docker-mounter

Utility to mount Docker images locally without requiring container creation. This is useful for analysing contents of Docker images from within the host operating system without incurring the overhead of container creation.

This tool relies on some potentially unstable docker implementation details, and may break in future Docker versions!

Compatibility

Due to use of overlay2, tool is only compatible with Linux 3.19+.

It has currently only been tested with Docker version 27.3.1, build ce12230.
