05/25/2021, 4:31 PMI'm having a hard time getting values out of terraform remote state (I'm using the tf cloud backend).
Working from the example here: https://www.pulumi.com/docs/guides/adopting/from_terraform/ - is there a canonical way to simply get the map of outputs from the remote state into a Go object so I can interpolate them into other resources?

hmmm Ive never used this: did you see the examples here?

05/25/2021, 5:12 PMmaybe this is a fundamental misunderstanding on my part, or my relative inexperience with Go - all I'm trying to do is get a list of subnet IDs from tf remote state into a
[]string Copy code
publicSubnetIds := tfNetState.Outputs.ApplyT(func(args interface{}) ([]string, error) {
ids := args.(map[string]interface{})["public-subnet-ids"].([]interface{})
subnetIds := make([]string, len(ids))
for i, v := range ids {
subnetIds[i] = v.(string)
}
return subnetIds, nil
}).(pulumi.StringArrayOutput)ambitious-salesmen-39356
05/25/2021, 5:13 PMShould I not then just be able to
Copy code
for _, v := range publicSubnetIds {
fmt.Printf("id: %s", v)
}ambitious-salesmen-39356
05/25/2021, 5:18 PMThis is what I mean when I say I feel I'm missing something basic 😅

@ambitious-salesmen-39356 you need to range through the IDs inside the apply

in your case,
publicSubnetIdsa

05/25/2021, 5:28 PMright now just a print statement so I can make sure I'm getting values out =D

05/25/2021, 5:28 PMI'm just trying to figure out how to work with tf state

so, some pseudo code
Copy code
publicSubnetIds := tfNetState.Outputs.ApplyT(func(args interface{}) ([]string, error) {
// you can print each value here, because the value is resolved
fmt.Println(id)
}).(pulumi.StringArrayOutput)billowy-army-68599

ultimately what I think you're going to want to do is:
Copy code
var awsPublicSubnets []ec2.Subnet
publicSubnetIds := tfNetState.Outputs.ApplyT(func(args interface{}) ([]string, error) {
// do an append inside the apply
}).(pulumi.StringArrayOutput)a

05/25/2021, 5:33 PMthat makes sense.
