Hi @wand3r3r. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

How about just adding

when: - http_proxy is defined

like the other Linux distribution cases instead of adding a new yum-specific option?

That case would be taken care of by the default already in place on line 78. In my use case, I need to define http_proxy for most of the environment. But, I manage the /etc/yum.conf and /etc/yum.repos.d separately due to an internally hosted Yum Proxy service I am required to use. This variable allows me to turn off the yum proxy. So that my preconfigured repo settings still work. Without it, in my environment, Kubespray fails to download any of the preinstall packages because it is trying to reach my internal hosted yum repo using the proxy.

Thanks for your explanation. I got an issue you are fixing.
I agree to add an option to skip using http_proxy for getting necessary OS packages.
One thing is I guess we will want to add other options when using different OS(like Ubuntu) because current option name is RHEL/CentOS specific.
How about more generic name like skip_http_proxy_on_os_packages or something?
It is fine to enable this option for RHEL/CentOS only at this time if don't want to take care of the other OS distributions.

I can do that
