Sceptre is a tool to drive AWS CloudFormation. It automates away some of the more mundane, repetitive and error-prone tasks, allowing you to concentrate on building better infrastructure.

Sceptre's source code can be found here.

Features:

• Code reusability by separating a stack's template and its configuration
• Support for templates written in JSON, YAML or Python DSLs such as Troposphere
• Dependency resolution by passing of stack outputs to parameters of dependent stacks
• Environment support by bundling related stacks into logical groups (e.g. dev and prod)
• Environment-level commands, such as creating multiple stacks with a single command
• Fast, highly parallelised builds
• Built in support for working with stacks in multiple AWS accounts
• Infrastructure visibility with meta-operations such as stack querying protection
• Support for inserting dynamic values in templates via customisable resolvers
• Support for running arbitrary code as hooks before/after stack builds

Sceptre organises stacks into environments. Each stack is represented by a YAML configuration file stored in a directory which represents the environment. Here, we have two environments, prod and dev
