1.0.0rc3

• Project was renamed from docker-scripts to docker-squash
• The layers subcommand was removed. This tool purely focuses on the squashing Docker images.
• Better error handling when executing the tool from CLI

1.0.0rc2

Enhancements

• Performance improvements. As part of #63 we investigated and fixed some performance issues. This makes squashing faster even by 40%. It depends of course on the image, but you can expect pretty big performance improvement in any case.

1.0.0rc1

Enhancements

• Add support for Docker 1.10 or newer which introduces new image format
• The --from-layer argument can take now numeric value which specifies how many layers should be squashed.
• Temporary directories are now removed in case of failure, see #44.
• Added --development, -d switch to enable development mode. Currently this enables full stacktraces and does not remove the temporary directories after failure.

Known issues

• In case you want to squash an image containing missing layers (see docker history IMAGE_ID to confirm) most probably you'll need to specify numeric value to the --from-layer argument which says how many layer you want to squash. It's impossible to reference a missing layer in other way because these layers do not have populated IDs.
• The layers sub-command doesn't work (yet)

0.4.4

• When you squash you can now create both - a tarred image and load it into Docker. Available only when running from an API, set the load_image to True and specify output_path too.
• Other small improvements when using the squash tool from API

0.4.3

• Uses AutoVersionClient to not fail when there is a mismatch between version of docker-py and the server
• Does not fail with stacktrace when no image is specified
• Version information is now printed on execution

0.4.2

• Make sure we do not include ./ as the prefix for files in the squashed tar, thanks @TomasTomecek!
• Squashed layers has now a proper VERSION file
• Fixed metadata size parameter

0.4.1

• Work on correct image JSON metadata (#28)

0.4.0

• Reworked the squashing algorithm
• Make loading image optional, use --output-path to specify a path where the image should be stored as TAR file instead loading to Docker daemon
• First unit tests added
• First integration tests added
• Docker timeout bumped to 10 minutes, now it's configurable using DOCKER_TIMEOUT environment variable
• Fixed issue where on AUFS the marker files that were added at the end failed to load the image into Dameon (#22)

0.3.6

• Make sure it can work with older six package
• Add --version switch

0.3.3

• Support for Python 3
• Fixed #13 where non-string PAX headers could fail squashing
