feat: Add ability to configure multiple wilcard domains #14543

arsenetar · 2023-10-18T20:23:39Z

Proposed Changes

Update nscert reconciler to be able to create multiple wildcard certificates for any domain that is a wildcard
Update domain config to allow marking domains as having wildcard enable. The format of the change an implementation allows for prior usage without wildcard field to continue to function as it was.
Update references to config object as necessary to use new object format

Release Note

Add support for multiple wildcard certificate domains in domain config

Hi @arsenetar. Thanks for your PR.

I'm waiting for a knative 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

I believe unit test failures are legit - I think you need to update the fixtures to set the default domain is a wildcard

pkg/reconciler/nscert/nscert.go

pkg/reconciler/route/config/domain.go

dprotaso · 2023-11-17T21:14:48Z

pkg/reconciler/route/config/domain.go

+			internalConfig.Wildcard = true
+		}
+		c.Domains[k] = DomainConfig{
+			Selector: &LabelSelector{Selector: internalConfig.Selector},


nit: We could simplify LabelSelector now to be a type alias to map[string]string

Could there are methods on the LabelSelector type that are used right now. LabelSelector is an exported type with exported functions so not sure we would want to change those.

Hey @arsenetar just following up - next serving release is in two weeks.

arsenetar · 2024-01-12T16:36:55Z

@dprotaso Been trying to find time to work on this... haven't had a chance to slot this work in.

- Update nscert reconciler to be able to create multiple wildcard certificates for any domain that is a wildcard - Update domain config to allow marking domains as having wildcard enable. The format of the change an implementation allows for prior usage without wildcard field to continue to function as it was. - Update references to config object as necessary to use new object format

Change the boolean wildcard config to use a type field that could support other usage later. Update references and logic throughout.

Since this function bypasses the configuration loading it needs to set the default domain to Type of wildcard.

@dprotaso Took care of the quick changes, looking at the tests failures there seems to be a few things going on.

Found the one test fixture helper that bypassed the domain config loading function so that resolved some of the failures.

The test failure with two certs instead of one is due to it creating a new cert and not removing the old one since now there can technically be more than one. So that is a bug here if we want to keep the behavior similar to before, would need to modify the logic to remove any wildcard certs no longer in the list of wildcard domains.

Going to have to look at this failure more as:

   nscert_test.go:404: DNSNames should not be changed: (-want, +got) =   []string{
        - 	"*.subdomain.testns.svc.cluster.local",
        + 	"*.testns.svc.cluster.local",
          }

This might be the same as the other cleanup one... but not 100% sure at this point. I'll try to get back soon to rewriting the logic to make updates to remove the certs that are no longer matched by wildcard domains.

- Cleanup certs which no longer match a wildcard domains. - Return on first error instead of continuing (similar to prior behavior)

Change findNamespaceCert to use the labeled domain to find matching cert instead of the dnsNames in the cert. This seems to be the intended behavior to keep the cert associated with the entry in the domain config updated instead of potentially creating another.
