geofffranks/spruce — A BOSH template merge tool

Description and use

geofffranks/spruce is an open‑source command‑line utility that merges and interpolates BOSH deployment manifests using a simple, declarative template syntax. It enables developers to compose complex configuration files by overlaying multiple YAML fragments, handling conditional logic and variable substitution automatically. The tool is lightweight, language‑agnostic, and well suited for managing infrastructure-as-code workflows in BOSH environments.

Problem

geofffranks/spruce helps teams reuse working workflows and production presets instead of rebuilding them.

Outcome
