Access Cloud Storage buckets and files in JupyterLab
This page shows you how to mount a Cloud Storage bucket to the
JupyterLab interface of
your Vertex AI Workbench managed notebooks instance
so that you can browse files that are stored
in Cloud Storage. You can also open and edit files that are compatible
with JupyterLab, such as text files and notebook (IPYNB) files.
Overview
Vertex AI Workbench managed notebooks instances
include a Cloud Storage integration that lets you
mount a Cloud Storage bucket. This means you can browse the contents
of the bucket and work with compatible files from within
the JupyterLab interface.
You can access any of
the Cloud Storage buckets and files that your instance
has access to within the same project as
your managed notebooks instance.
Before you begin
This guide requires you to have access to
at least one Cloud Storage bucket in the same project
as your managed notebooks instance.
If you need to create a Cloud Storage bucket,
see Create buckets.
Next to your managed notebooks instance's name,
click Open JupyterLab.
Your managed notebooks instance opens JupyterLab.
Mount the Cloud Storage buckets and files
To mount and then access a Cloud Storage bucket, do the following:
In JupyterLab, make sure the
folderFile Browser tab
is selected.
In the left sidebar, click the
Mount
shared storage button. If you don't see the button, drag the right side
of the sidebar to expand the sidebar until you see the button.
In the Bucket name field, enter the Cloud Storage bucket name
that you want to mount.
Click Mount.
Your Cloud Storage bucket appears as a folder in the
File browser tab of the left sidebar. Double-click the folder to open
it and browse the contents.
