docker-optimizer 1.2.1
A small program to optimize Dockerfiles
License: BSD

``docker-optimizer`` allows collapsing multiple ``RUN`` layers into a
single one. This way, you can use the docker caching for development,
yet get fewer layers for the final container.

Installation
============

.. code:: sh

    pip install docker-optimizer

Usage
=====

Input ``Dockerfile.dev``:

.. code:: docker

    FROM python:3.8-slim-buster
