如何创建一份springboot的docker镜像

FROM centos:7

ENV JAVA_HOME /usr/java/jdk1.7.0_55

ENV MAC_PUBLISH_PATH /home/app

ENV LOG_PATH /var/log

ENV PATH $JAVA_HOME/bin:$PATH

ENV TIME_ZONE Asia/Shanghai

COPY jdk-7u55-linux-x64.rpm /opt/

RUN mkdir -p $MAC_PUBLISH_PATH && mkdir -p "$LOG_PATH" && rpm -ih /opt/jdk-7u55-linux-x64.rpm \

&& rm -rf /opt/jdk-7u55-linux-x64.rpm

COPY spring-boot-xxx-ap一p-0.0.1-SNAPSHOT.jar $MAC_PUBLISH_PATH

COPY config $MAC_PUBLISH_PATH/config

WORKDIR $MAC_PUBLISH_PATH

RUN set -xe \

&& chown -R 1000:1000 "$MAC_PUBLISH_PATH" \ && chown -R 1000:1000 "$LOG_PATH" \ && echo "${TIME_ZONE}" > /etc/timezone \ && ln -sf /usr/share/zoneinfo/${TIME_ZONE} /etc/localtime

EXPOSE 8090

VOLUME $LOG_PATH

VOLUME /$MAC_PUBLISH_PATH/config

ENV LANG en_US.UTF-8

CMD ["java","-jar","/home/app/spring-boot-xxx-app-0.0.1-SNAPSHOT.jar"]

以上是Dockerfile一个很好的模板，所有资源文件必须跟Dockerfile在同一文件夹。最后输入命令docker build -t 镜像标签 路径
