# Spot Invaders
|
||||
|
||||
**Type:** EKS + EC2 Spot 容错混沌工程游戏
|
||||
|
||||
## Overview
|
||||
Spot Invaders 是一款基于 Amazon EKS 和 EC2 Spot 实例的容错混沌工程游戏,直观展示如何在 EKS 上运行具有弹性的应用,同时优化成本。游戏机制包括射击外星人(模拟 Pod 故障)和鲸鱼(触发 Spot 中断),生动展现即使在发生中断的情况下也能维持服务可用性的最佳实践。
|
||||
|
||||
## Game Mechanics
|
||||
- **射击外星人**:模拟 Pod 故障,展示应用容错能力
|
||||
- **射击鲸鱼**:触发 Spot 实例中断,演示 Spot 中断通知机制
|
||||
- **存活挑战**:在持续的 Pod 故障和 Spot 中断下维持游戏运行
|
||||
|
||||
## Key Lessons
|
||||
- Spot 实例可用于生产级有弹性要求的应用
|
||||
- 跨实例类型和可用区多样化是关键
|
||||
- EKS 提供内置 Spot 中断通知(2 分钟预警)
|
||||
- 自动化中断响应可实现零停机
