# 可通过以下两种方式传入配置
# 1. 环境变量（正式环境推荐该方式）
#   支持通过下列环境变量来传递配置信息。若同时设置，则按下面顺序取第一个非空的环境变量作为配置
# 示例：docker run --env DJC_HELPER_CONFIG_TOML="$DJC_HELPER_CONFIG_TOML" fzls/djc_helper:latest
# toml配置
ENV DJC_HELPER_CONFIG_TOML=""
# toml配置编码为base64
ENV DJC_HELPER_CONFIG_BASE64=""
# toml配置先通过lzma压缩，然后编码为base64
ENV DJC_HELPER_CONFIG_LZMA_COMPRESSED_BASE64=""
# toml配置解析后再序列化为单行的JSON配置
ENV DJC_HELPER_CONFIG_SINGLE_LINE_JSON=""

# 2. 映射本地配置文件到容器中（调试时可以使用这个）
# docker run --mount type=bind,source=local/absolute/path/to/config.toml,target=/djc_helper/config.toml fzls/djc_helper:latest

# 复制源码（最常改动的内容放到最后，确保修改代码后仅这部分内容会变动，其他层不变）
COPY . .
