S3PyPI is a CLI for creating a Python Package Repository in an S3 bucket.

An extended tutorial on this tool can be found here.

Getting started


Install s3pypi using pip:

pip install s3pypi

Setting up S3 and CloudFront

Before you can start using s3pypi, you must set up an S3 bucket for your Python Package Repository, with static website hosting enabled. Additionally, you need a CloudFront distribution for serving the packages in your S3 bucket to pip over HTTPS. Both of these resources can be created using the CloudFormation templates provided in the cloudformation/ directory:

aws cloudformation create-stack --stack-name STACK_NAME \
    --template-body file://cloudformation/s3-pypi.json \
    --parameters ParameterKey=AcmCertificateArn,ParameterValue=ACM_CERT_ARN \

Managing Your Server Certificates


Distributing packages

You can now use s3pypi to create Python packages and upload them to your S3 bucket. To hide packages from the public, you can use the --private option to prevent the packages from being accessible directly via the S3 bucket (they will only be accessible via Cloudfront and you can use WAF rules to protect them). If switching between private and public is not flexible enough, you can use the --acl option to directly specify the ACL. Alternatively, you can specify a secret subdirectory using the --secret option:

cd /path/to/your-project/
s3pypi --bucket mybucket [--private | --acl ACL] [--secret SECRET]

Installing packages

Install your packages using pip by pointing the --extra-index-url to your CloudFront distribution (optionally followed by a secret subdirectory):

pip install your-project --extra-index-url

Alternatively, you can configure the index URL in ~/.pip/pip.conf:

extra-index-url =


Currently there are no plans to add new features to s3pypi. If you have any ideas for new features, check out our contributing guidelines on how to get these on our roadmap.
