将 Output<string> 转换为 AssumeRolePolicy 的字符串

Question

我正在尝试使用 F# 了解 pulumi，但我无法理解如何使用从一个资源发出的输出值最终进入另一个资源。这是我的具体情况：

let infra() =

        let adminsName = "admins"
        let current =
            Output.Create<System.Threading.Tasks.Task<GetCallerIdentityResult>>(GetCallerIdentity.InvokeAsync()).Apply<GetCallerIdentityResult>(fun x->
                x
                |> Async.AwaitTask
                |> Async.RunSynchronously
            )

        let adminRoleName = sprintf "%s-eksClusterAdmin" adminsName

        let adminRolePolicy =
            current.Apply(fun id ->
                @"{
                  ""Version"": ""2012-10-17"",
                  ""Statement"": [
                    {
                      ""Action"": ""sts:AssumeRole"",
                      ""Principal"": {
                        ""AWS"": ""arn:aws:iam::" + id.AccountId + @":root""
                      },
                      ""Effect"": ""Allow"",
                      ""Sid"": """"
                    }
                  ]
                }"
            )


        let adminsIamRole =
            Role (adminRoleName,
                RoleArgs(AssumeRolePolicy= (adminRolePolicy.Apply(fun x -> x)))
            )

我受到以下演练的极大启发，我正在尝试移植到 f#

https://www.pulumi.com/docs/guides/crosswalk/kubernetes/identity/#create-an-iam-role-for-admins

目前正在建设的项目告诉我：

iam.fs(47,45): error FS0001: The type 'Output<string>' is not compatible with the type 'Input<string>'
iam.fs(47,44): error FS0193: Type constraint mismatch. The type     'Output<string>'    is not compatible with type    'Input<string>'

如何使用 pulumi 将输出转换为输入？

Answer 1

有一个辅助函数io可以将输出转换为输入

AssumeRolePolicy = io adminRolePolicy

您需要引用Pulumi.FSharp NuGet 包。

参见io source 和a usage example。
