Can I use Argo Tunnel to connect my clusters together without exposing to the internet?

Question

Note that I'm newbie in Argo tunnel

I have several servers in different locations and only a set of them exposed to the internet. (Lets say there is two sets, backend and frontend.

I want to coonect from frontend to backend using Argo tunnel like they are on the same machine. Lets say, I have setup Nginx with proxy_pass http://backendde:8008! Now, backendde is a name for one of my backends. (or set an IP like 10.25.36.1)

Maybe, my question can be: "How can I expose one server to another using Argo tunnel?"

Note that I cant edit /etc/hosts (its a PaaS/kubernate) so, I have to assign a fixed local IP for each instance.

I have this

/root/cloudflared tunnel --no-autoupdate run --token $TUNNEL_TOKEN --protocol http2 $TUNNEL_NAME

and I dont know how to set a fixed IP for my instances and then call this IP from another server (with argo setup)

Thanks in advance

what you want to do is called "connecting private networks" on Argo tunnels lingo. You will need to deploy a "WARP" client on one end, and a cloudflared daemon on the other end, to be able to route traffic on the cloudflare edge network (without exposing the host to the internet).

See details here: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/private-net/connect-private-networks/

Thanks and the connection type will be WARP (wiregaurd)? Am I right? – Alireza Dec 19 '22 at 05:59
