EMR Notebooks 的服务角色

每个 EMR Notebooks 都需要权限来访问其它Amazon资源和执行操作。附加到该服务角色的 IAM policy 为笔记本提供了与其它Amazon服务进行交互操作的权限。当您使用Amazon Web Services Management Console创建笔记本时，您指定一个Amazon服务角色。您可以使用默认角色 EMR_Notebooks_DefaultRole，也可以指定您创建的角色。如果之前尚未创建笔记本，则可以选择创建默认角色。

您的服务角色应该使用下面的信任策略。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "elasticmapreduce.amazonaws.com"
            },
            "Action": "sts:AssumeRole",
            "Condition": {
                "StringEquals": {
                    "aws:SourceAccount": "<account-id>"
                },
                "ArnLike": {
                    "aws:SourceArn": "arn:aws:elasticmapreduce:<region>:<account-id>:*"
                }
            }
        }
    ]
}

版本 1 的内容 AmazonElasticMapReduceEditorsRole 如下所示。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ec2:AuthorizeSecurityGroupEgress",
                "ec2:AuthorizeSecurityGroupIngress",
                "ec2:CreateSecurityGroup",
                "ec2:DescribeSecurityGroups",
                "ec2:RevokeSecurityGroupEgress",
                "ec2:CreateNetworkInterface",
                "ec2:CreateNetworkInterfacePermission",
                "ec2:DeleteNetworkInterface",
                "ec2:DeleteNetworkInterfacePermission",
                "ec2:DescribeNetworkInterfaces",
                "ec2:ModifyNetworkInterfaceAttribute",
                "ec2:DescribeTags",
                "ec2:DescribeInstances",
                "ec2:DescribeSubnets",
                "ec2:DescribeVpcs",
                "elasticmapreduce:ListInstances",
                "elasticmapreduce:DescribeCluster",
                "elasticmapreduce:ListSteps"
            ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": "ec2:CreateTags",
            "Resource": "arn:aws:ec2:*:*:network-interface/*",
            "Condition": {
                "ForAllValues:StringEquals": {
                    "aws:TagKeys": [
                        "aws:elasticmapreduce:editor-id",
                        "aws:elasticmapreduce:job-flow-id"
                    ]
                }
            }
        }
    ]
}

下面是 S3FullAccessPolicy 的内容。S3FullAccessPolicy 允许 EMR Notebooks 的服务角色对 Amazon Web Services 账户 中的对象执行所有 Amazon S3 操作。当您为 EMR Notebooks 创建自定义服务角色时，必须向服务角色授予 Amazon S3 权限。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "s3:*",
            "Resource": "*"
        }
    ]
}

您可以将服务角色的读写权限范围缩小到要保存笔记本文件的 Amazon S3 位置。使用以下最小 Amazon S3 权限集。

"s3:PutObject",
"s3:GetObject",
"s3:GetEncryptionConfiguration",
"s3:ListBucket",
"s3:DeleteObject"              

如果您的 Amazon S3 存储桶已加密，您必须为 Amazon Key Management Service 包含以下权限。

"kms:Decrypt",
"kms:GenerateDataKey",
"kms:ReEncryptFrom",
"kms:ReEncryptTo",
"kms:DescribeKey"

当您将 Git 存储库链接到笔记本并需要为存储库创建密钥时，您必须在附加到 Amazon EMR Notebooks 的服务角色的 IAM policy 中添加 secretsmanager:GetSecretValue 权限。下面演示了一个示例策略：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "secretsmanager:GetSecretValue",
            "Resource": "*"
        }
    ]
}
