Configure proxy settings for gitlab to access internet for mirroring and notifications with helm

Hi,

I have an onpremise gitlab installation deployed on a Kubernetes cluster. I’m behind a proxy, so I was searching for the config options to set the proxy environment variables (http_proxy, https_proxy, no_proxy) like with the standalone container, when you add them to your gitlab.rb, restart and you’re done.
I can’t find how is done with helm. Is there a section on the helm chart docs that refers to this ?
Can I set the proxy settings for certain modules or do I need to use global.extraEnv.

Regards,
