Answer 1

It sounds like you're trying to start a container from a 14GB image.

A Docker container, when using the devicemapper storage driver, only has 10GB of space available by default. You appear to be using the devicemapper driver, so this is probably the source of your problem.

This article discusses in detail the process you need to use to increase the amount of space available for container filesystems.

Filesystem-based drivers (like the overlay driver) to not have this same limitation (but they may of course suffer from other limitations).

Docker运行，设备上没有剩余空间
