• Create cluster issuer + certificate for whoami.cert.containous.cloudand powpow.cert.containous.cloud

kubectl apply -f cert-manager/

• Check that the certificate has been generated

kubectl describe certificate -n whoami whoami-cert
kubectl describe certificate -n whoami powpow-cert

• Check the certificate issuer with the command:

echo | openssl s_client -showcerts -servername whoami.cert.containous.cloud -connect whoami.cert.containous.cloud:443 2>/dev/null | openssl x509 -inform pem -text | grep 'Issuer'
