## 镜像拉取问题自动修复

### 识别条件
当遇到以下情况时，自动执行镜像缓存：
- Kubernetes Pod 状态为 `ImagePullBackOff` 或 `ErrImagePull`
- kubectl apply/create 返回镜像拉取错误
- docker pull 命令超时或失败

### 自动修复流程

#### 方案 1: 使用 kubectl wrapper（已安装）
```bash
# kubectl 命令会自动检测并修复
kubectl apply -f deployment.yaml
# → 自动检测 ImagePullBackOff
# → 自动缓存镜像
# → 自动更新 Deployment
```

#### 方案 2: 手动执行修复
```bash
# 自动修复 Deployment（推荐）
cd /Users/brunogao/work/codes/tools/macos/k8s
./cache-image.sh --update-deployment <namespace>/<deployment>

# 或单独缓存镜像
./cache-image.sh <image>:<tag>
```

### 重要提示
- ✅ kubectl 命令已自动启用修复功能
- ✅ 所有镜像会缓存到 `harbor.omniverseai.net:8080/library/`
- ✅ 支持 Docker Hub, GCR, Quay 等所有公共仓库
- ⚠️  遇到 ImagePull 问题时，kubectl wrapper 会自动处理
- ⚠️  如果 wrapper 失败，手动执行 `./cache-image.sh --update-deployment`

### 系统配置

已安装组件：
- ✅ OrbStack Registry Mirror (透明加速)
- ✅ kubectl wrapper (自动检测和修复)
- ✅ 后台监控服务 (持续监控)

查看监控日志：
```bash
tail -f /tmp/image-watch.log
```

停止监控：
```bash
launchctl unload ~/Library/LaunchAgents/com.k8s.image-watcher.plist
```
