socks5 proxy

[Masber]

Hi, could you please share an example using kube-rs to create a kubernetes client using socks5 proxy?

It should just work out of the box with Client::try_default() provided you have the socks5 feature and a cluster configured using proxy-url in the kubeconfig.

If you need a custom client, try using the custom_client example but use a more specific connector rather than the default the example is using;

let mut base_connector = HttpConnector::new();
base_connector.enforce_http(false);
let proxy_connector = hyper_socks2::SocksConnector {
    proxy_addr: proxy_url.clone(),
    auth: None,
    base_connector,
};
let connector = config.rustls_https_connector_with_connector(proxy_connector)?;

See our internal builder setup for some more ideas there.

Example ssh Setup

A setup thing I usually test with is to socks proxy to another machine over ssh.

If you have a k3sbox, then grab its kubeconfig off that server, add proxy-url: socks5://0.0.0.0:3126 to clusters.cluster[0] and use that kubeconfig on your main machine.

add an entry in ~/.ssh/config for forwarding:

Host k3sbox
  HostName mymachinerunningk3s
  Port 8702
  User you
  IdentityFile ~/.ssh/k3s_id
  DynamicForward 3126

then keep a terminal maintaining an ssh k3sbox connection, and any kubectl or kube::Client stuff will then use the proxy-url to bounce through 0.0.0.0:3126 which will ssh forward through k3sbox and then use the regular server url on the other side.
