Been looking around in the docs but truly do not see anything about it. Anyone know how to use a created resource in a getter function? i.e. My example / what I am trying to do is get the

default_bucket

(from https://www.pulumi.com/docs/reference/pkg/gcp/appengine/application/) full details with

get_bucket

(https://www.pulumi.com/docs/reference/pkg/google-native/storage/v1/getbucket/)

# Get created bucket
self.full_bucket_details = storage.get_bucket(
    self.firestore_app.default_bucket,
    opts=pulumi.InvokeOptions(parent=self.firestore_app),
)

Does not work because it tries to get the bucket before the resource is created:

Exception: invoke of google-nativestorage/v1getBucket failed: invocation of google-nativestorage/v1getBucket returned an error: error sending request: googleapi: Error 400: Invalid bucket name: '{bucket}', invalid

are you trying to get a bucket that is being provisioned by the same stack?

Yes. Not possible?

keep in mind that pulumi is declarative. It is going to execute all of your pulumi code first before provisioning resources. When you want to get an existing resource it assumes that that resource exists outside of the currently running stack operation. I think what you might instead want is this function: https://www.pulumi.com/docs/reference/pkg/gcp/storage/bucket/#look-up

Ahhhhh thanks will give it a try

That might still not be right though because it looks like

application

is creating a bucket so that bucket isn't being directly managed by pulumi? When you call the

get_bucket

function that you linked you can pass in

InvokeOptions

which I believes takes in a

dependsOn

property? You could pass your

application

resource to the

dependsOn

and that might tell the API call to wait until the application is deployed before fetching the bucket

unfortunately,

depends_on

isn't an argument to

InvokeOptions

ah yea I might've been thinking of

parent

. Honestly though the output dependency tree should take care of this flow for you? for instance something like:

self.full_bucket_details = self.firestone_app.default_bucket.apply(bucketName => {
    return storage.get_bucket(
        bucketName,
        opts=pulumi.InvokeOptions(parent=self.firestore_app));
});

That worked! Thanks for the help

That won't work. That would be you declaring to provision a duplicate bucket and you would error. So this pattern would only work with "attachment" type resources, such as policy resources or similar. Can you use

DefaultObjectAccessControl

or

BucketIamPolicy

or

BucketAccessControl

to accomplish this? Those each are resource that attach to an existing bucket.

Yep. I figured as much just wanted to give it a try.
