Hi all, Can someone help me with Pulumi and golang? How can I marshal

pulumi.StringOutput

and then use it in

ctx.Export

?

Hi, you should be able to use the

StringOutput

as is. An example with an S3 bucket,

Region

is a `StringOutput`:

ctx.Export("bucketRegion", bucket.Region)

If I need to export map of objects, I get the error:

./main.go:65:27: cannot use pairResources (variable of type map[pulumi.String]KeyPairExport) as pulumi.Input value in argument to ctx.Export: map[pulumi.String]KeyPairExport does not implement pulumi.Input (missing method ElementType)

or

error: an unhandled error occurred: program failed:
waiting for RPCs: json: error calling MarshalJSON for type pulumi.StringOutput: Outputs can not be marshaled to JSON

Well, that’s different from StringOutput 🙂 What’s KeyPairExport? You might use

pulumi.Output()

on your map, or you might need to

range

over the map and export the elements.

This is the example what I try to do:

type KeyPairExport struct {
	KeyName pulumi.StringOutput `pulumi:"key_name"`
	Id      pulumi.StringOutput `pulumi:"id"`
}

		pairResources := make(map[pulumi.String]KeyPairExport)
		for _, kp := range keyPairs {
			nkp, _ := ec2.NewKeyPair(ctx, kp.Name, &ec2.KeyPairArgs{
				KeyName:   pulumi.String(environment + "-key-pair-" + kp.Name),
				PublicKey: pulumi.String("ssh-rsa key"),
				Tags:      tags,
			})
			pairResources[pulumi.String(kp.Name)] = KeyPairExport{
				KeyName: nkp.KeyName,
				Id:      nkp.KeyPairId,
			}

		}

		ctx.Export("key-pairs", pairResources)

Is it possible to make it workable. That I can use dict of keys in other projects.

I believe

ctx.Export("key-pairs", pulumi.ToOutput(pairResources))

should work.

Thank you. I'll check.
