通用dockerfile文件-优快云博客

先写项目的启动脚本，命名为`run.sh`

#!/bin/sh

if [ -z $JAVA_OPTS ];then
    JAVA_OPTS="-Xms256m -Xmx512m"
fi

if [ -z $JAR_PATH ];then
    JAR_PATH="/opt/server"
fi

if [ -z $EXAM_ENV ];then
    EXAM_ENV="prod"
fi

if [ x$LOG != "xfalse" ];then
    mkdir -p logs
    LOGGING_OPT="--logging.path=./logs"
fi

echo $JAVA_OPTS -Dlogging.path=./logs -DSpring.profiles.active=$EXAM_ENV -jar ${JAR_PATH}/*.jar

java $JAVA_OPTS -Dlogging.path=./logs -DSpring.profiles.active=$EXAM_ENV -jar ${JAR_PATH}/*.jar

`dockerfile`文件打包镜像

FROM openjdk:8

RUN mkdir -p /opt/server/

COPY target/${'项目名称'}-SNAPSHOT.jar /opt/server

COPY run.sh /opt/server/

COPY src/main/resources/static /server

EXPOSE 8888

WORKDIR /opt/server

ENTRYPOINT ["sh", "/opt/server/run.sh"]
