Hi Kenneth,

check the config db which image is set:

ceph config dump
WHO             MASK  LEVEL     OPTION                                VALUE     
                      RO
global                basic     container_image                       
docker.io/ceph/ceph:v15.2.9     *

Probably you have v15 tag configured which means orchestrator will fetch latest 
v15 image - so as of today this would be v15.2.9.

So either you change the setting in the config DB or you can do it like this if 
you have v15 configured:

- log in to the host that is going to be added beforehand
- get you preferred image:
docker pull ceph/ceph:v15.2.6
- retag it
docker tag ceph/ceph:v15.2.6 ceph/ceph:v15
- remove the original image
docker rmi ceph/ceph:v15.2.6
- add host as usual

orchestrator will use the configured v15 image which on the new host 
corresponds to v15.2.6

hope it helps

best,
tobi
