使用qemu-img创build磁盘映像会导致docker-compose版本由于空间不足而失败

我刚做了一个IDS的Linux发行版Security Onion，工作在Docker KVM容器中。 （ Repository ）然而，磁盘镜像会造成docker-composer build崩溃

我的电脑有300GB的免费。 我为KVM容器创build一个磁盘映像：

qemu-img create ./image/disk.img 20G

当我再次构buildDocker镜像时，Docker组合抛出

OSError: [Errno 28] No space left on device 。

我必须删除磁盘映像或更新$TMPDIR目录到/home/tmp （它有足够的空间），使docker-compose build重新生成工作。 我注意到由docker-composer在/home/tmp创build的tmp文件可以增长到20GB。 计算机在构build过程中也处于冻结状态。

为什么磁盘映像导致构build过程由于空间问题而失败？ 磁盘映像只需要20GB。

错误：
