Failed to start devcontainer - no space left on device
When this happen, open “Docker Desktop” GUI console and clean up useless Images or Containers. But this way wil run into an end, like this time.
First of all, df -H to make sure you have enough free space
已经都删干净了啊， Docker 系统中有 3 个镜像，3 个容器，8 个本地数据卷和 423 个构建缓存文件。

dangerous system prune –volumes
Note it will delete all stopped containers, and since there is no more containers, it will continue to delete all volumes (because they are not used by at least one container). It will also delete all build cache of course, so you end up have to rebuild all your containers, and lost all data in devconainers which not added by yourself, excpet you the repo you have pushed up.

This is much better way when you don’t have much containers or volumes to clean up.
