create a pool with a defined CRUSH map ruleset

how to use command to create a pool with a defined CRUSH map ruleset? For example, ceph osd pool create cow-pool 128 ???

For replicated pools:
ceph osd pool create {pool-name} [{pg-num} [{pgp-num}]] [replicated] [crush-rule-name] [expected-num-objects]
For erasure coded pools:
ceph osd pool create {pool-name} [{pg-num} [{pgp-num}]] erasure [erasure-code-profile] [crush-rule-name] [expected_num_objects] [–autoscale-mode=<on,off,warn>]
See the ceph documentation for more details: https://docs.ceph.com/en/latest/rados/operations/pools/.
