Packer template for building a Debian-based AMI suitable for developing and running Python 3.4-based services

README.md

This is a Packer template for building a Debian-based AMI suitable for developing and running Python 3.4-based services. It uses a Debian 8 prerelease image as the base.

To build the AMI:

• Install Packer.
• Make sure your Amazon credentials are in ~/.aws/credentials.
• If using an AWS region other than Oregon, change region and source_ami in packer-template.json.
• Run packer build packer-template.json.
