history
Project history and usage
docker-squash is a Python CLI for squashing Docker image layers. It grew out of a practical image-size problem: Dockerfile instructions create layers, temporary build artifacts can remain in earlier layers, and pushing, saving, or loading those images can cost unnecessary time and storage.
Project history
The README describes docker-squash as a tool that can squash the last n layers of an image or squash from a selected layer to the end, then load the result back into the Docker daemon or store it as a tar archive. It explicitly frames squashing as a way to organize images into more logical layers and avoid carrying temporary files.
Adoption history
The project was packaged for installation from source, PyPI, and Homebrew. Its relevance is strongest in the legacy Docker builder era, before BuildKit and multi-stage builds reduced the need for post-processing images to remove build-time artifacts.
How it is used
A typical command selects an image, optionally sets --from-layer or a number of layers, tags the new image with --tag, writes an archive with --output-path, or controls whether the result is loaded back into Docker. The README examples compare docker history before and after squashing to show layer changes.
Why package nerds care
docker-squash is notable because it packages image-layer surgery as a normal CLI command. It is a useful historical artifact for understanding how Docker users handled layer bloat before modern Dockerfile patterns and BuildKit made the problem less central.
Timeline
- Docker 1.9 era: The README documents Docker 1.9 or newer support.
- Python 3 era: The README documents Python 3.6 and newer support.
- BuildKit era: Docker documents the legacy Linux image builder as deprecated, making squashing tools more historical and niche.
