LanguageProject Introduction
Summary
Argo Rollouts is a Kubernetes controller and set of CRDs (Custom Resource Definitions) that provides enhanced deployment capabilities, offering progressive delivery strategies beyond the standard rolling updates.
Problem Solved
Traditional Kubernetes deployments (Deployment kind) lack fine-grained control over rollouts, making strategies like canary or blue/green difficult to implement safely and automatically. Manual interventions are often required for monitoring and progressive promotion or rollback.
Core Features
Blue/Green Deployment Strategy
Implement Blue/Green deployments with traffic routing controlled by services or ingress.
Canary Deployment Strategy
Perform controlled gradual rollouts to a subset of users with manual or automated promotion.
Canary Analysis
Automate analysis of canary deployments based on metrics from monitoring systems before promoting.
Traffic Shaping Integration
Integrate with popular ingress controllers and service meshes for traffic shaping.

使用场景
Argo Rollouts is ideal for scenarios requiring phased rollouts, automated verification before promotion, and the ability to quickly and safely revert to a previous version.
场景一：自动化金丝雀分析部署
Details
Deploy a new version to a small percentage of pods/traffic and monitor metrics (e.g., error rates, latency) from monitoring systems like Prometheus or Datadog. If metrics are healthy, automatically promote the new version.
User Value
Significantly reduce the risk of widespread outages by catching issues early during a phased rollout, based on actual application performance metrics.
场景二：零停机蓝绿部署
Details
Deploy a new version alongside the old one, switch all traffic to the new version instantly, and if issues arise, switch traffic back to the old version just as quickly.
User Value
Achieve near-zero downtime deployments and instant rollback capability, ensuring application availability during updates.
场景三：手动控制的渐进式发布
Details
Manually control the progression of a new version rollout, promoting batches of pods/traffic only after manual verification steps or approval gates.
User Value
Provide human oversight and control over critical application releases, combining automation with necessary manual checkpoints.
