traefik can not route request to cluster ip inside K3S

[iWangJiaxiang]

Hi, thank you for such a useful tutorial!

I followed your article to setup my dedicated traefik gateway for home lab usage. However, when testing the whoami service, the traefik returned Gateway Timeout error.

The reason is my traefik server fetched the cluster ip 10.0.0.x of whoami service and used it as route destination. But the traefik server 192.168.x.x apparently can NOT access K3S virtual cluster network. So the request to whoami got Gateway Timeout error.

Is there any way to access k3s cluster network?
Am I missing any thing or misunderstanding your architecture?
I'd appreciate it if you could give me more hints or details. 😄

My environment is:

• VM1 : Running traefik server
• VM2 : Running k3s without traefik deployed
