Cloud Run¶

Metadata¶

The container contract for Google Cloud Run specifies an internal server for metadata about the running service. This is useful for:

determining if your app is running on Cloud Run or somewhere else,
fetching values like the project_id which are required for structured logging
generating tokens that can be used to sign blobs without a private key.

To avoid the need to write requests to the internal server yet again, django_gcp provides a wrapper class for those query, exposing the results as properties. See django_gcp.metadata.metadata.CloudRunMetadata.

from django_gcp.metadata import CloudRunMetadata

meta = CloudRunMetadata()

# On your local machine, `meta.is_cloud_run` will be False, and accessing these
# attributes will raise a NotOnCloudRunError
if meta.is_cloud_run:
    print(meta.project_id)
    print(meta.project_number)
    print(meta.region)
    print(meta.compute_instance_id)
    print(meta.email)
    print(meta.token)
