Description
User Story
As an operator, I would like to add proxy setting configurations to capi providers for the air-gapped environments.
Detailed Description
In air-gapped environment, cluster API provider pods might be deployed in air-gapped environment, and thus cannot talk to the infrastructure provider directly. In this scenario, a proxy server is typically deployed to enable the connectivity and audit the traffic that bypasses the firewall. It would be ideal if we can have a mechanism to plumb the proxy server configurations to the cluster API provider pods, so that they can be able to communicate with the infrastructure.
Anything else you would like to add: One approach I think think of is to have something like this:
HTTP_PROXY=xxx clusterctl init
The implementation should be similar to https://github.com/kubernetes/kubernetes/pull/84559.
