PipFlow

Background

Pipflow is built for developers who deploy their Python software using Docker and Cloud Native technologies. When building docker images our constraints are:

• The more slim the image, the better.
• The less image layers, the better.
• Don't reinvent the wheel by installing a new package manager in your Dockerfile. These tools tend to use lock files, which are fine in general, but in Docker they are redundant because we already have a way to pin dependencies: Docker image layers.

This leave us with one option: Continue to use plain old pip, but create some new workflows that improve the developer experience.

For example, Pipflow replaces this workflow:

$ pip3 install <new-package>
$ pip3 freeze | grep <new-package> >> requirements.txt
$ docker build ... # (A redudant install)

with this:

$ pipflow add <package>

Setup

Install pipflow on your HOST OS only (macOS, Windows, Linux etc). Do not add Pipflow to your requirements.txt.

pip3 install pipflow
