1. Introduction & Overview
Spinnaker is a powerful, open-source, multi-cloud continuous delivery (CD) platform that facilitates the safe and fast release of software. Designed for high-velocity development environments, it helps organizations modernize their software delivery pipelines while incorporating security, compliance, and operational checks.
Why Focus on Spinnaker in DevSecOps?
In DevSecOps, where security is integrated across the DevOps lifecycle, Spinnaker offers native support for:
- Automated deployments with policy gates
- Role-based access control (RBAC)
- Auditing and traceability
- Integration with CI, cloud providers, and secrets management tools
2. What is Spinnaker?
History and Background
- Created by Netflix to handle its own complex deployment needs.
- Open-sourced in 2015 and has since seen contributions from Google, Amazon, Microsoft, and others.
- Designed to deploy applications across multiple cloud environments such as AWS, GCP, Kubernetes, and more.
Relevance in DevSecOps
- Shift-left security: Enforces controls during deployment rather than after.
- Immutable infrastructure support: Deploys pre-approved, tested images.
- Audit and compliance tracking: Integration with monitoring and logging systems.
3. Core Concepts & Terminology
| Term | Definition |
|---|---|
| Pipeline | A sequence of deployment steps including tests, approvals, and deployment tasks |
| Stage | A single step in a pipeline (e.g., bake, deploy, manual judgment) |
| Bake | Creation of VM images or Docker containers from builds |
| Canary Deployment | Releases a small subset to monitor before full rollout |
| Cluster | Group of server groups within a region/account/environment |
| Application | Logical container grouping clusters, pipelines, and load balancers |
Spinnaker in DevSecOps Lifecycle
Spinnaker fits mainly in the CD (Continuous Delivery) and Release stages of the DevSecOps pipeline. It integrates security into:
- Image baking (via vulnerability scanning)
- Deployment gating (via policy-as-code)
- Manual approvals and security tests
4. Architecture & How It Works
Key Components
| Component | Purpose |
|---|---|
| Deck | UI frontend |
| Gate | REST API gateway |
| Orca | Orchestration engine managing pipelines |
| Clouddriver | Interfaces with cloud providers (AWS, GCP, Kubernetes, etc.) |
| Echo | Event and notification system |
| Rosco | Image bakery |
| Front50 | Stores application metadata and pipeline configs |
| Igor | Integrates CI tools like Jenkins, GitHub Actions |
| Fiat | Role-based access control and permissions |
Internal Workflow Description (Architecture Diagram Substitute)
- Trigger: CI tool (e.g., Jenkins) finishes a build → sends event to Spinnaker.
- Orca: Orchestrates pipeline execution across stages.
- Rosco: Bakes an image using a base OS + app artifact.
- Clouddriver: Deploys to target cloud provider.
- Fiat: Ensures user permissions are respected.
- Echo: Sends deployment notifications.
Integration Points
- CI Tools: Jenkins, GitHub Actions, GitLab CI
- Cloud Providers: AWS, GCP, Kubernetes, Azure
- Security: HashiCorp Vault, OPA (Open Policy Agent)
- Monitoring: Prometheus, Datadog, New Relic
5. Installation & Getting Started
Prerequisites
- Kubernetes cluster or local Docker environment
- Helm v3 (for Kubernetes)
- AWS/GCP credentials if deploying to cloud
- Git for pipeline configurations
Installation (Kubernetes-based via Helm)
# Add Spinnaker Helm repo
helm repo add spinnaker https://charts.spinnaker.io
# Create namespace
kubectl create namespace spinnaker
# Install Spinnaker
helm install spinnaker spinnaker/spinnaker --namespace spinnaker \
--set gate.service.type=LoadBalancer
Access Spinnaker UI
kubectl get svc -n spinnaker
Use the EXTERNAL-IP from deck service to open Spinnaker UI in your browser.
First Pipeline Example
- Create Application in Spinnaker UI.
- Add Pipeline:
- Trigger: Jenkins build or Git tag
- Bake Stage: Create image using Rosco
- Deploy Stage: Push to Kubernetes/AWS/GCP
- Manual Judgment Stage (optional): Add approval gate
6. Real-World Use Cases
Use Case 1: Multi-cloud Deployment with Security Scanning
- Scenario: Fintech deploying apps across AWS and GCP.
- Spinnaker bakes images using Rosco and runs security scans before deployment.
Use Case 2: Automated Canary Deployment with Rollback
- Scenario: E-commerce app testing new features on 5% of users.
- Monitors metrics using Prometheus; auto-rollbacks if latency increases.
Use Case 3: Deployment Gating Using OPA
- Scenario: Healthcare org enforcing HIPAA-compliant pipelines.
- OPA validates pipeline configuration and deployment targets before approval.
Use Case 4: Kubernetes App Deployment with RBAC
- Scenario: SaaS platform using Spinnaker to deploy microservices.
- Uses Fiat to restrict access by teams, automates container deploys to K8s.
7. Benefits & Limitations
Benefits
- Enterprise-ready CD platform
- Cloud-native and multi-cloud friendly
- Rich pipeline modeling and gating
- Strong integration ecosystem
- Policy enforcement and auditability
Limitations
- Complex setup and maintenance
- Resource-intensive (especially in Kubernetes)
- Steep learning curve for new teams
- UI performance issues under high load
8. Best Practices & Recommendations
Security
- Integrate vulnerability scanners into bake stages (e.g., Trivy, Clair).
- Use OPA for policy-as-code to enforce deployment rules.
- Secure secrets using HashiCorp Vault or cloud-native solutions.
Performance & Maintenance
- Scale components like Clouddriver for large clusters.
- Use Redis persistence and external databases for production.
Compliance
- Enable audit logging for all pipeline actions.
- Use manual judgment stages for high-risk deployments.
Automation
- Create reusable pipeline templates for standardization.
- Auto-generate pipelines via GitOps or Front50 API.
