Gcp
zenml.integrations.gcp
special
Initialization of the GCP ZenML integration.
The GCP integration submodule provides a way to run ZenML pipelines in a cloud
environment. Specifically, it allows the use of cloud artifact stores
and provides an io module to handle file operations on Google Cloud Storage
(GCS).
Additionally, the GCP secrets manager integration submodule provides a way to access the GCP secrets manager from within your ZenML Pipeline runs.
The Vertex AI integration submodule provides a way to run ZenML pipelines in a Vertex AI environment.

validate_gcp_secret_name_or_namespace(name)
Validate a secret name or namespace.
A Google secret ID is a string with a maximum length of 255 characters and can contain uppercase and lowercase letters, numerals, and the hyphen (-) and underscore (_) characters.

Given that we also save secret names and namespaces as labels, we are also limited by the limitation that Google imposes on label values: max 63 characters and must only contain lowercase letters, numerals and the hyphen (-) and underscore (_) characters

and a value that contains all its key-value pairs in JSON format.
* for an unscoped (i.e. legacy) Secrets Manager, this method creates
multiple Google secret entries for a single ZenML secret by adding the
secret name to the key name of each secret key-value pair. This allows
using the same key across multiple secrets. This is only kept for
