Docker with wildfly-jar-maven-plugin

[Adriano Aguiar]

I'm trying to build a system in Docker, but it doesn't respond. From the log, I see that when starting, it connects to the database and does not show any errors. However, I don't know if it needs any additional configuration. I'm using the wildfly-jar-maven-plugin and when I run the jar directly, it works normally. However, when placing the jar inside Docker, it does not respond. I would like to know if there is anything else that needs to be done. Below are docker configurations:

Dockerfile:

FROM openjdk:17-jdk-slim-buster

RUN mkdir -p /opt


COPY target/*.jar /opt/comercial-nfe-bootable.jar
EXPOSE 8080
CMD java -Xms${JAVA_XMS:-512m} -Xmx${JAVA_XMX:-3072m} -jar /opt/comercial-nfe-bootable.jar

version: '3.1'

services:
  api:
    image: comercial-2apex
    build: .
    environment:
      - POSTGRESQL_USER=postgres
      - POSTGRESQL_PASSWORD=${POSTGRES_PASSWORD:-12345678}
      - POSTGRESQL_DATABASE=adriano
      - POSTGRESQL_DATASOURCE=comercialDS
      - POSTGRESQL_SERVICE_PORT=5432
      - POSTGRESQL_HOST=192.168.18.78
    ports:
      - 8080:8080
   
    networks:
      - comercial-2apex-network
     
    container_name: comercial-2apex
   
networks:
    comercial-2apex-network:
      driver: bridge

Hi Adriano,

I suspect that it is a network issue. By default the server will listen on 127.0.0.1. Could you check your start log?

You can do it in 2 ways:

* Add the <cloud/> element to the plugin configuration

* Or, in your Dockerfile adds -b=0.0.0.0 when launching the jar

Hope that helps.

Thanks Jean, I managed to solve it by running this script: /interface=public:write-attribute(name=inet-address,value=0.0.0.0)

Adriano,

you found a nice alternate solution. To give context to readers, the WildFly Bootable JAR Maven Plugin allows you to execute CLI scripts to fine tune your config once the server has been provisioned and 

prior to creating the executable jar file. You can find information in the Bootable JAR documentation: http://docs.wildfly.org/bootablejar/#wildfly_jar_configuring_build_cli

Thanks for the link, that's where I was able to see the solution and now my system is perfect using wildfly Multi Tenant
