[ceph-users] Deploy rgw different version using cephadm

Hello Recently I deployed a ceph cluster (version: reef) in my lab and after that, I deployed RGW using this manifest: service_type: rgw service_id: lab-object-storage placement: label: rgw count_per_host: 1 spec: rgw_frontend_port: 8080 Now I have a rgw container. the docker image is: quay.io/ceph/ceph (latest version) My question is: Is there any way to change rgw image version? How can I downgrade rgw version using cephadm? Thanks.
