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.
Make sure GOPATH is set. Then run:
go build
It generates a diff-exporter.exe in the current directory.
diff-exporter.exe <-outputFile outputFile> <-containerId containerId> <-bundlePath bundlePath>
To run the entire suite of tests, do ginkgo -r .
The tests require the following env variables to be set:
-
GROOT_BINARY -
GROOT_IMAGE_STORE -
WINC_BINARY -
WINC_TEST_ROOTFS
