示例 1：创建 IAM 角色

以下 create-role 命令将创建一个名为 Test-Role 的角色并对其附加信任策略。

aws iam create-role \
    --role-name Test-Role \
    --assume-role-policy-document file://Test-Role-Trust-Policy.json

输出：

{
    "Role": {
        "AssumeRolePolicyDocument": "<URL-encoded-JSON>",
        "RoleId": "AKIAIOSFODNN7EXAMPLE",
        "CreateDate": "2013-06-07T20:43:32.821Z",
        "RoleName": "Test-Role",
        "Path": "/",
        "Arn": "arn:aws:iam::123456789012:role/Test-Role"
    }
}

信任策略在 Test-Role-Trust-Policy.json 文件中定义为 JSON 文档。（文件名和扩展名没有意义。） 信任策略必须指定主体。

要将权限策略附加到角色，请使用 put-role-policy 命令。

有关更多信息，请参阅《Amazon IAM 用户指南》中的创建 IAM 角色。

示例 2：创建具有指定最长会话持续时间的 IAM 角色

以下 create-role 命令将创建一个名为 Test-Role 的角色，并将最长会话持续时间设置为 7200 秒（2 小时）。

aws iam create-role \
    --role-name Test-Role \
    --assume-role-policy-document file://Test-Role-Trust-Policy.json \
    --max-session-duration 7200

输出：

{
    "Role": {
        "Path": "/",
        "RoleName": "Test-Role",
        "RoleId": "AKIAIOSFODNN7EXAMPLE",
        "Arn": "arn:aws:iam::12345678012:role/Test-Role",
        "CreateDate": "2023-05-24T23:50:25+00:00",
        "AssumeRolePolicyDocument": {
            "Version": "2012-10-17",
            "Statement": [
                {
                    "Sid": "Statement1",
                    "Effect": "Allow",
                    "Principal": {
                        "AWS": "arn:aws:iam::12345678012:root"
                    },
                    "Action": "sts:AssumeRole"
                }
            ]
        }
    }
}

示例 3：创建带有标签的 IAM 角色

以下命令将创建带有标签的 IAM 角色 Test-Role。此示例使用带有以下 JSON 格式标签的 --tags 参数标志：'{"Key": "Department", "Value": "Accounting"}' '{"Key": "Location", "Value": "Seattle"}'。或者，--tags 标志可与简写格式的标签一起使用：'Key=Department,Value=Accounting Key=Location,Value=Seattle'。

aws iam create-role \
    --role-name Test-Role \
    --assume-role-policy-document file://Test-Role-Trust-Policy.json \
    --tags '{"Key": "Department", "Value": "Accounting"}' '{"Key": "Location", "Value": "Seattle"}'

输出：

{
    "Role": {
        "Path": "/",
        "RoleName": "Test-Role",
        "RoleId": "AKIAIOSFODNN7EXAMPLE",
        "Arn": "arn:aws:iam::123456789012:role/Test-Role",
        "CreateDate": "2023-05-25T23:29:41+00:00",
        "AssumeRolePolicyDocument": {
            "Version": "2012-10-17",
            "Statement": [
                {
                    "Sid": "Statement1",
                    "Effect": "Allow",
                    "Principal": {
                        "AWS": "arn:aws:iam::123456789012:root"
                    },
                    "Action": "sts:AssumeRole"
                }
            ]
        },
        "Tags": [
            {
                "Key": "Department",
                "Value": "Accounting"
            },
            {
                "Key": "Location",
                "Value": "Seattle"
            }
        ]
    }
}
