需要为IAM用户或角色提供ECR权限。可以通过为IAM策略添加以下内容来实现权限控制：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ecr:GetAuthorizationToken",
                "ecr:BatchCheckLayerAvailability",
                "ecr:GetDownloadUrlForLayer",
                "ecr:GetRepositoryPolicy",
                "ecr:DescribeRepositories",
                "ecr:ListImages",
                "ecr:DescribeImages",
                "ecr:BatchGetImage"
            ],
            "Resource": "*"
        }
    ]
}

此外，还需确保IAM用户或角色的访问密钥和密码正确。
