This requires a doc change. In the meantime, all the Docker options are now available as part of group_vars/{all,mons,osds}.yml.sample There is a docker section at the end of each file so cp all these files like this: cp group_vars/all.yml.sample group_vars/all.yml cp group_vars/mons.yml.sample group_vars/mons.yml cp group_vars/osds.yml.sample group_vars/osds.yml
Closing this bug as the documentation has been published with the release
