# Kubernetes

## Definition

Kubernetes (K8s) 是 Google 开源的**容器编排平台**，用于自动化容器化应用的部署、扩缩容和管理。是云原生 (Cloud-Native) 架构的核心基础设施，也是 Agentic AI 自主修复 (Self-Healing) 的主要目标环境。

## Aliases

- K8s
- Kubernetes
- Container Orchestration Platform

## Major Cloud Implementations

| Provider | Service | Description |
|----------|---------|-------------|
| AWS | EKS (Elastic Kubernetes Service) | 托管 Kubernetes on AWS |
| GCP | GKE (Google Kubernetes Engine) | 托管 Kubernetes on GCP |
| Azure | AKS (Azure Kubernetes Service) | 托管 Kubernetes on Azure |

## Kubernetes Self-Healing Capabilities

Kubernetes 原生提供基础 Self-Healing 能力：

```yaml
# Kubernetes Self-Healing 原生机制
apiVersion: apps/v1
kind: Deployment
spec:
  replicas: 3
  strategy:
    type: RollingUpdate
  template:
    spec:
      terminationGracePeriodSeconds: 30
# 内置机制:
# - 自动重启失败的容器
# - 替换不健康的 Pod
# - 滚动更新确保服务可用
```

Agentic AI 在原生能力基础上提供**更高级的自我修复**：

| 能力 | Kubernetes 原生 | Agentic AI Enhanced |
|------|---------------|-------------------|
| Pod 重启 | ✅ 自动重启崩溃容器 | ✅ 智能分析根因 + 预防性重启 |
| 扩缩容 | ✅ HPA 基于指标 | ✅ 预测性扩缩容 |
| 节点恢复 | ✅ 节点故障迁移 | ✅ 主动健康检查 + 预防性迁移 |
| 配置修复 | ❌ 需人工介入 | ✅ AI 自动修正 ConfigMap/Secret |

## Example

> An AI agent monitoring AWS EKS clusters detects high CPU usage due to a rogue pod:
> - Pod `payment-service-v2-abc123` CPU usage: 95%
> - AI correlates with recent deployment timestamp
> - AI identifies: Memory leak in new version
> - AI Actions:
>   1. Scale deployment to 3 replicas (distribute load)
>   2. Create rollback ticket
>   3. Notify team via Slack
>   4. Auto-rollback after approval
