Kubeseal removes the proxy-url flag from kubeconfig

[jvandijk]

Hello,

I use a proxy-url flag in my kubeconfig which was introduced in v1.19 of Kubectl (kubernetes/client-go#351) since we access the cluster via a Bastion host. Now the problem is that, if I add the proxy-url flag in the config and run kubeseal, the proxy-url flag gets removed from the kubeconfig which is very inconvenient since this requires to use the environment export HTTP_PROXY logic to have a working version of kubeseal. After running that you have to set the proxy-url again to have other tooling working again.

Reproduction steps:

• Add a proxy-url flag to kubeconfig for accessing the cluster via bastion
  -- manually in file before server : proxy-url: http://localhost:8888
  -- via kubectl : kubectl config set clusters.<name>.proxy-url "http://localhost:8888"
• Run kubeseal without any input
• see that proxy-url flag disappeared from the config

I can't seem to find a way to use my kubeconfig without it being tainted by the kubeseal command.

Versions used:

• kubeseal version : v0.16.0
• kubectl version : v1.19.7

A Pull Request (#705) was issued updating the client-go version to v0.22.1. This was released under version 0.17.2, also solving this issue.
