用于kie服务器的配置kie智能路由器

Question

我使用jboss/ kie服务器显示映像来运行kie服务器。我想知道如何配置用于图像文件的kie智能路由器。在执行docker命令时，我将KIE_SERVER_ROUTER作为环境传递：

docker run -p 8180:8080 -d --name kie-server -e KIE_SERVER_ROUTER=http://172.17.0.1:9000 --link jbpm-workbench:kie-wb jboss/kie-server-showcase:latest

但是它不能工作，而且kie服务器不能注册到kie智能路由器。

我克隆https://github.com/jboss-dockerfiles/business-central并在kieserver/showcase/etc中更改start_kie-server.sh文件并修改JBOSS_ARGUMENTS：

JBOSS_ARGUMENTS=" -b $JBOSS_BIND_ADDRESS -Dorg.kie.server.id=$KIE_SERVER_ID -Dorg.kie.server.user=$KIE_SERVER_USER -Dorg.kie.server.pwd=$KIE_SERVER_PWD -Dorg.kie.server.location=$KIE_SERVER_LOCATION -Dorg.kie.server.router=http://172.17.0.1:9000"

并将-Dorg.kie.server.router=http://172.17.0.1:9000"添加到JBOSS_ARGUMENTS中，并成功地注册到kie智能路由器上。但我不修改原始图像，做注册kie服务器。是否存在将kie服务器注册为kie智能路由器的码头容器？

Hello有相同的问题，首先构建kie路由器映像:您需要kie智能路由器jar，您可以从Redhat站点下载它。

####### BASE ############
FROM jboss/base-jdk:8

####### ENVIRONMENT ############
ENV ROUTER_HOME=/opt/jboss \
    KIE_SERVER_ROUTER_REPO_DIR=/opt/jboss \

EXPOSE 9000


####### Kie server router CUSTOM CONFIGURATION ############
ADD kie-server-router.jar $ROUTER_HOME/kie-server-router.jar
ADD start_kie-server-router.sh $ROUTER_HOME/start_kie-server-router.sh


###### SWITCH USER root ######

start_kie-server-router.sh：

#!/usr/bin/env bash


# Default arguments for running the KIE Execution server.
ROUTER_ARGUMENTS="-Dorg.kie.server.router.host=$HOSTNAME -Dorg.kie.server.router.port=9000 -Dorg.kie.server.router.repo=$KIE_SERVER_ROUTER_REPO_DIR -Dorg.kie.server.router.url.external=$ROUTER_HOSTNAME_EXTERNAL"


# Controller argument for the KIE Server router. Only enabled if set the environment variable/s or detected container linking.
if [ -n "$KIE_SERVER_CONTROLLER" ]; then
    echo "Using '$KIE_SERVER_CONTROLLER' as KIE server controller"
    ROUTER_ARGUMENTS="$ROUTER_ARGUMENTS -Dorg.kie.server.controller=$KIE_SERVER_CONTROLLER -Dorg.kie.server.controller.user=$KIE_SERVER_CONTROLLER_USER -Dorg.kie.server.controller.pwd=$KIE_SERVER_CONTROLLER_PWD"
fi


echo "Router arguments '$ROUTER_ARGUMENTS' "


exec java -jar $ROUTER_ARGUMENTS $ROUTER_HOME/kie-server-router.jar
exit $?

构建kie服务器映像，您将在其中使用智能路由器选项克隆这个回购：https://github.com/jboss-dockerfiles/business-central/tree/master/kie-server/showcase

在Dockerfile中编辑

ENV KIE_SERVER_LOCATION http://kie-server:8080/kie-server/services/rest/server

在start_kie-server.sh中添加

# If Kie server router is configured then use it
if [ -n "$KIE_SERVER_ROUTER" ]; then
    echo "Using '$KIE_SERVER_ROUTER' as KIE server router"
    JBOSS_ARGUMENTS="$JBOSS_ARGUMENTS -Dorg.kie.server.router=$KIE_SERVER_ROUTER"
fi

最后船坞组成
