Telepresence 2 可以形象地比喻为： Kubernetes 项目开发的瑞士军刀！它能够将你的本地环境和远程的 Kubernetes 集群打通，让你的本地应用就像运行在集群内的 Pod 一样访问集群内的其他服务以及被集群内的其他服务访问。
Telepresence 2 会在远端集群中运行一个 agent 程序，同时修改本地的网络设置，通过一个加密隧道转发你本地计算机和远端集群的流量，让你的本地计算机就像运行在集群内的 Pod 一样，能够访问集群内的其他服务，也能够让你的本地应用被集群内的其他应用访问。
使用方法
测试本地访问远端服务
# 1. 连接远端集群 （失败请重试）
~ % telepresence connect --kubeconfig=xxx.kubeconfig
Launching Telepresence Root Daemon
Launching Telepresence User Daemon
Connected to context kubernetes-admin@kubernetes (https://x.x.x.x:6443)
# 2. 启动本地程序（此时就可以直接使用集群内的地址连接其他服务，这里以连接集群内的 mysql 服务为例）
~ % mysql -h mysql.default.svc.cluster.local -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 189970

# 3. 退出（清理环境）
~ % telepresence quit
Telepresence Root Daemon quitting... done
Telepresence User Daemon quitting... done
测试远端访问本地服务
# 1. 创建一个 deployment （已存在可跳过）
~ % kubectl create deployment example --image=datawire/hello-world
~ % kubectl expose deployment example --port=3000
# 2. swap deploymet 为本地服务，使用本地 3000 端口
~ % telepresence intercept example --port 3000
Using Deployment example
intercepted
Intercept name : example
State : ACTIVE
Workload kind : Deployment
Destination : 127.0.0.1:3000
Volume Mount Error: sshfs is not installed on your local machine
Intercepting : all TCP connections
# 3. 启动本地 3000 服务（假设本地有 react 项目监听 3000 端口）
~ % yarn start
# 4. 通过 service 访问本地服务
~ % curl example.default.svc.cluster.local:3000

注意：服务互访都需要通过 Service ，而不能直接访问 Endpoints 端点。
