Indeed. Ansible is just a tool you should use for the fitting job. Afaik I only have to set a few variables and I do not have in the hundreds of services. But I would not mind looking at your Dockerfile to see how you prepare the image.
The ceph mailing list is 'full' of people using ansible, and then whining on what to do, and how to fix things when something does not work. Because they do not know how and where things are configured. All these 'easy' tools are like these higher level programming languages. They just lower the threshold for the 'bunglers' to enter an area of expertise, they were not able to enter before.

Probably the original poster wanted to set several env vars and use them as distinct RID values for multiple syncrepl directives. This is a common pattern for poor man's config management.
