Docker容器未启动，因为Rabbit磁盘空间不足。

Question

RabbitMQ似乎占用了太多的磁盘空间，无法启动。我该如何在我的Mac上删除它？我找不到它。我已经尝试删除所有镜像和容器，并从头开始重建，但希望能解决问题。

$docker logs rabbitmq

我可以在docker-compose.yml中为Rabbit定义一个物理卷吗？

- Tino

---

你只有50MB的空间。你可以在rabbit conf中更改。 - Antoniossss

谢谢。对于生产环境是的，但是在本地开发时运行它时，我可以传递一个命令给Compose，在每次启动时清理它吗？ - Tino

Answer 1

这两个命令完成了工作：

 docker rmi $(docker images -q) //removes all images
 docker volume rm $(docker volume ls -f dangling=true -q) // removes all volumes

- Tino

---

未来的读者：只需移除悬挂的卷（第二个命令），就可以解决这个问题。不需要删除所有的镜像。 - mga226

@mga226 谢谢，来自未来。 - Ben Lamm

Answer 2

你可以运行以下命令来清除悬挂的卷：

`

`

docker system prune -a
