To install the Katello main server with the custom certificates, run:

    foreman-installer --scenario katello \
                      --certs-server-cert "/root/server.crt" \
                      --certs-server-key "/root/server.key" \
                      --certs-server-ca-cert "/root/ca.pem"

To update the certificates on a currently running Katello installation, run:

    foreman-installer --scenario katello \
                      --certs-server-cert "/root/server.crt" \
                      --certs-server-key "/root/server.key" \
                      --certs-server-ca-cert "/root/ca.pem" \
                      --certs-update-server --certs-update-server-ca

  To use them inside a NEW $FOREMAN_PROXY, run this command:

      foreman-proxy-certs-generate --foreman-proxy-fqdn "$FOREMAN_PROXY" \
                                   --certs-tar  "~/$FOREMAN_PROXY-certs.tar" \
                                   --server-cert "/root/capsule_certs/server.crt" \
                                   --server-key "/root/capsule_certs/server.key" \
                                   --server-ca-cert "/root/ca.pem" \

  To use them inside an EXISTING $FOREMAN_PROXY, run this command INSTEAD:

      foreman-proxy-certs-generate --foreman-proxy-fqdn "$FOREMAN_PROXY" \
                                   --certs-tar  "~/$FOREMAN_PROXY-certs.tar" \
                                   --server-cert "/root/capsule_certs/server.crt" \
                                   --server-key "/root/capsule_certs/server.key" \
                                   --server-ca-cert "/root/ca.pem" \
                                   --certs-update-server
