Do Cert-Manager in Kubernetes automatically renew the certificate after expiration Pls tell me

Question

Can somebody tell me if the Cert-Manager in Kubernetes automatically renew the certificate after expiration?

Answer 1

Yes, It will renew them automatically.

cert-manager is a Kubernetes add-on to automate the management and issuance of TLS certificates from various issuing sources.

It will ensure certificates are valid and up to date periodically, and attempt to renew certificates at an appropriate time before expiry.

If you are interested in knowing more about Kubernetes, then consider taking  CKA Certification Course.

will this happen without any specific configuration ? (no need to fill renewBefore/duration?)

if so, can you tell (and possibly share a link) that show the default values of how much time before expiration it is being renewed ?

thanks
