Weave Scope 是 Docker 和 Kubernetes 可视化监控工具。Scope 提供了至上而下的集群基础设施和应用的完整视图，用户可以轻松对分布式的容器化应用进行实时监控和问题诊断

- DaemonSet
weave-scope-agent，集群每个节点上都会运行的 scope agent 程序，负责收集数据。 - Deployment
weave-scope-app，scope 应用，从 agent 获取数据，通过 Web UI 展示并与用户交互。 - Service
weave-scope-app，默认是 ClusterIP 类型，可以通过edit svc，将 type 修改为 NodePort。
二 使用Scope
访问集群 Master IP地址，端口为NodePort端口
