带来的新挑战 服务调度 状态存储 集群管理 成员管理 扩缩容 故障迁移 高可用 CoreOS 提出了 operator Deployment StatefulSet PV/PVC StorageClass ？？ 站在 Kubernetes 的肩膀上 An Operator is an application-specific controller that extends the Kubernetes Pod-T 0. 创建 CRD 3. 集群管理 2. 调度 pod Ceph MySQL-Operator 数据存储 分布式存储 • 使用 Ceph RBD，基于产品线 创建 StorageClass • 优点：可靠性高，容器漂移时 数据不变 • 缺点：读写延迟较高 本地存储 • 基于 Host Path Volumes • 优点：读写延迟低 • 缺点：单点数据，容器漂移时
