# 示例： APIs 仅使用以下方式设置 AWS Control Tower 着陆区
<a name="walkthrough-api-setup"></a>

本示例演练是一份配套文档。有关解释、注意事项和更多信息，请参阅使用 [AWS Control Tower 入门](https://docs.aws.amazon.com//controltower/latest/userguide/getting-started-apis.html)。 APIs

**先决条件**

在创建 AWS Control Tower 登录区之前，您必须创建一个组织、两个共享账户和一些 IAM 角色。本教程包括以下步骤以及 CLI 命令和输出示例。

**步骤 1. 创建组织和两个必需的账户。**

```
aws organizations create-organization --feature-set ALL
aws organizations create-account --email example+log@example.com --account-name "Log archive account"
aws organizations create-account --email example+aud@example.com --account-name "Audit account"
```

**步骤 2：创建所需的 IAM 角色。**

`AWSControlTowerAdmin`

```
cat <<EOF >controltower_trust.json
{
  "Version": "2012-10-17",		 	 	 
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "controltower.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
EOF
aws iam create-role --role-name AWSControlTowerAdmin --path /service-role/ --assume-role-policy-document file://controltower_trust.json
cat <<EOF >ct_admin_role_policy.json
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "ec2:DescribeAvailabilityZones",
            "Resource": "*"
        }
    ]
}
EOF
aws iam put-role-policy --role-name AWSControlTowerAdmin --policy-name AWSControlTowerAdminPolicy --policy-document file://ct_admin_role_policy.json
aws iam attach-role-policy --role-name AWSControlTowerAdmin --policy-arn arn:aws:iam::aws:policy/service-role/AWSControlTowerServiceRolePolicy
```

`AWSControlTowerCloudTrailRole`

```
cat <<EOF >cloudtrail_trust.json
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "cloudtrail.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}
EOF
aws iam create-role --role-name AWSControlTowerCloudTrailRole --path /service-role/ --assume-role-policy-document file://cloudtrail_trust.json
cat <<EOF >cloudtrail_role_policy.json
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Action": "logs:CreateLogStream",
            "Resource": "arn:aws:logs:*:*:log-group:aws-controltower/CloudTrailLogs:*",
            "Effect": "Allow"
        },
        {
            "Action": "logs:PutLogEvents",
            "Resource": "arn:aws:logs:*:*:log-group:aws-controltower/CloudTrailLogs:*",
            "Effect": "Allow"
        }
    ]
}
EOF
aws iam put-role-policy --role-name AWSControlTowerCloudTrailRole --policy-name AWSControlTowerCloudTrailRolePolicy --policy-document file://cloudtrail_role_policy.json
```

`AWSControlTowerStackSetRole`

```
cat <<EOF >cloudformation_trust.json
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "cloudformation.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}
EOF
aws iam create-role --role-name AWSControlTowerStackSetRole --path /service-role/ --assume-role-policy-document file://cloudformation_trust.json
cat <<EOF >stackset_role_policy.json
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Action": [
                "sts:AssumeRole"
            ],
            "Resource": [
                "arn:aws:iam::*:role/AWSControlTowerExecution"
            ],
            "Effect": "Allow"
        }
    ]
}
EOF
aws iam put-role-policy --role-name AWSControlTowerStackSetRole --policy-name AWSControlTowerStackSetRolePolicy --policy-document file://stackset_role_policy.json
```

`AWSControlTowerConfigAggregatorRoleForOrganizations`

```
cat <<EOF >config_trust.json
{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": "config.amazonaws.com"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}
EOF
aws iam create-role --role-name AWSControlTowerConfigAggregatorRoleForOrganizations --path /service-role/ --assume-role-policy-document file://config_trust.json
aws iam attach-role-policy --role-name AWSControlTowerConfigAggregatorRoleForOrganizations --policy-arn arn:aws:iam::aws:policy/service-role/AWSConfigRoleForOrganizations
```

**步骤 3. 获取账号 IDs 并生成 landing zone 清单文件。**

以下示例中的前两个命令将您在**步骤 1** 中创建 IDs 的帐户的帐户存储到变量中。然后，这些变量有助于生成登录区清单文件。

```
sec_account_id=$(aws organizations list-accounts | jq -r '.Accounts[] | select(.Name == "Audit account") | .Id')
log_account_id=$(aws organizations list-accounts | jq -r '.Accounts[] | select(.Name == "Log archive account") | .Id')

cat <<EOF >landing_zone_manifest.json
{
   "governedRegions": ["us-west-1", "us-west-2"],
   "organizationStructure": {
       "security": {
           "name": "Security"
       },
       "sandbox": {
           "name": "Sandbox"
       }
   },
   "centralizedLogging": {
        "accountId": "$log_account_id",
        "configurations": {
            "loggingBucket": {
                "retentionDays": 60
            },
            "accessLoggingBucket": {
                "retentionDays": 60
            }
        },
        "enabled": true
   },
   "securityRoles": {
        "accountId": "$sec_account_id"
   },
   "accessManagement": {
        "enabled": true
   }
}
EOF
```

**步骤 4：使用最新版本创建登录区。**

 您必须使用清单文件和最新版本来设置登录区。此示例显示版本 3.3。

```
aws --region us-west-1 controltower create-landing-zone --manifest file://landing_zone_manifest.json --landing-zone-version 3.3
```

输出将包含一个 **arn** 和 **operationIdentifier**，如下面的示例所示。

```
{
    "arn": "arn:aws:controltower:us-west-1:0123456789012:landingzone/4B3H0ULNUOL2AXXX",
    "operationIdentifier": "16bb47f7-b7a2-4d90-bc71-7df4ca1201xx"
}
```

**第 5 步。（可选）通过设置循环来跟踪登录区创建操作的状态。**

要跟踪状态，请使用上一个 `create-landing-zone` 命令的输出中的 **operationIdentifier**。

```
aws --region us-west-1 controltower get-landing-zone-operation --operation-identifier 16bb47f7-b7a2-4d90-bc71-7df4ca1201xx
```

示例状态输出：

```
{
    "operationDetails": {
        "operationType": "CREATE",
        "startTime": "2024-02-28T21:49:31Z",
        "status": "IN_PROGRESS"
    }
}
```

您可以使用以下示例脚本来帮助设置一个循环，该循环会像日志文件一样反复报告该操作的状态。这样您就不需要一直输入命令了。

```
while true; do echo "$(date) $(aws --region us-west-1 controltower get-landing-zone-operation --operation-identifier 16bb47f7-b7a2-4d90-bc71-7df4ca1201xx | jq -r .operationDetails.status)"; sleep 15; done
```

**显示有关登录区的详细信息**

*步骤 1：找到登录区的 ARN*

```
aws --region us-west-1 controltower list-landing-zones
```

输出将包含登录区的标识符，如以下示例输出所示。

```
{
    "landingZones": [
        {
            "arn": "arn:aws:controltower:us-west-1:123456789012:landingzone/4B3H0ULNUOL2AXXX"
        }
    ]
}
```

*步骤 2：获取信息*

```
aws --region us-west-1 controltower get-landing-zone --landing-zone-identifier arn:aws:controltower:us-west-1:123456789012:landingzone/4B3H0ULNUOL2AXXX
```

您可能看到的示例输出如下所示：

```
{
    "landingZone": {
        "arn": "arn:aws:controltower:us-west-1:123456789012:landingzone/4B3H0ULNUOL2AXXX",
        "driftStatus": {
            "status": "IN_SYNC"
        },
        "latestAvailableVersion": "3.3",
        "manifest": {
            "accessManagement": {
                "enabled": true
            },
            "securityRoles": {
                "accountId": "9750XXXX4444"
            },
            "governedRegions": [
                "us-west-1",
                "us-west-2"
            ],
            "organizationStructure": {
                "sandbox": {
                    "name": "Sandbox"
                },
                "security": {
                    "name": "Security"
                }
            },
            "centralizedLogging": {
                "accountId": "012345678901",
                "configurations": {
                    "loggingBucket": {
                        "retentionDays": 60
                    },
                    "accessLoggingBucket": {
                        "retentionDays": 60
                    }
                },
                "enabled": true
            }
        },
        "status": "ACTIVE",
        "version": "3.3"
    }
}
```

**步骤 6. （可选）调用 `ListLandingZoneOperations` API 以查看更改登录区的任何操作的状态。**

要跟踪任何登录区操作的状态，您可以调用 [ListLandingZoneOperations](lz-api-examples-short.md#list-lz-operations-api-examples) API。
