Then I exec docker-compose up -d to run my docker containers with
lables constraint:node==ozculster02
but the container still start up on ozculster01.
and this is my docker-compose.yml file :
version: '2'
services:
rabbitmq:
image: rabbitmq
ports:
- "5672:5672"
- "15672:15672"
config-service:
image: ozms/config-service
ports:
- "8888:8888"
volumes:
- ~/ozms/configs:/var/tmp/
- ~/ozms/log:/log
labels:
- "affinity:image==ozms/config-service"
eureka-service:
image: ozms/eureka-service
ports:
- "8761:8761"
volumes:
- ~/ozms/log:/log
labels:
- "constraint:node==ozcluster02"
environment:
- SPRING_RABBITMQ_HOST=rabbitmq

Answer 1

in compose v3 you should put constraint not in labels section, it shold be deploy section
services:
...
eureka-service:
...
deploy:
placement:
constraints:
- node.hostname==ozcluster02
