一：简介

dubbo-admin是dubbo框架的管理平台。

二: 创建继续镜像

Dockerfile

FROM fangjipu/jdk8:8

RUN yum -y install epel-release

RUN mkdir /app

ADD tomcat8 /app/tomcat8

ADD docker-entrypoint.sh /app

EXPOSE 8080 8443

WORKDIR /app

ENTRYPOINT ["sh", "docker-entrypoint.sh"]

入口文件：docker-entrypoint.sh

#!/bin/bash


if [[ -z $ZK ]]
then
  ZK=‘zk:2181‘
fi

if [[ -z $root_passwd ]]
then
  root_passwd=‘123456‘
fi

sed -i -r "s%([0-9]+\.){3}[0-9]+\:[0-9]+%${ZK}%g" /app/tomcat8/webapps/admin/WEB-INF/dubbo.properties

sed -i -r "s%dubbo.admin.root.password=%dubbo.admin.root.password=${root_passwd}%g" /app/tomcat8/webapps/admin/WEB-INF/dubbo.properties

cd /app/tomcat8/bin

sh catalina.sh run

三：启动镜像

启动镜像时，我们可以通过变量ZK 和 root_passwd指定zk的连接地址和后台管理的账户密码

使用docker-compose启动容器，镜像已经上传到Docker官方仓库
