README

diff-exporter

The diff-exporter extracts (exports) the diff layer given a running container ID and a bundle path (that contains the config.json). The layer is saved to the location provided by the -outputFile parameter. The output layer is of tar.gz mediatype and the filename is the sha256 of its contents.

Building

Make sure GOPATH is set. Then run:

go build

It generates a diff-exporter.exe in the current directory.

Usage

diff-exporter.exe <-outputFile outputFile> <-containerId containerId> <-bundlePath bundlePath>
