Serverless ECR Cleaner

This project is deprecated

Try ECR lifecycle policies to clean up old images.

Setup

Requires Serverless to be installed (Project currently Serverless v0.5.x)

git clone https://github.com/trek10inc/ecr-cleaner

With admin credentials for your account in the cloned directory serverless project init

Otherwise, generate CF template and deploy resources manually with console serverless project init -c (Doesn't execute CF, just generates it)

Install Dependencies cd main && npm install

Setup environment variables... (Be sure to remove the comments!)

}

Deploy

sls dash deploy

Dry Run

To test and make sure things are working as you expect before deleting a whole bunch of images you can pass in a dry run options as part of the lambda event either via the console or when running locally.

# main/event.json
{
	"dryRun":true
}

// Local run command: sls function run main --stage dev
