Hi guys! I’m having some trouble understanding the difference between a

pulumi.Output

and a

Pulumi.OutputState

. I’m creating a config file ( in the form of a

pulumi.StringMap

) that includes various references to other pulumi resources, hence I used the

pulumi.All(arg1, arg2,...).ApplyT(func(args []interface{}) (pulumi.StringMap,error){...})

(as suggested in the docs,) which supposedly returns a

pulumi.Output

To be able to use it to create a kubernetes ConfigMap, i need to have a OutputState. What would the best way be to convert the output to the output state be, and what is the difference? I managed to convert the

pulumi.Output

config to a output state using

configMapData.Apply(func(x interface{}) (interface{}, error) { return x, nil }).OutputState

but this seems overly convoluted.

To be able to use it to create a Kubernetes ConfigMap, I need to have an OutputState

This should not be the case. You should be able to use an Output as an input to a ConfigMap. In general, you shouldn’t need to work with OutputState directly unless you are building your own new kinds of Outputs. Could you share the ConfigMap code perhaps?

Alright, thanks for your answer! After reading through the documentation of

ApplyT

, I understod that you can just cast the return value to a corresponding “registered” type. In my case i was returning a

pulumi.StringMap

, which apearantly doesn’t have a

pulumi.StringMapOutput

registered as its output type. If I return a

map[string]string

however, I’m able to cast the return value to a

pulumi.StringMapOutput

which

kubernetes.ConfigMapArgs

accepts. Is there any list of types with registered output types?

StringMapOutput should be registered as an output type https://github.com/pulumi/pulumi/blob/2351fc66cfe9b902aecc38718f2c70eaeb5372d4/sdk/go/pulumi/types_builtins.go#L7109
