🛁 A golang implementation for removing old images from ECR repositories

ecr-cleanse

The documented limit to the number of images in an ECR repository is 1000 (Now 10K as of Jul 19 2019). This is a golang implementation for removing unused images from your ECR repositories.

This script will inspect all container services/tasks, across all ECS clusters, removing images that are not in-use (in batches of 100).

Usage

go run main.go

Flags

• -aws-region: Pass your AWS region.
• -dry-run: Execute the script without purging any images.

go run main.go -aws-region us-west-2 -dry-run
