End-to-End DevOps CI/CD Pipeline

Focus: Jenkins/GitHub Actions -> SonarQube/Test/Build -> ECR -> GitOps ArgoCD -> K8s Staging/Prod. Key areas: GitHub, GitHub Pull Requests, CODEOWNERS.

Use this as a block diagram of the system when explaining architecture.

Prompt

End-to-end DevOps CI/CD pipeline flow. Start with Code Commit triggering a Jenkins/GitHub Actions pipeline. Steps must include: Static Code Analysis (SonarQube), Unit Testing, Docker Image Build, and Pushing to a Container Registry (ECR). The Continuous Deployment phase should utilize a GitOps approach (e.g., ArgoCD) to synchronize the new image definition to a Kubernetes Cluster, separated into Staging and Production environments with manual approval gates.
Highlights
  • Key flows · CI flow: a code commit or PR triggers Jenkins/GitHub Actions, which runs Static Code Analysis in SonarQube, executes unit tests with coverage reporting, builds an immutable Docker image, and pushes the tagged image to Amazon ECR (optionally including SBOM/signing and registry scanning).
  • Layer details · Source Control & Trigger Layer: Modules include Code Repository (Git), Code Commit / PR Trigger.
  • Layer details · Continuous Integration (Build & Test): Modules include CI Orchestrator, Static Code Analysis (Quality Gate), Unit Testing, Docker Image Build.

Module responsibilities

Show all (13)
  • Source Control & Trigger Layer / Code Repository (Git): Store application source code and version history; Trigger CI on commits/PRs; Enforce code review and merge policies
  • Source Control & Trigger Layer / Code Commit / PR Trigger: Initiate automated pipeline execution; Differentiate PR validation vs mainline build; Provide metadata for build provenance
  • Continuous Integration (Build & Test) / CI Orchestrator: Run reproducible CI pipelines on each change; Coordinate quality gates and build steps; Publish build artifacts and metadata
  • Continuous Integration (Build & Test) / Static Code Analysis (Quality Gate): Detect vulnerabilities and maintainability issues early; Enforce quality thresholds before merge/release; Report findings back to PR status checks
  • Continuous Integration (Build & Test) / Unit Testing: Validate functional correctness of code units; Generate coverage artifacts for quality gates; Prevent regressions at merge time
  • Continuous Integration (Build & Test) / Docker Image Build: Create immutable deployable container images; Embed version/build metadata labels; Ensure consistent runtime packaging
  • Continuous Deployment (GitOps Release Management) / GitOps Manifests Repository: Declare desired state for each environment; Serve as the single source of truth for deployments; Enable auditable, reviewable releases via Git
  • Continuous Deployment (GitOps Release Management) / Image Definition Update (Promotion): Promote new build artifacts into environment configs; Ensure deployments reference immutable images; Gate releases through review/approval
  • Continuous Deployment (GitOps Release Management) / Argo CD (GitOps Controller): Synchronize Git desired state to Kubernetes; Provide deployment visibility and rollback; Prevent configuration drift
  • Continuous Deployment (GitOps Release Management) / Manual Approval Gates: Ensure controlled production releases; Enforce separation of duties; Reduce risk via staged promotion
  • Kubernetes Runtime Environments / Staging Kubernetes Cluster / Namespace: Validate releases in a production-like environment; Run smoke and integration checks; Provide safe rollback and troubleshooting
  • Kubernetes Runtime Environments / Production Kubernetes Cluster / Namespace: Serve live user traffic reliably; Support safe deployment strategies and fast rollback; Maintain operational stability and security
  • Kubernetes Runtime Environments / Runtime Observability & Security (Optional): Monitor application health and performance; Detect security issues and policy violations; Support incident response and compliance

Key flows

Show all (3)
  • CI flow: a code commit or PR triggers Jenkins/GitHub Actions, which runs Static Code Analysis in SonarQube, executes unit tests with coverage reporting, builds an immutable Docker image, and pushes the tagged image to Amazon ECR (optionally including SBOM/signing and registry scanning).
  • GitOps CD flow: after a successful image push, the pipeline updates the GitOps manifests repository (Helm/Kustomize) to reference the new image tag/digest for Staging; ArgoCD continuously reconciles Git desired state to the Staging Kubernetes environment and reports sync/health status.
  • Promotion with approval gates: once Staging validation passes, a manual approval gate (review-required PR / sync window) promotes the same immutable image reference to Production manifests; ArgoCD then synchronizes to the Production Kubernetes environment, enabling controlled rollout and rollback via Git history.
