how to build

if you want to build it from source, you need rust (super simple install)

https://www.rust-lang.org/tools/install

then just

sudo ./target/debug/kube-forwarder --kube-config /Users/kubeconfig.yaml

to forward traffic to appropriate POD. Sudo is required because of http is running on port 80. When forwarder is running, you can curl using kube-dns entries (curl -X GET http://your-app.namespace)

To make kube-forwarder working, you need to add necessary entries in /etc/hosts. To handle following request:

curl http://test-app1.namespace1/some/resource

add

127.0.0.1 test-app1.namespace1

in /etc/hosts

retry with bodies

I copied ReplyBody from https://linkerd.io/2021/10/26/how-linkerd-retries-http-requests-with-bodies/ and used it in kube-forwarder, so, proxied requests should be even more reliable.

how it works

basically that is how it works
