kubectl logs nginx-ingress-controller-X -n nginx-ingress

kubectl describe certificates nexus-tls -n cert-manager

Message:               Certificate issued successfully
Reason:                CertIssued


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.

Once I followed this https://github.com/jetstack/cert-manager/blob/master/docs/tutorials/quick-start/index.rst#step-6---configure-lets-encrypt-issuer and deployed the issuers in the namespace of the app, it works
