Description John Fulton 2018-01-05 16:10:30 UTC 
ceph-ansible's ceph_osd_docker_memory_limit is used when starting an OSD container as follows: 

`docker run ... --memory $ceph_osd_docker_memory_limit ... $osd_container_name`

As per https://bugzilla.redhat.com/show_bug.cgi?id=1527660, the field product manager is requesting this have a new default in TripleO of 1G not 3G.
Comment 3 Sébastien Han 2018-01-08 15:35:19 UTC 
This can be done in ceph-ansible.
Comment 12 Ken Dreyer (Red Hat) 2018-03-16 22:17:51 UTC 
The "containers: bump memory limit" commit has been in upstream's stable-3.0 branch since v3.0.25, so this is already GA to our customers in RHCEPH 3.
Comment 13 John Fulton 2018-03-22 00:22:41 UTC 
Looks good to me. An OSP12 overcloud deploy using fixed-in pacakge produced the desired results. Thank you.
