### 一、 使用Docker镜像发布自己的jar项目 ###

#### 1、首先获取基础镜像alpine ####

[Docker镜像官方仓库][Docker]

docker pull alpine

> 拉取基础镜像后 构建一个含有jdk的基础镜像  
> 我们可以使用oracleJdk 也可以使用open JDK【注意使用openJDK构建的基础镜像在启动java项目的时候会出现下面的报错】

#### 2、构建含有jdk的基础镜像 ####

FROM 官方的:alpine
    
    ## Container labels
    LABEL maintainer="yangzailehehe <yangzailehehe -2@yang.com>"
    LABEL version="base"
    LABEL description="基于alpine + jdk-8u181-linux-x64【选用你用的jdk】打出的基础镜像"
    
    
    
    #需要添加的包，这些包放在dockerfile的同级，/usr/local，制定包放的位置
    ADD jdk-8u181-linux-x64.tar.gz /usr/local
    #设置JVM环境变量
    ENV JAVA_OPTS="-server -Xms1024m -Xmx2048m -Dfile.encoding=utf-8 -Dsun.jnu.encoding=utf-8"
    #设置jdk环境变量
    ENV JAVA_HOME /usr/local/jdk1.8.0_181
    ENV CLASSPATH $JAVA_HOME/lib
    ENV PATH $PATH:$JAVA_HOME/bin
    
    #暴露端口
    EXPOSE 80/tcp

> `docker build /xy/ --tag mlogtools/mr_log`  
> 打标签 然后如果有需要就启动容器进去修改一些东西然后commit 重新提交镜像，没有需要就直接推送到自己的harbor仓库就可以。

#### 3、基于已有的jdk镜像部署自己的项目 ####

*  Dockerfile如下：

FROM registry.aaa.com:5000/yang/java:alpine
    ## Container labels
    LABEL maintainer="yang-2 <yang-2@yang.com>"
    LABEL version="base"
    LABEL description="基于java打出的日志分析工具镜像"
    
    VOLUME ["/usr/local"]
    
    #需要添加的包，这些包放在dockerfile的同级，/usr/local，制定包放的位置
    COPY analyze.jar /usr/local
    COPY function.xlsx /usr/local
    COPY host.access.log /usr/local
    COPY analyze.sh /
    RUN chmod 777 /analyze.sh \
      && apk add --update font-adobe-100dpi ttf-dejavu fontconfig
    
    #暴露端口
    EXPOSE 80/tcp
    
    ENTRYPOINT ["nohup","java","-jar","/usr/local/analyze.jar","--analyze.result-dir=/usr/local/analyze_result.xlsx","--analyze.nginx-log-dir=/usr/local/host.access.log","--analyze.interface-excel-dir=/usr/local/m-function.xlsx","--server.port=18080",">","./analyze.nohup","2>&1","&"]

> docker build /xy/ --tag mlogtools/mr\_log
