders
/subsystem=messaging-activemq/server=default:write-attribute(name=cluster-password, value=password)
From the root of this repo, run:
mvn package
Set the JBOSS_HOME env variable e.g.
export JBOSS_HOME=~/jboss-eap-7.4/jboss-eap-7.4
Run the jboss cli:
$JBOSS_HOME/bin/jboss-cli.sh
Run the following command to deploy the application:
deploy ./target/ROOT.war
Navigate to http://127.0.0.1:8080
From the coostore, click on "Sign in" in the top right
Login with the user credentials created on Keycloak, e.g. user1
You should now be able to complete the checkout process.
Make a copy of the jboss-eap-7.4/jboss-eap-7.4 e.g jboss-eap-7.4/jboss-eap-7.4-2
Within the jboss-eap-7.4 folder you should now see jboss-eap-7.4 and jboss-eap-7.4-2
In the jboss-eap-7.4-2, remove the contents of standalone/data/activemq
From the jboss-eap-7.4 folder run:
./jboss-eap-7.4-2/bin/standalone.sh -c standalone-full-ha.xml -Djboss.socket.binding.port-offset=100 -Djboss.node.name=node2
Open up two terminals in the jboss-eap-7.4 folder
Run:
tail -f jboss-eap-7.4/standalone/log/server.log
in one terminal and
tail -f jboss-eap-7.4-2/standalone/log/server.log
in the other
If you perform a test checkout of an item, you should see both nodes processing the messages in the logs e.g.
