Repository Setup

The easiest way to use these templates is with the Sceptre Package Manager.

Plugin Installation

In most cases you will want to add sceptre-package-template-handler to your requirements.txt file then either refresh your development environment or install with pip:

pip install -Ur requirements.txt

Alternatively you can install it directly:

pip install -U sceptre-package-template-handler

Repository Configuration

The repository information is best kept as a variable in Sceptre's root configuration file (sceptre/config/config.yaml):

sig_repo:
  name: sig-shared-sceptre
  base_url: https://github.com/sigdba/sig-shared-sceptre

Stack Configuration

To use a packaged template, use the following in place of template_path in your stack configuration file:

template:
  type: package
  name: EcsWebService
  release: 5
  repository: {{ sig_repo }}

Note that you can always find the latest release number on the release page.
