Render Blueprints (render.yaml)

Blueprints define Render infrastructure as YAML (commonly render.yaml at the repo root). This skill focuses on authoring, wiring, projects/environments, previews, validation, and immutable fields. Heavy detail lives under references/.

When to Use

Apply this skill when the user:

• Creates or edits a render.yaml / Blueprint
• Wires databases, private services, or Key Value into app env vars
• Groups services with projects and environments
• Configures preview environments for pull requests
• Validates YAML against Render’s schema or CLI
• Asks what can or cannot change after a resource is created

For end-to-end deploy flows and MCP/CLI operations, see render-deploy. For env var strategy outside Blueprint syntax, see render-env-vars. For Docker-specific Blueprint fields, see render-docker.
