Guillaume Desmottes 7a7cdc0797 gs: look for google_cloud_cpp_storage.pc
storage_client.pc was legacy and has been removed:
df6fa3611c (diff-bc35ad7c2fe631fd5578a06092412dba81c7ddd27bb25df7e17bb13771799afcL743)

No need to keep looking for storage_client.pc as a fallback as 1.25.0,
our minimum version, already ships google_cloud_cpp_storage.pc

Running the gs elements locally

When running from the command line or in a container running locally, simply set the credentials by exporting GOOGLE_APPLICATION_CREDENTIALS. If you are not familiar with this environment variable, check the documentation https://cloud.google.com/docs/authentication/getting-started Note that you can restrict a service account to the role Storage Admin or Storage Object Creator instead of the Project Owner role from the above documentation.

Running the gs elements in Google Cloud Run

Add the Storage Object Viewer role to the service account assigned to the Cloud Run service where gssrc runs. For gssink add the role Storage Object Creator. Then just set the service-account-email property on the element.

Running the gs elements in Google Cloud Kubernetes

You need to set GOOGLE_APPLICATION_CREDENTIALS in the container and ship the json file to which the environment variable points to.
