运行kubevpn connect命令输出的是一下信息，请问下在哪里能看到环境变量信息呢。和这个文档的输出内容不一样https://www.kubevpn.cn/docs/blog/connect_mode/

Starting connect
Got network CIDR from cache
Use exist traffic manager
Forwarding port...
Connected tunnel
Adding route...
Configured DNS service
+----------------------------------------------------------+
| Now you can access resources in the kubernetes cluster ! |
+----------------------------------------------------------+

我的环境是这样的，使用EasyConnect VPN连接公司内网，可以正常启动本地服务，但是API请求会路由不到本地。这里我估计是因为EasyConnenct VPN是单向的。

所以，我这个场景能用kubeVPN路由到本地调试吗

直接在pod中执行env命令获取环境变量例如:

# 获取运行时依赖的环境变量
export KUBECONFIG=/var/folders/30/cmv9c_5j3mq_kthx63sb1t5c0000gn/T/342259381.kubeconfig
kubectl exec -it deployment/ry-server -n vke-system -c server -- env | pbcopy

可以使用kubevpn本地调试的哈

你看看直接在本地使用 datagrip 是否可以链接到mysql尼，直接链接 mysql pod或者service的ip就行。

了IP环境变量访问

Holinc19 commented 3 months ago

需要指定什么IP信息吗，比如：spring.cloud.inetutils.preferred-networks

现在本地IDEA服务启动了，但是呢，还是路由不进来。查看了一下注册中心上的服务，发现用的是本地电脑WiFi的IP，这个应该再网络上就是不通的吧

配置了vpn输出的环境变量以后，发现一个问题，服务启动以后会报错MySQL、Redis连接不上了，这种情况是要怎么处理呢。

MySQL、Redis是再开发环境上搭建的，配置了IP环境变量访问

使用 proxy模式，可实现K8S与本地网络互通，实现本地调试，配合--headers参数，可实现带指定请求头参数的流量打到本地服务。与connect 模式不同的是，connect 模式是本地单向访问K8S
