# 為 Managed Service for Apache Flink Studio 筆記本建立自訂 IAM 政策
<a name="how-zeppelin-appendix-iam"></a>

您通常會使用受管 IAM 政策來允許應用程式存取相依資源。如果需要更好地控制應用程式的許可，可以使用自訂 IAM 政策。本節包含自訂 IAM 政策的範例。

**注意**  
在下列政策範例中，使用應用程式的值取代預留位置文字。

**Topics**
+ [AWS Glue](#how-zeppelin-iam-glue)
+ [CloudWatch Logs](#how-zeppelin-iam-cw)
+ [Kinesis 串流](#how-zeppelin-iam-streams)
+ [Amazon MSK 叢集](#how-zeppelin-iam-msk)

## AWS Glue
<a name="how-zeppelin-iam-glue"></a>

下列範例政策會授予存取 AWS Glue 資料庫的許可。

            "Action": "glue:GetDatabases",
            "Resource": "*"
        }
    ]
}
```

## CloudWatch Logs
<a name="how-zeppelin-iam-cw"></a>

下列範例授與存取 CloudWatch 的許可。

```
{
      "Sid": "ListCloudwatchLogGroups",
      "Effect": "Allow",
      "Action": [
        "logs:DescribeLogGroups"
      ],
      "Resource": [
        "arn:aws:logs:<region>:<accountId>:log-group:*"
      ]
    },
    {
      "Sid": "ListCloudwatchLogStreams",
      "Effect": "Allow",
      "Action": [
        "logs:DescribeLogStreams"
      ],
      "Resource": [
        "<logGroupArn>:log-stream:*"
      ]
    },
    {
      "Sid": "PutCloudwatchLogs",
      "Effect": "Allow",
      "Action": [
        "logs:PutLogEvents"
      ],
      "Resource": [
        "<logStreamArn>"
      ]
    }
```

**注意**  
如果使用主控台建立應用程式，則主控台會為應用程式角色新增必要的政策，以存取 CloudWatch Logs。

## Kinesis 串流
<a name="how-zeppelin-iam-streams"></a>

應用程式可以將 Kinesis 串流用於來源或目的地。應用程式需要讀取許可才能從來源串流讀取，需要寫入許可才能寫入目的地串流。

下列政策授與從用作來源的 Kinesis 串流讀取的許可：

{
    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Sid": "KinesisShardDiscovery",
            "Effect": "Allow",
            "Action": "kinesis:ListShards",
            "Resource": "*"
        },
        {
            "Sid": "KinesisShardConsumption",
            "Effect": "Allow",
            "Action": [
                "kinesis:GetShardIterator",
                "kinesis:GetRecords",
                "kinesis:DescribeStream",
                "kinesis:DescribeStreamSummary",
                "kinesis:RegisterStreamConsumer",
                "kinesis:DeregisterStreamConsumer"
            ],
            "Resource": "arn:aws:kinesis:us-east-1:123456789012:stream/<stream-name>"
        },
        {
            "Sid": "KinesisEfoConsumer",
            "Effect": "Allow",
            "Action": [
                "kinesis:DescribeStreamConsumer",
                "kinesis:SubscribeToShard"
            ],
            "Resource": "arn:aws:kinesis:us-east-1:123456789012:stream/<stream-name>/consumer/*"
        }
    ]
}
```

下列政策授與向用作目的地的 Kinesis 串流寫入的許可：

#### [ JSON ]

****  

```
{
    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Sid": "KinesisStreamSink",
            "Effect": "Allow",
            "Action": [
                "kinesis:PutRecord",
                "kinesis:PutRecords",
                "kinesis:DescribeStreamSummary",
                "kinesis:DescribeStream"
            ],
            "Resource": "arn:aws:kinesis:us-east-1:123456789012:stream/<stream-name>"
        }
    ]
}
```

如果應用程式存取加密的 Kinesis 串流，則必須授與額外的許可，以存取該串流及其加密金鑰。

下列政策授與存取加密來源的串流和及其加密金鑰的許可：

```
{
      "Sid": "ReadEncryptedKinesisStreamSource",
      "Effect": "Allow",
      "Action": [
        "kms:Decrypt"
      ],
      "Resource": [
        "<inputStreamKeyArn>"
      ]
    }
    ,
```

下列政策授與存取加密目的地的串流和及其加密金鑰的許可：

```
{
      "Sid": "WriteEncryptedKinesisStreamSink",
      "Effect": "Allow",
      "Action": [
        "kms:GenerateDataKey"
      ],
      "Resource": [
        "<outputStreamKeyArn>"
      ]
    }
```

## Amazon MSK 叢集
<a name="how-zeppelin-iam-msk"></a>

若要授與 Amazon MSK 叢集的存取權，可以授與叢集 VPC 的存取權。如需存取 Amazon VPC 的政策範例，請參閱 [VPC 應用程式許可](https://docs.aws.amazon.com/managed-flink/latest/java/vpc-permissions.html)。
