      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).
The Vertex AI integration submodule provides a way to run ZenML pipelines in a Vertex AI environment.

            then a subdirectory of the artifact store will be used.
        encryption_spec_key_name: The Cloud KMS resource identifier of the
            customer managed encryption key used to protect the job. Has the form:
            `projects/<PRJCT>/locations/<REGION>/keyRings/<KR>/cryptoKeys/<KEY>`
            . The key needs to be in the same region as where the compute
            resource is created.
        workload_service_account: the service account for workload run-as
            account. Users submitting jobs must have act-as permission on this
            run-as account. If not provided, the Compute Engine default service
            account for the GCP project in which the pipeline is running is
            used.
        function_service_account: the service account for cloud function run-as
            account, for scheduled pipelines. This service account must have
            the act-as permission on the workload_service_account.
            If not provided, the Compute Engine default service account for the
            GCP project in which the pipeline is running is used.
        scheduler_service_account: the service account used by the Google Cloud
            Scheduler to trigger and authenticate to the pipeline Cloud Function
            on a schedule. If not provided, the Compute Engine default service
            account for the GCP project in which the pipeline is running is
            used.
        network: the full name of the Compute Engine Network to which the job
            should be peered. For example, `projects/12345/global/networks/myVPC`
            If not provided, the job will not be peered with any network.
        cpu_limit: The maximum CPU limit for this operator. This string value
            can be a number (integer value for number of CPUs) as string,
            or a number followed by "m", which means 1/1000. You can specify
            at most 96 CPUs.
            (see. https://cloud.google.com/vertex-ai/docs/pipelines/machine-types)
        memory_limit: The maximum memory limit for this operator. This string
            value can be a number, or a number followed by "K" (kilobyte),
            "M" (megabyte), or "G" (gigabyte). At most 624GB is supported.
        gpu_limit: The GPU limit (positive number) for the operator.

        -------------
        Before this method is called the `prepare_pipeline_deployment()` method
        builds a Docker image that contains the code for the pipeline, all steps
        the context around these files.
        Based on this Docker image a callable is created which builds
        container_ops for each step (`_construct_kfp_pipeline`). The function
        `kfp.components.load_component_from_text` is used to create the
        `ContainerOp`, because using the `dsl.ContainerOp` class directly is
        deprecated when using the Kubeflow SDK v2. The step entrypoint command
        with the entrypoint arguments is the command that will be executed by
        the container created using the previously created Docker image.
        This callable is then compiled into a JSON file that is used as the
        intermediary representation of the Kubeflow pipeline.
        This file then is submitted to the Vertex AI Pipelines service for
        execution.
        Args:
            deployment: The pipeline deployment to prepare or run.
            stack: The stack the pipeline will run on.
            environment: Environment variables to set in the orchestration
                environment.
        Raises:
            ValueError: If the attribute `pipeline_root` is not set and it

This is an intermediary representation of the pipeline which is then deployed to Vertex AI Pipelines service.
How it works:
Before this method is called the prepare_pipeline_deployment() method
builds a Docker image that contains the code for the pipeline, all steps
the context around these files.
Based on this Docker image a callable is created which builds
container_ops for each step (_construct_kfp_pipeline). The function
kfp.components.load_component_from_text is used to create the
ContainerOp, because using the dsl.ContainerOp class directly is
deprecated when using the Kubeflow SDK v2. The step entrypoint command
with the entrypoint arguments is the command that will be executed by
the container created using the previously created Docker image.
This callable is then compiled into a JSON file that is used as the intermediary representation of the Kubeflow pipeline.
This file then is submitted to the Vertex AI Pipelines service for execution.

ZenMLAwsSecurityCredentialsSupplier            (_DefaultAwsSecurityCredentialsSupplier)
        
    An improved version of the GCP external account credential supplier for AWS.
The original GCP external account credential supplier only provides rudimentary support for extracting AWS credentials from environment variables or the AWS metadata service. This version improves on that by using the boto3 library itself (if available), which uses the entire range of implicit authentication features packed into it.
Without this improvement, sts.AssumeRoleWithWebIdentity authentication is
not supported for EKS pods and the EC2 attached role credentials are
used instead (see: https://medium.com/@derek10cloud/gcp-workload-identity-federation-doesnt-yet-support-eks-irsa-in-aws-a3c71877671a).
