Hi there,

I have a general question (GCP):
• I have a Cloud Run service and this service is using a Docker image from GCR
• The image is built from a Cloud Build trigger (also created via Pulumi)
• Correct me if I am wrong but there is no way to actually trigger the Cloud Build pipeline after creation (only manually)
I am trying to find what is the best way to:
1. Create the Cloud Build Trigger (if doesn’t exist)
2. Create the Cloud Run service w/ a dummy image (e.g. `<http://gcr.io/cloudrun/hello|gcr.io/cloudrun/hello>`) if the service doesn’t exist, *or* the actual GCR image otherwise).
3. Trigger the pipeline manually so that the GCR image is generated.
4. When running `pulumi up` later on, I obviously don’t want to override the last revision of the service with the dummy image if the service is already created and using the proper image.
The solutions I was thiking of are the following:
1. Checking if the service already exists with `GetService` -&gt; the issue is that it’s requiring an ID, so I can’t get the service until it’s created.
2. Using an input variable to differentiate the first time I run `pulumi up``   from the later “updates” -&gt; I used this solution with Terraform but I find it a bit dangerous and error-prone.
Any idea what the best way to do something like this would be?

Thanks
