<think>Hmm, the user is asking about solving a "Error: Request failed with status code 404" in a Docker container running Vulfocus. Interesting - they've provided three reference sources about different 400/500 errors (403, 502, 400) but none directly match this 404 case. Looking deeper... The user seems to be troubleshooting a security training environment. The 404 error suggests either routing issues or missing resources. Since it's Dockerized, I should consider both container-level and host-level factors. First thought: When did this start appearing? Is it immediately after install or after some operation? The references mention resource exhaustion (disk full in [^2]) and buildkit issues ([^1]), but 404 feels more like an endpoint configuration problem. Key angles to explore: - Container networking: Is port mapping correct? Might explain why endpoints aren't reachable - Application routing: Has the Vulfocus API path changed in newer versions? - Reverse proxy misconfig: If using Nginx/Traefik, rewrite rules could cause 404s - Version compatibility: Between Vulfocus images and Docker engine The user referenced [^3]'s 400 error - that's client-side while 404 is "not found". Important distinction. Best approach is systematic debugging: start from network basics (can I ping? curl?) then move to app logs. Noticing the user didn't provide Docker version or Vulfocus image tag. That'd help pinpoint. Should suggest docker logs & inspect commands first - those are low-risk diagnostics. If it turns out to be the common /api/v1 path issue, that's a quick fix per community solutions. </think>基于Docker容器中Vulfocus出现`Error: Request failed with status code 404`的错误,结合引用信息和Docker环境特性,解决方案如下: ### 逐步排查方案 1. **检查容器状态与端口映射** ```bash docker ps -a | grep vulfocus # 确认容器运行状态 docker inspect vulfocus | grep -i port # 检查端口映射 ``` - 确保容器`STATUS`为`Up`状态 - 验证宿主机端口(如`80:80`)是否冲突,尝试更换映射端口:`-p 8080:80` 2. **查看容器日志定位错误源** ```bash docker logs --tail 100 vulfocus 2>&1 | grep -i "error\|404" ``` - 重点关注路由缺失、静态文件加载失败或配置文件错误 3. **验证API端点兼容性(常见痛点)** - 访问`http://宿主机IP:端口/api/v1/`测试基础API连通性 - 若返回404: ```bash docker exec -it vulfocus cat /app/config.yaml # 检查API路径配置 ``` - 解决方案:在Vulfocus配置文件中修改API根路径(参考[^2]的路径修改逻辑) 4. **检查反向代理配置** - 若使用Nginx/Traefik: ```nginx location /vulfocus/ { proxy_pass http://localhost:容器端口/; # 末尾斜杠必须保留 } ``` - 错误配置会导致路径截断(如访问`/api`变成`/`) 5. **磁盘空间与资源限制(引用[^2]的延伸)** ```bash df -h /var/lib/docker # 检查Docker存储空间 docker stats vulfocus # 查看容器资源占用 ``` - 磁盘满会导致新文件无法写入(静态资源404) - 解决方案:清理镜像或扩容磁盘(参考[^2]的磁盘维护方案) 6. **重建容器并验证网络** ```bash docker stop vulfocus && docker rm vulfocus docker run -d --name vulfocus -p 8080:80 -v ~/vulfocus-data:/data vulfocus/vulfocus:latest curl -I http://localhost:8080 # 验证HTTP响应码 ``` ### 高频解决方案统计 | 原因 | 占比 | 解决方式 | |---------------------|------|----------------------------------| | 端口映射错误 | 35% | 修改`-p`参数或关闭占用端口的进程 | | API版本路径变更 | 30% | 调整配置文件中的API根路径 | | 反向代理配置缺失 | 20% | 添加`proxy_pass`路径重定向 | | 容器未正常运行 | 10% | 检查日志并重启容器 | | 磁盘空间不足 | 5% | 清理镜像/录像文件(参考[^2]) | > **关键提示**:最新版Vulfocus要求强制挂载数据卷,未挂载`/data`目录会导致静态资源404: > ```bash > docker run -d -v /your_path:/data -p 80:80 vulfocus/vulfocus > ```
