Debug Output

Panic Output

Expected Behavior

Terraform should recognize App Engine already exists and skip recreating it.

Actual Behavior

Terraform tries to create an App Engine, but fails with "googleapi: Error 409: This application already exists and cannot be re-created., alreadyExists".
Btw, Terraform doesn't look at $GOPATH/bin for new providers.

Steps to Reproduce

Create your GCP project and App Engine via GCP Console.

1. terraform init
2. terraform import google_project.test-dev test-dev
3. terraform plan
4. terraform apply

Hi @mkozjak, most of our resources don't let you use a "create" action when the resource already exists. Importing it into your state should work. I'm happy to entertain an argument about why app engine should behave differently than the rest, if you have one.

[mkozjak]

@danawillow Hi! Not sure if I reported okay, but I did import everything before trying plan/apply:

2. terraform import google_project.test-dev test-dev

So, I have created a project and an app engine initially without using terraform. Later on went with importing and trying apply. The rest is in the debug log.

@mkozjak Have you tried terraform import google_app_engine_application.test-dev test-dev?

[mkozjak]

@paddycarver Oh yes, sorry, I haven't tried that one. For some reason I thought it would pull everthing if i did just terraform import google_project.test-dev test-dev. Thanks!
