Hey all. Is there any way for me to get Pulumi to take control of a pre-existing resource on GCP?

You can read in existing resources and create new resources that depends on them easily - using

.get(...)

functions on each resource. Taking over ownership of existing resources ("adopting" them) is a little more involved and we don't currently have a fully first-class way to support it. See https://github.com/pulumi/pulumi/issues/1662 for tracking. @microscopic-florist-22719 may be able to update that issue with the set of steps that users can take to manually go through the adoption process?
