可以编写lambda函数定期检查ECS集群是否有任何正在使用的ECR镜像，如果有，则更新这些镜像的过期时间，以避免它们在使用期间过期。以下是Python代码示例：

import boto3
import datetime

def update_ecr_image_expire_date(cluster_name, repository_name, image_tag, expire_days):
    client = boto3.client('ecr')

    # calculate new expire date
    new_expire_date = datetime.datetime.now() + datetime.timedelta(days=expire_days)

    # update image expire date
    client.batch_set_image_expiry(
        repositoryName=repository_name,
        imageIds=[
            {
                'imageTag': image_tag
            },
        ],
        lifecyclePolicyPreviewFilter={
            'tagStatus': 'ANY',
            'countType': 'sinceImagePushed',
            'countUnit': 'days',
            'countNumber': expire_days
        },
        expireAfter=new_expire_date
    )

def lambda_handler(event, context):
    # get ECR image detail
    client = boto3.client('ecr')
    result = client.describe_images(
        registryId=event['registry_id'],
        repositoryName=event['repository_name']
    )

    # check if any ECS cluster is still using the image
    for image in result['imageDetails']:
        image_tag = image['imageTags'][0]
        expire_date = image['imagePushedAt'] + datetime.timedelta(days=image['imageManifest']['imageExpirationTimeout'])

        for cluster_arn in image['imageManifest']['imageUses']:
            ecs = boto3.client('ecs')
            cluster_name = cluster_arn.split('/')[1]
            response = ecs.list_container_instances(
                cluster=cluster_name,
                status='ACTIVE'
            )
            if response['containerInstanceArns']:
                # ECS cluster is still using the image, update the image expire date
                update_ecr_image_expire_date(cluster_name, event['repository_name'], image_tag, (expire_date - datetime.datetime.now()).days)
