Class WorkflowKustomizer

java.lang.Object
com.scivicslab.pojoactor.workflow.kustomize.WorkflowKustomizer
public class WorkflowKustomizer extends Object
Processes YAML overlays to generate customized workflows.

WorkflowKustomizer implements a Kustomize-like overlay system for POJO-actor workflows. It allows base workflows to be customized for different environments (development, staging, production) without duplicating code.

Key Features:

  • Strategic merge patches using vertexName as the matching key
  • Variable substitution with ${varName} syntax
  • Name prefix/suffix for workflow names
  • Vertex insertion with anchor-based positioning

Usage:

 WorkflowKustomizer kustomizer = new WorkflowKustomizer();
 Map<String, Object> result = kustomizer.build(Path.of("overlays/production"));
 String yaml = kustomizer.buildAsYaml(Path.of("overlays/production"));
