noonoo

Tool to clean up Elastic Container Repositories in AWS.

The name is lifted from "Noo-Noo", a character on the BBC children's television show Teletubbies. The Wikipedia description says it best: The Noo-noo is a conscientious vacuum cleaner who acts as both the Teletubbies' guardian and housekeeper. He hardly ever ventures outside the Tubbytronic Superdome, instead remaining indoors and constantly cleaning with his sucker-like nose. He communicates through a series of slurping and sucking noises.

Setup

$ pip install noonoo

Noonoo uses AWS boto, so it will pickup AWS credentials via AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables, or via ~/.aws. See boto3 configuration for details.

Usage

$ noonoo --help

Background

At Takumi we push app container images into ECR's as part of our CI process. These ECR's have the standard size limit of 1000 images, and when they fill up our CI pipeline breaks. Noonoo is a repackaged version of a janitor script I wrote for some internal deployment tools we're no longer using.
