A small container engine to download and run docker images locally

Portable Container Engine

This project want to create a small executable that makes it possible to download and explore the file system of docker images. For this it has two main modes of operation: run and download. Run downloads an image, extracts the fs and runs it. The download command just downloads the full image and saves it as a tar file.

How to Use

go run cmd/pce/main.go <run|download> <image> <command>

Not yet supported:

• not all namespaces
• cGroups
• does not run the docker intened command

Special Thanks
