<p>It is unclear to me where to deploy the certmanager. I have deployed in a separate namespace, the cert has been created successfully, but the certificate cannot be found.</p>

<kubernetes><cert-manager>
Why can the certificate not be found by the Ingress Controller, while the certificate has been issued?
