Currently, I am able to the same but with only one container by assigning static ip addresses to the container. Not sure how to implement this for multiple ones. Each rtu needs to have a diff IP adress and be associated with a ctrl unit. This ctrl unit is then connected to a network, linked to a gateway.
services:
rtu_a:
logging:
driver: "json-file"
options:
max-size: "200k"
max-file: "10"
image: ${REGISTRY_PREFIX}testbed/modbus${REGISTRY_TAG}
volumes:
- ./volume:/var/lib/my_volume
build:
context: .
cache_from:
- ${REGISTRY_PREFIX}modbus${REGISTRY_TAG}
- ${REGISTRY_PREFIX}modbus:${CI_COMMIT_REF_SLUG}
- ${REGISTRY_PREFIX}modbus:master
networks:
rtu-ctrl-net-a:
ipv4_address: 172.31.0.101
command: python3 rtu_unit.py "rtu_a"
ctrl_unit_a:
logging:
driver: "json-file"
options:
max-size: "200k"
max-file: "10"
image: ${REGISTRY_PREFIX}testbed/modbus${REGISTRY_TAG}
volumes:
- ./volume:/var/lib/my_volume
depends_on:
- rtu_a
networks:
rtu-ctrl-net-a:
ipv4_address: 172.31.0.102
command: python3 ctrl_unit.py rtu_a 1 "ctrl_unit_a"

Im not expert on this but I think you need to fix the network it self and connections
