Question

我是码头工人的新手。我已经尝试了不到两周的时间。我们有一项服务，我们希望迁移到容器中。该服务使用了大约50G的数据，因此我们希望图像非常大。我们为它编写了一个Dockerfile。当我们运行构建时，它会失败，并带有ff：

ApplyLayer exit status 1 stdout: stderr: write /mnt/spine_features/spine_features_subset.lmdb/data.mdb: input/output error

当我们检查docker ps -a的容器时，我们可以看到列出的构建容器状态为：

Exited (1) About a minute ago

当我们尝试提交容器时，我们得到了同样的错误：

Error response from daemon: ApplyLayer exit status 1 stdout: stderr: write /mnt/spine_features/spine_features_subset.lmdb/data.mdb: input/output error

我们也可以停靠检查容器。当我们排除下载最大的文件时，我们能够完成构建服务图像。是否有某种配置我们可以改变成功，同时还包括更大的文件？

Answer 1

正如Haoming Zhang所建议的那样，将主机目录安装到容器中是一种可接受的解决方案。我们还在探索使用FUSE在运行时将数据加载到容器中的可能性，而不是在构建期间将其烘焙到映像中，或者让主机在运行容器时将其传递到容器中。
