@Marvin how do i migrate from

GCS

to

GcsBucket

? I currently have:

def get_storage_block(self) -> GCS:
        return GCS(
            bucket_path=f"prefect2-flow-storage-{self.gcp_project}",
            project=self.gcp_project,
        )

To migrate from the

GCS

storage block to using the

GcsBucket

storage block in Prefect 2.x, you'll need to change the way you initialize the storage and interact with GCS. Based on the search, here's an updated version of your current method using `GcsBucket`:

python
from prefect_gcp.cloud_storage import GcsBucket

def get_storage_block(self):
    gcs_bucket = GcsBucket(bucket_name=f"prefect2-flow-storage-{self.gcp_project}")
    return gcs_bucket

In this updated method,

GcsBucket

is instantiated directly with the

bucket_name

argument. If you need more than just the bucket, you would typically load any additional settings or credentials required. You can find more examples and information on how to use

GcsBucket

in the Prefect GCP integration documentation. Please note the links to further examples were not directly useful for migration, but the information was extracted from the Prefect GCP documentation excerpt provided.

@Marvin is the gcp project inferred using

GcsBucket

?

Yes, the GCP project can be inferred when using

GcsBucket

. If the project is not provided explicitly, it will be inferred from the credentials or the local environment. Here's an excerpt from the Prefect GCP documentation:

project: Optional[str]

The GCP project the bucket belongs to. If not provided, the project will be inferred from the credentials or the local environment.

This means you do not need to specify the

project

if your environment is set up with the necessary GCP project context.

@Marvin when i use

GcsBucket

, only the files in my current directory are uploaded to GCS, but not directories (with files)

To upload entire directories (with files) to Google Cloud Storage using the

GcsBucket

class, you would use the

put_directory

method. This method uploads a directory from a given local path to the configured GCS bucket. Here's an excerpt from the Prefect GCP documentation:

put_directory

async

Uploads a directory from a given local path to the configured GCS bucket in a given folder.

Unfortunately, the documentation excerpts provided do not give a full example. However, based on the information available, you can deduce a likely usage pattern for the

put_directory

method:

python
from prefect_gcp.cloud_storage import GcsBucket

# Assuming 'gcs_bucket' is your initialized GcsBucket instance.
gcs_bucket = GcsBucket.load("my-bucket")
local_directory_path = "/path/to/your/local/directory"
gcs_folder_path = "folder/in/gcs/where/files/should/go"

# Uploads the local directory to the specified folder in GCS bucket
gcs_bucket.put_directory(local_directory_path, gcs_folder_path)

Replace

local_directory_path

with the path to the directory you want to upload, and

gcs_folder_path

with the path within the GCS bucket where you want to place the content of that directory. You may need to refer to the source code or additional documentation of

prefect-gcp

for more detailed usage instructions or examples if necessary.
