What Sceptre is

Sceptre is a free tool for managing AWS CloudFormation stacks. It can create, update and delete stacks, retrieve stack information, and run commands across groups of related stacks. Designed for CI/CD pipelines, it is available as a command-line tool or Python module. It accepts templates in JSON, YAML, Jinja2 and Python DSLs such as Troposphere, with YAML configuration files. Templates can be loaded from local files, S3 or a web URL, and custom handlers can add other sources. Sceptre can pass one stack’s outputs into another’s parameters and infer dependency order. It also supports multiple AWS accounts and regions, concurrency limits for stack operations, and custom Python resolvers and hooks. By default, it uses the executing user’s AWS permissions, and it can use AWS profiles or IAM roles. Installation is available through pip, which assumes Python is installed, or through a Docker image. Sceptre requires AWS permissions for the CloudFormation operations being performed; some features, such as change sets or template buckets, need additional permissions.

Who it suits

Sceptre may suit teams managing CloudFormation stacks as part of CI/CD pipelines, including deployments across AWS accounts or regions. It is also suited to users who want a CLI or Python module and can configure the necessary AWS permissions.
