How to use kube-cert-manager without using ingress resources

[jimgreenejr]

Hello All,
I would like to use kube-cert-manager, but without using an ingress resource as the trigger for renewing certificates. Basically we have some apps that have a custom nginx sidecar, and have no ingress controller configured that we could attach the annotations for kube-cert-manager to look at. Basically I can create the initial certificate objects easy enough, but how do I get cert-manager to use something other than an ingress resource for knowing what certs to look at? I am using the google dns provider.

Thanks

I maybe also am not understanding how it deals with renewals since I couldn't find a link in the docs (nor a setting for time for renewal)
