在构建容器时，我收到：
Error processing tar file(exit status 1): write xxx: no space left on device.
在运行此构建之前，我基于this发出了命令docker system prune

我什至重新安装了Docker并修改了启动脚本/usr/lib/systemd/system/docker.service，并将--storage-opt参数添加为：
ExecStart=/usr/bin/dockerd --storage-opt dm.basesize=50G -H fd:// --containerd=/
，然后重新启动Docker。我是Azure的新手，能够以12.5GiB的价格将此Dockerfile构建在AWS上。
如何使该图像正确构建？
