记录一下Dockerfile模板和Docker Compose模板，

基础的系统加JDK环境来构建一个Java应用，其Dockerfile内容如下：

# 基础镜像
FROM openjdk:11.0-jre-buster
# 设定时区
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# 拷贝jar包
COPY docker-demo.jar /app.jar
# 入口
ENTRYPOINT ["java", "-jar", "/app.jar"]

用docker-compose.yml 模板文件实现多个相互关联的Docker容器的快速部署：
