To be extra explicit suggest to spell it out e.g.

The monitor address is required to be provided for the rbd map command. Replace 192.168.X.Y with the mon host value from your clusters ceph.conf file.

The command also works for me (microceph (squid/stable) 19.2.0+snap3b53da1c21, ceph-common 19.2.0-0ubuntu0.24.04.2) without providing a monitor address:

$ sudo rbd map --image test_image_100G --name client.admin -k /var/snap/microceph/current/conf/ceph.keyring -c /var/snap/microceph/current/conf/ceph.conf -p block_pool /dev/rbd0
/dev/rbd0


.. code-block:: none

$ sudo rbd map \
--image bd_foo \
--name client.admin \
-m 192.168.29.152 \
-m 192.168.X.Y \
-k /var/snap/microceph/current/conf/ceph.keyring \
-c /var/snap/microceph/current/conf/ceph.conf \
-p block_pool \
