jar包打包成镜像文件

jar包打包成镜像文件

目录结构

build.sh

#!/bin/bash
# set -x
echo "---------------------------------------------"
echo "1、打包的文件夹与镜像名保持一致"
echo "2、打包的文件夹中必须包含Dockerfile与jar包"
echo "3、Dockerfile中定义的jar包名称与提供的jar包名一致"
echo "---------------------------------------------"

        exit 1

function read_dir(){
    for file in `ls $1`
    do
    cp -r $1"/"$file $image_name
    shares[${#shares[@]}]=$file
    done
}

Dockerfile

FROM openjdk:8
WORKDIR /app/etc/
LABEL USER=HULAN

#名称为你打包的jar
ENV JARNAME=datalook-wechat-ui-2.1.4.RELEASE.jar

COPY ${JARNAME} /app/lib/${JARNAME}
COPY startup.sh /app/bin/startup.sh

RUN chmod +x /app/bin/startup.sh
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

ENTRYPOINT ["sh","/app/bin/startup.sh"]

startup.sh

set -x
#如果未配置xmx和xms则使用感知功能
if [ ! -z "${XMX}" ] && [ ! -z "${XMS}" ]; then
    JAVA_OPT="${JAVA_OPT} -Xmx${XMX} -Xms${XMS}"
fi

JAVA_OPT="${JAVA_OPT} -XX:+HeapDumpOnOutOfMemoryError"
JAVA_OPT="${JAVA_OPT} -XX:HeapDumpPath=/app/etc"
JAVA_OPT="${JAVA_OPT} -XX:+ExitOnOutOfMemoryError"
JAVA_OPT="${JAVA_OPT} -Duser.timezone=GMT+08"
JAVA_OPT="${JAVA_OPT} -Dspring.config.location=/app/etc/"
JAVA_OPT="${JAVA_OPT} /app/lib/${JARNAME}"

java -jar ${JAVA_OPT}

打包的镜像包会复制到本地文件夹里面
