# 校园新闻管理系统 - MySQL数据库镜像
# 基于reInit.sh的数据库初始化方案
FROM mysql:8.0

# 设置环境变量
ENV LANG=C.UTF-8 \

# 注意：MySQL配置有两种方式
# 1. 通过docker-compose.yml的command参数（基础配置）
# 2. 通过挂载my.cnf文件（高级配置，可选）
#    docker-compose.yml中可以取消注释: ./mysql/my.cnf:/etc/mysql/conf.d/my.cnf

# 创建SQL目录
RUN mkdir -p /docker-entrypoint-initdb.d /opt/sql

# 复制所有SQL文件（保持目录结构）
COPY schoolNewsServ/.bin/mysql/sql/ /opt/sql/

# 复制并调整reInit.sh为Docker环境，设置执行权限
COPY schoolNewsServ/.bin/mysql/sql/reInit.sh /opt/sql/
