Overview
A builder pattern for configuring deployment properties (replica count, resources, autoscaling) and binding constructor arguments to produce a deployable application DAG node.
Description
Deployment Configuration and Binding uses a fluent builder pattern to specify all deployment properties — replica count, autoscaling config, route prefix, health check settings, and the target class. The .bind() step captures constructor arguments and produces an Application object (a DAG node) ready for deployment.
This two-phase pattern (configure then bind) separates deployment metadata from runtime arguments, enabling reusable deployment templates.
Usage
Use this principle after defining a deployment class and before deploying an application. Configure replica count, autoscaling, and resources, then bind constructor arguments.
Theoretical Basis
The builder pattern provides:
- Immutable configuration: Once bound, the configuration cannot change
- Fluent API: Method chaining for readable configuration
- DAG composition: The bind step produces a node that can be composed with other deployments
