Necessary steps (sample):

ceph dashboard set-rgw-api-access-key $(cat access_cephdash)
ceph dashboard set-rgw-api-secret-key $(cat secret_cephdash)
ceph dashboard set-rgw-api-host ceph_endpoint.ciberterminal.net
ceph dashboard set-rgw-api-port 80
ceph mgr module disable dashboard
ceph mgr module enable dashboard

accesscephdash and secretcephdash comes from the radosgw-admin command

Run:

sudo ceph mgr services

And you'll obtain the url:

avmlp-osm-001 /etc/ceph # ceph mgr services
{
    "dashboard": "https://avmlp-osm-002.ciberterminal.net:8443/"
