Hi @FloSchick. Thanks for your PR.

I'm waiting for a cert-manager 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.

Could not lint: values.yaml and templates are not in sync

Also DCO check is failing. Please see https://cert-manager.io/docs/contributing/sign-off/.

[hawksight]

So I think that you need to include "value missing from templates: enabled" in this file.

This is because the value is not used in any actual helm template. Our linter calls this out. So we need that string to have it exempt from the linter. I worked that out by checking the cert-manager exemptions here.

@FloSchick - thank you for your contribution. I created another PR in #680 so that tests passed and commits were signed. This now merged and hopefully will go out in the next release. Thank you for taking a good first stab at the issue!
