| name | Kubernetes编排 |
| description | 当实施Kubernetes编排时，分析集群架构设计，优化容器编排性能，解决K8s相关问题。验证资源配置，设计服务部署策略，和最佳实践。 |
| license | MIT |
Kubernetes是容器编排的事实标准。不当的K8s配置会导致资源浪费、性能问题和运维困难。在设计Kubernetes架构前需要仔细分析应用需求。
核心原则: 好的Kubernetes编排应该提升应用可用性和可扩展性，同时保证资源利用率。坏的编排会增加运维复杂性，甚至影响服务稳定性。
始终:
触发短语:
问题:
Pod资源配置不合理导致性能问题
错误示例:
- 没有设置资源请求和限制
- CPU和内存配置过高或过低
- 忽略资源使用监控
- 不合理的QoS类别
解决方案:
1. 设置合理的requests和limits
2. 实施资源监控和告警
3. 优化Pod调度策略
4. 配置合适的QoS类别
问题:
Kubernetes网络配置导致通信故障
错误示例:
- Service无法访问Pod
- Ingress配置错误
- 网络策略阻止通信
- DNS解析失败
解决方案:
1. 检查Service和Endpoint配置
2. 验证Ingress规则设置
3. 调整NetworkPolicy策略
4. 排查CoreDNS问题
问题:
持久化存储挂载失败或数据丢失
错误示例:
- PV和PVC配置不匹配
- 存储类选择错误
- 权限配置问题
- 数据备份策略缺失
解决方案:
1. 正确配置PV和PVC
2. 选择合适的StorageClass
3. 设置正确的访问权限
4. 实施定期备份策略
