Failed to add a proxy into clientset. #1246

Closed ziyanjiang98 closed 3 months ago

ziyanjiang98 commented 1 year ago

Package name: k8s.io/client-go v0.15.11

Issue: Due to the network structure, I need to add a proxy-url so that the HTTP requests from the client-go can be sent out to my clusters's IP address.

However, I met errors when using the following code

// Collect local kubeconfig file.
kubeConfigPath := filepath.Join(homedir.HomeDir(), ".kube", "config")
config, configErr = clientcmd.BuildConfigFromFlags("", kubeConfigPath)
...

// Add a transport to the config.
parsedURL, _ := url.Parse("<my_socks_proxy_url>")
ProxyURL := http.ProxyURL(parsedURL)
Transport := &http.Transport{
    Proxy: ProxyURL,
}
config.Transport = Transport

// Initialize the client.
kubeClient, clientErr := kubernetes.NewForConfig(config)
....

Then I got the following error: Create kube client fails: using a custom transport with TLS certificate options or the insecure flag is not allowed

Wondering if there is a way that I can fix it?

you probably want to set config.Proxy = http.ProxyURL(parsedURL) instead of constructing your own transport instance

Hi @liggitt , thanks for responding!

I do find the Proxy field in the latest package, but unfortunately there is no such field in k8s.io/client-go v0.15.11. Wondering if there is a workaround for the old version? Or if the proxy setting is only available for the latest version.

liggitt commented 1 year ago

it was added in v0.19.x

Sounds good! Will try to upgrade the package version in our repo. Thanks for the help!
