Ceph Dashboard is now available at:

             URL: https://c1:8443/
            User: admin
        Password: ........

Enabling client.admin keyring and conf on hosts with "admin" label
Saving cluster configuration to /var/lib/ceph/7592ec0a-3c7a-11ee-b450-a0369f70d4f8/config directory
Enabling autotune for osd_memory_target
You can access the Ceph CLI as following in case of multi-cluster or non-default config:

        sudo /usr/sbin/cephadm shell --fsid 7592ec0a-3c7a-11ee-b450-a0369f70d4f8 -c /etc/ceph/ceph.conf -k /etc/ceph/ceph.client.admin.keyring

Or, if you are only running a single cluster on this host:

        sudo /usr/sbin/cephadm shell

Please consider enabling telemetry to help improve Ceph:

        ceph telemetry on

Bootstrap complete.
