Cannot use existing ssl wildcard certificate for AutoDevOps auto deploy

Summary

Gitlab 12.10.3 integrate the kubenetes 1.15.9 cluster with following applications installed:

• Helm Tiller
• Ingress
• Cert-Manager
• Prometheus
• GitLab Runner

Run AutoDevOps pipeline for one project. In stage production, auto deploy will create a new ssl certificate from Let's Encrypt. We have got a wildcard certificate from Godaddy. We would like to use the existing wildcard certificate rather than create a new one.

What is current behavior

Auto deploy create a new certificate from Let's Encrypt

What is expected behavior

There is a way to config the existing wildcard certificate for auto deploy. Do not create any new certificate.
