Jupyter Notebook Contents Manager for AWS S3

Project description

Jupyter S3

Jupyter Notebook Contents Manager for AWS S3.


pip install jupyters3


To configure Jupyter Notebook to use JupterS3, you can add the following to your notebook config file.

from jupters3 import JupyterS3, JupyterS3SecretAccessKeyAuthentication
c = get_config()
c.NotebookApp.contents_manager_class = JupyterS3

and must also set the following settings on c.JupyterS3 in your config file.

Setting Description Example
aws_region The AWS region in which the bucket is located 'eu-west-1'
aws_s3_bucket The name of the S3 bucket. 'my-example-bucket'
aws_s3_host The hostname of the AWS S3 API. Typically, this is of the form s3-<aws_region> ''
prefix The prefix to all keys used to store notebooks and checkpoints. This can be the empty string ''. If non-empty, typically this would end in a forward slash /. 'some-prefix/'

You must also, either, authenticate using a secret key, in which case you must have the following configuration

from jupters3 import JupyterS3SecretAccessKeyAuthentication
c.JupyterS3.authentication_class = JupyterS3SecretAccessKeyAuthentication

and the following settings on c.JupyterS3SecretAccessKeyAuthentication

Setting Description Example
aws_access_key_id The ID of the AWS access key used to sign the requests to the AWS S3 API. ommitted
aws_secret_access_key The secret part of the AWS access key used to sign the requests to the AWS S3 API. ommitted

or authenticate using a role in an ECS container, in which case you must have the following configuration

from jupters3 import JupyterS3ECSRoleAuthentication
c.JupyterS3.authentication_class = JupyterS3ECSRoleAuthentication

where JupyterS3ECSRoleAuthentication does not have configurable options.

Differences from S3Contents

  • There are no extra dependencies over those already required for Jupyter Notebook. Specifically, there is no virtual filesystem library such as S3FS used, boto3 is not used, and Tornado is used as the HTTP client.

  • Checkpoints are also saved to S3, under the key <file_name>/.checkpoints/.

  • Multiple checkpoints are saved.

  • The event loop is mostly not blocked during requests to S3. There are some exceptions due to Jupyter Notebook expecting certain requests to block.

  • Uploading arbitrary files, such as JPEGs, and viewing them in Jupyter or downloading them, works.

  • Copying and renaming files don't download or re-upload object data from or to S3. "PUT Object - Copy" is used instead.

  • Authentication from EC2 instances using roles is not supported, but authentication using roles from ECS containers is supported.

  • Folders are created using a 0 byte object with key suffix / (forward slash). A single forward slash suffix is consistent with both the AWS Console and AWS AppStream.
