Hi @rubroboletus. 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.

dear bot, verify

Hmm would it be better to have a different value for HTTPS_PROXY?

[rubroboletus]

Hmm would it be better to have a different value for HTTPS_PROXY?

It depends, in 99% environments is same proxy for both.

[ayberk]

I think this is a good start. We can do it later if necessary.

[rubroboletus]

here is lot of ways, how to do it, from my point of view preffered one:

• name: HTTPS_PROXY
  value: {{ .Value.proxy.https_proxy | default .Value.proxy.http_proxy | quote }}
