Docker multi-container logging cap - docker

Question

I'm trying to cap the max size of docker's log files. Each container's log file should max out at 100M. So each container such as the edge, worker, etc should only be allowed to have a log file that is 100MB.
I tried to insert:
log_opt:
max-size: 100m
At the end of my docker-compose.yml file below but i'm getting an error.
Where should I place it?. Also when I place it inside each container definition I'm getting an error. I read the docker docs but no where does it say where exactly to place the option.
This is my docker-compose.yml file:
version: '2.0'
services:
ubuntu:
image: ubuntu
volumes:
- box:/box
cache:
image: redis:3.0
rabbitmq:
image: rabbitmq:3-management
volumes:
- ${DATA}/rabbitmq:/var/lib/rabbitmq
ports:
- "15672:15672"
- "5672:5672"
placements-store:
image: redis:3.0
command: redis-server ${REDIS_OPTIONS}
ports:
- "6379:6379"
api:

command: bundle exec puma -C config/puma.rb
env_file:

working_dir: /app

sneakers:

RACK_ENV: development
BUNDLE_PATH: /box

working_dir: /app

proxy:

ports:

volumes:
- ./config/nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf
volumes:
box:
# node_modules:
# bower_components:
# client_dist:
This is what I tried, for example inserting under the rabbitmq container:
version: '2.0'
services:
ubuntu:
image: ubuntu
volumes:
- box:/box
cache:
image: redis:3.0
rabbitmq:
image: rabbitmq:3-management
#volumes:
# - ${DATA}/rabbitmq:/var/lib/rabbitmq
ports:
- "15672:15672"
- "5672:5672"
log_opt:
max-size: 50m
placements-store:
image: redis:3.0
command: redis-server ${REDIS_OPTIONS}
ports:
- "6379:6379"
This is the error I get:
ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.rabbitmq: 'log_opt'
Tried to change log_opt: with options: and got the same error:
ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.rabbitmq: 'options'
Also the docker version is:
docker --version && docker-compose --version
Docker version 1.11.2, build b9f10c9/1.11.2
docker-compose version 1.9.0, build 2585387
UPDATE:
Tried using the logging option like the doc says (for version 2.0):
version: '2.0'
services:
ubuntu:
image: ubuntu
volumes:
- box:/box
cache:
image: redis:3.0
rabbitmq:
image: rabbitmq:3-management
#volumes:
# - ${DATA}/rabbitmq:/var/lib/rabbitmq
ports:
- "15672:15672"
- "5672:5672"
logging:
driver: "json-file"
options:
max-size: 100m
max-file: 1
placements-store:
image: redis:3.0
command: redis-server ${REDIS_OPTIONS}
ports:
- "6379:6379"
Getting the error:
ERROR: for rabbitmq Cannot create container for service rabbitmq:
json: cannot unmarshal number into Go value of type string ERROR:
Encountered errors while bringing up the project.
