ecr_clean.py

import boto3

client = boto3.client('ecr')

response = client.describe_repositories(maxResults=50)
next_token = response.get('nextToken')

while len(response['repositories']) > 0:
    for r in response['repositories']:
        print(f"Deleting {r['repositoryName']}")
        response = client.delete_repository(
            repositoryName=r['repositoryName'],
            force=True
        )

    response = client.describe_repositories(maxResults=50, nextToken=next_token)
    next_token = response.get('nextToken')
