CI/CD Pipeline

A complete CI/CD pipeline diagram showing source, build, test, and deployment stages for automated software delivery.

5 min read

Free Template

A well-documented CI/CD pipeline is essential for reliable software delivery. This template diagrams the complete pipeline from source code commit through build, automated testing, staging deployment, and production release. It covers both continuous integration (automated build and test on every commit) and continuous delivery (automated deployment to staging with manual or automated promotion to production). Use it to document your existing pipeline or design a new one.

Pipeline Stages Explained

The template breaks the pipeline into distinct stages, each with clear inputs and outputs.

  • Source: Code repository with branch protection and PR reviews
  • Build: Compilation, dependency resolution, and container image creation
  • Test: Unit tests, integration tests, security scans, and linting
  • Staging: Automated deployment to a staging environment for acceptance testing
  • Production: Deployment with canary, blue-green, or rolling update strategies

Branching and Release Strategies

The diagram shows how different branches flow through the pipeline. Feature branches trigger build and test stages, while merges to the main branch trigger full deployment to staging. Production deployments can be triggered by tags, manual approvals, or automated promotion after staging verification.

Quality Gates and Security

Each stage in the pipeline includes quality gates — automated checks that must pass before the pipeline continues. These include test coverage thresholds, static analysis rules, dependency vulnerability scans (SCA), and container image scanning. The template visualizes these gates to help teams understand what blocks a deployment.

Tool-agnostic — works for GitHub Actions, GitLab CI, Jenkins, or others

Who Should Use This Template
  • Documenting your team's deployment process for onboarding
  • Planning a new CI/CD pipeline for a greenfield project
  • Compliance documentation for audit requirements (SOC2, ISO 27001)
  • Identifying bottlenecks and optimization opportunities in existing pipelines

Frequently Asked Questions
Is this template specific to a CI/CD tool like GitHub Actions or Jenkins?

No. The template is tool-agnostic and focuses on pipeline stages and flow. You can annotate nodes with your specific tool (GitHub Actions, GitLab CI, Jenkins, CircleCI, etc.) after creating the diagram.

Can I add infrastructure-as-code deployment?

Yes. Add Terraform, CloudFormation, or Pulumi nodes to the deployment stages to document how infrastructure changes are applied alongside application deployments.

How do I represent multiple environments?

The template shows staging and production environments. You can add additional environment nodes (dev, QA, pre-prod) and connect them to show the promotion path.
