docker-shaball

This little script helps you bundle up a bunch of Docker images for distribution e.g. to S3.

Sample usage:

  $ docker-shaball nginx:1.9 ruby:2.2
  f5fe78d69d93b719109341295a024b62c84ebc28.tar.gz

The named images are exported from your local Docker daemon using docker save, and saved as a CHECKSUM.tar.gz archive. The archive file-name includes a checksum of a "manifest" formed using the named Docker images and the corresponding IDs. Specify the --manifest flag to see the manifest:

  $ docker-shaball --manifest nginx:1.9 ruby:2.2
  nginx:1.9 72d73c46937aaf8ca1efe566cac0564a05a0f1aeaef770658c8201726cfff50b
