CI/CD Pipeline Diagrams

Document your CI/CD pipelines with Mermaid flowcharts. Visualize build stages, test suites, deployment environments, approval gates, and rollback procedures. Since Mermaid renders in GitHub, your pipeline docs live right next to your pipeline code.

Why Use Mermaid

  • Pipeline visualization — See all stages, dependencies, and parallel jobs at a glance
  • Onboarding — New DevOps engineers understand the deployment flow immediately
  • Change documentation — Update pipeline diagrams alongside pipeline-as-code changes
  • Approval gates — Clearly show manual approval steps and rollback procedures
  • Environment mapping — Visualize staging → production promotion paths

Frequently Asked Questions

More Use Cases

Database Schema Diagrams
Visualize your database schema with Mermaid ER diagrams. Import SQL CREATE TABLE statements directly or write Mermaid syntax to define entities, attributes, primary keys, foreign keys, and relationships. Perfect for database design, documentation, and migration planning.
Microservices Architecture Diagrams
Document your microservices architecture with Mermaid flowcharts. Visualize service dependencies, API gateways, message queues, databases, and communication patterns. Diagrams as code means your architecture docs live alongside your code and stay up-to-date.
API Documentation Diagrams
Document your APIs visually with Mermaid. Sequence diagrams show request/response flows between clients and services. Flowcharts illustrate authentication flows and error handling. ER diagrams define your data models. All rendered directly in your GitHub or GitLab docs.
System Design Diagrams
Visualize system designs with Mermaid for architecture reviews, technical interviews, and documentation. Use flowcharts for high-level architecture, sequence diagrams for data flows, and C4 diagrams for hierarchical decomposition. Text-based diagrams iterate faster than whiteboard drawings.
