【问题描述】：

我正在运行 docker-compose up -d 并收到以下错误消息：

Creating webserver ... 
Creating webserver ... error

ERROR: for webserver  Cannot start service webserver: error while mounting volume '/var/lib/docker/volumes/backend_dhparam/_data': failed to mount local volume: mount /home/root/SemanaOMnistack/backend/dhparam/:/var/lib/docker/volumes/backend_dhparam/_data, flags: 0x1000: no such file or directory

ERROR: for webserver  Cannot start service webserver: error while mounting volume '/var/lib/docker/volumes/backend_dhparam/_data': failed to mount local volume: mount /home/root/SemanaOMnistack/backend/dhparam/:/var/lib/docker/volumes/backend_dhparam/_data, flags: 0x1000: no such file or directory
ERROR: Encountered errors while bringing up the project.

我在docker-compose.yml 中的卷路径是：

volumes:
  certbot-etc:
  certbot-var:
  dhparam:
    driver: local
    driver_opts:
      type: none
      device: /home/root/SemanaOMnistack/backend/dhparam/
      o: bind

没关系，路径错误，我修复它创建一个新用户并更改docker-compose.yml 中的音量：

volumes:
  certbot-etc:
  certbot-var:
  dhparam:
    driver: local
    driver_opts:
      type: none
      device: /home/leo/dev-maps/backend/dhparam/
      o: bind

当我运行docker-compose up -d --build 时指定的卷路径编写相同的错误消息：

Creating webserver ... 
Creating webserver ... error

ERROR: for webserver  Cannot start service webserver: error while mounting volume '/var/lib/docker/volumes/backend_dhparam/_data': failed to mount local volume: mount /home/root/SemanaOMnistack/backend/dhparam/:/var/lib/docker/volumes/backend_dhparam/_data, flags: 0x1000: no such file or directory

ERROR: for webserver  Cannot start service webserver: error while mounting volume '/var/lib/docker/volumes/backend_dhparam/_data': failed to mount local volume: mount /home/root/SemanaOMnistack/backend/dhparam/:/var/lib/docker/volumes/backend_dhparam/_data, flags: 0x1000: no such file or directory
ERROR: Encountered errors while bringing up the project.

我尝试了docker system prune -a 之类的所有方法并清除了我的 Docker 的所有缓存，并且显示了相同的错误消息！

我只是解决了将卷的名称更改为例如dhparam2 所以...问题不是路径而是缓存。

有人知道怎么解决吗？

【问题讨论】：

请出示您完整的docker-compose.yml，至少您的webserver服务定义。

标签： docker docker-compose

【解决方案1】：

我有时会在 docker-compose 中安装卷时遇到类似的问题，这些问题一直对我有用：

docker-compose down -v --remove-orphans

docker-compose up -d -V --build --force-recreate

请使用--help 更详细地了解每个标志的作用。希望这对你有用！

这解决了我的问题。需要 -v 来更新路径
