Mac 上开发 Ragflow

说明

在「Mac 上编译 Ragflow」的文章中只是简单的说到可以通过 Remote Development 来进入容器，可以通过修改Dockerfile的方式，增加映射卷的方式来开发。为什么要映射卷呢？这样可以保持 ragflow 原有的目录结构，同时保持 git 的代码管理，文件在卷中也不用担心因容器销毁等导致修改代码丢失的情况。

我今天完整的走通了开发的过程，重新整理开发部分的文档。为了保持完整，保留了 Remote Development 的部分说明。注意，前提是已经在 Mac 上编译完 ragflow 的 Dockerfile，并且可以正常运行。

开发

Remote Development

VS Code 安装 Remote Development 插件。它包含多个插件，其中 Dev Containters 可以连接到 Docker 容器作为开发环境，这样的好处是开发环境与部署环境一致。

当安装好 Remote Development，就可以通过 Remote Explorer 查看已经安装的容器，并通过点击对应容器的箭头（注意下图红色框的部分）。

进入到容器内部，选对应的目录，就可以打开 /ragflow，这样就能看到实际的代码了。

修改Dockerfile

主要是屏蔽编译过程和 probuction 步骤，增加 /raflow 卷的映射。

重新编译镜像

docker build --build-arg LIGHTEN=1 --build-arg NEED_MIRROR=1 -f Dockerfile -t infiniflow/ragflow:nightly-slim .

修改docker-compose-macos.yml

这里设置本地的 ragflow 为镜像的/ragflow卷的，映射目录。这的好处就是还可以保留 git 的代码管理。

include:
  - ./docker-compose-base.yml

services:
  ragflow:
    depends_on:
      mysql:
        condition: service_healthy
    build:
      context: ../
      dockerfile: Dockerfile
    container_name: ragflow-server
    ports:
      - ${SVR_HTTP_PORT}:9380
      - 80:80
      - 443:443
    volumes:
      - ./ragflow-logs:/ragflow/logs
      - ./nginx/ragflow.conf:/etc/nginx/conf.d/ragflow.conf
      - ./nginx/proxy.conf:/etc/nginx/proxy.conf
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ../:/ragflow
    env_file: .env
    environment:
      - TZ=${TIMEZONE}
      - HF_ENDPOINT=${HF_ENDPOINT}
      - MACOS=${MACOS:-1}
      - LIGHTEN=${LIGHTEN:-1}
    networks:
      - ragflow
    restart: on-failure
    # https://docs.docker.com/engine/daemon/prometheus/#create-a-prometheus-configuration
    # If you're using Docker Desktop, the --add-host flag is optional. This flag makes sure that the host's internal IP gets exposed to the Prometheus container.
    extra_hosts:
      - "host.docker.internal:host-gateway"

因为增加了 ragflow 的卷映射，这里注意拷贝 docker/service_conf.yaml.template 到 ragflow/conf 目录下，docker/entrypoint.sh docker/entrypoint-parser.sh 拷贝到 raflow 目录下，避免程序无法启动。

cd docker
$ docker compose -f docker-compose-macos.yml up -d

修改entrypoint.sh

增加 --debug 支持调试信息。

#!/bin/bash

# replace env variables in the service_conf.yaml file
rm -rf /ragflow/conf/service_conf.yaml
while IFS= read -r line || [[ -n "$line" ]]; do
    # Use eval to interpret the variable with default values
    eval "echo \"$line\"" >> /ragflow/conf/service_conf.yaml
done < /ragflow/conf/service_conf.yaml.template

/usr/sbin/nginx

export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

PY=python3
if [[ -z "$WS" || $WS -lt 1 ]]; then
  WS=1
fi

function task_exe(){
    JEMALLOC_PATH=$(pkg-config --variable=libdir jemalloc)/libjemalloc.so
    while [ 1 -eq 1 ];do
      LD_PRELOAD=$JEMALLOC_PATH $PY rag/svr/task_executor.py $1;
    done
}

for ((i=0;i<WS;i++))
do
  task_exe  $i &
done

while [ 1 -eq 1 ];do
    $PY api/ragflow_server.py --debug
done

wait;

编译

正常情况下，这个时候服务是无法访问的，但容器已经启动，可以通过 dev containers 来访问容器。进入容器后编译前端和重新安装 ragflow 的 python 依赖。

前端

cd web
npm install
npm run build

后端

重新获取依赖

uv sync --python 3.10 --frozen;

验证

目录结构一致

外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传

修改下代码，比如api/apps/user_app.py。

我们可以看到修改的代码已经被执行。

小结

编程很多时候的问题是部署开发环境的问题，现在有了 docker 已经可以开发部署简单多了。但因为众所周知的原因，你还需要掌握科学上网的魔法。

这次部署 ragflow 环境下来，发现硬盘太小是个问题，模型或者镜像都要确定哪些没用了及时删除。
