Dockerfile模板和Docker Compose模板

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：

version: "3.8"

services:
  mysql:
    image: mysql
    container_name: mysql
    ports:
      - "3306:3306"
    environment:
      TZ: Asia/Shanghai
      MYSQL_ROOT_PASSWORD: 123
    volumes:
      - "./mysql/conf:/etc/mysql/conf.d"
      - "./mysql/data:/var/lib/mysql"
      - "./mysql/init:/docker-entrypoint-initdb.d"
    networks:
      - hm-net
  hmall:
    build: 
      context: .
      dockerfile: Dockerfile
    container_name: hmall
    ports:
      - "8080:8080"
    networks:
      - hm-net
    depends_on:
      - mysql
  nginx:
    image: nginx
    container_name: nginx
    ports:
      - "18080:18080"
      - "18081:18081"
    volumes:
      - "./nginx/nginx.conf:/etc/nginx/nginx.conf"
      - "./nginx/html:/usr/share/nginx/html"
    depends_on:
      - hmall
    networks:
      - hm-net
networks:
  hm-net:
    name: hmall
