Creating Docker artifacts for a Google Cloud Storage bucket

El punto de entrada relevante es vetiver/attach_pkgs.py en las líneas 74-75; reproduce el flujo de board_gcs/prepare_docker e inspecciona cómo los protocolos ('gs', 'gcs') se asignan a los requisitos de paquetes. Se considera terminado cuando el vetiver_requirements.txt generado incluye gcsfs y el contenedor resultante se inicia.

Describe the bug

Seems to be a repeat of #165. I want to create Docker artifacts for a model stored on a GCS bucket, but the gcsfs package is not being listed in the vetiver_requirements.txt file so Docker cannot run the container.

To Reproduce

Create and store a model on a GCS bucket, and generate the required Docker artifacts. I used

import pandas as pd
from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split
from pins import board_gcs
from vetiver import VetiverModel, vetiver_pin_write, prepare_docker
from dotenv import load_dotenv
import os

# Load environment variables from .env file
load_dotenv()

# Load Palmer Penguins dataset
url = "https://raw.githubusercontent.com/allisonhorst/palmerpenguins/master/inst/extdata/penguins.csv"
penguins = pd.read_csv(url)

# Drop rows with missing values
penguins = penguins.dropna()

# Select features and target
X = penguins[["bill_length_mm", "bill_depth_mm", "flipper_length_mm", "body_mass_g"]]
y = penguins["body_mass_g"]

# Split into train and test sets
X_train, X_test, y_train, y_test = train_test_split(
    X, y, test_size=0.2, random_state=42
)

# Fit linear regression model
model = LinearRegression()
model.fit(X_train, y_train)

# Create Vetiver model
v = VetiverModel(model, "penguins-test", prototype_data = X_train)

# Store on board
board = board_gcs("info-4940-models/test/", cache=None, allow_pickle_read=True)
vetiver_pin_write(board, v)

# Create Docker artifacts
prepare_docker(
    board, 
    "penguins-test",
    path = "~/Desktop/penguins-test"
)

Note that prepare_docker() included this warning

/Users/bcs88/Projects/info-4940/assessments/.venv/lib/python3.13/site-packages/vetiver/attach_pkgs.py:77: UserWarning: required packages unknown for board protocol: ('gs', 'gcs'), add to model's metadata to export

I then built and ran the Docker container.

docker build -t penguins .
docker run -p 8080:8080 penguins

Which generated this output

ImportError: Please install gcsfs to access Google Storage

As expected since gcsfs is not listed in the vetiver_requirements.txt.

Expected behavior

I expected gcsfs to be automatically included in the requirements file. I can edit the file manually to add the requirement and then I can successfully build and run the container. But I thought #166 automated this step.

Additional context

Only thing that sticks out to me is

UserWarning: required packages unknown for board protocol: ('gs', 'gcs'), add to model's metadata to export

Which lists the protocols in reverse order compared to attach_pkgs.py.

https://github.com/rstudio/vetiver-python/blob/abb17c0fcdd9fa09e4dfe9e1d35aa02d35c67b91/vetiver/attach_pkgs.py#L74-L75

But I am primarily an R user, so I don't know if the order matters.
