Learn

Practice-driven "learn by doing" paths — Each stage has practical projects and checkpoints

The OpenDDD Portal learning section provides four directions of learning roadmaps and four sets of practical recipes, helping you build real project capabilities from zero to one. All learning content originates from real practices in Open Domains.

Learning Roadmaps

Roadmap	Level	Core Path	Practical Project
Cloud Native DevOps	Intermediate	k3s → Helm → KubeVela → GitOps → Terraform	Build a production-grade k3s cluster
AI Agent Development	Advanced	Prompt Engineering → Agent Framework → Multi-Agent → RAG → Production	Build a customer service agent
DDD + Clean Architecture	Advanced	Clean Architecture → DDD → CQRS → Serverless Integration	Design procurement mall domain
One-Person Company	Expert	Opportunity Discovery → MVP Validation → Automated Operations → Scaling	Launch first business line

Practical Recipes

Ready-to-use operational recipes, each containing scripts + configs + docs, executable out of the box:

Recipe	Scenario	Contents
k3s + KubeVela	Lightweight K8s environment	Install scripts, image acceleration, Dashboard setup
Agent Building	AI Agent development	Agent framework, tool registration, memory system
WeChat Mini Program	Mini program development	Taro scaffold, cloud development, subpackage loading
DDD + Serverless	Backend architecture	Project scaffold, API design, deployment templates

Learning Method

1. Choose a roadmap → Determine learning direction and current stage
2. Read stage content → Understand core concepts and design decisions
3. Execute practical project → Use recipes or prompts to accelerate
4. Check checkpoints → Confirm mastery before moving to next stage
5. Preserve experience → Contribute new knowledge to the sharing system

Relationship with Open Domains

Each learning roadmap corresponds to one or more Open Domains:

Learning Roadmap	Corresponding Domain	Knowledge Source
Cloud Native DevOps	All-domain infrastructure	ProChain deployment practice
AI Agent Development	AI Agent domain	CustomerServiceAgent practice
DDD + Clean Architecture	ProChain	Procurement mall domain modeling
One-Person Company	Freelancing	Five-stage workflow practice
