Deploy Gitlab Runner stack with docker swarm - docker

Question

I'm trying to deploy a gitlab runner stack in docker-compose above:
version: '3.8'
services:
dind:
image: docker:stable
deploy:
mode: replicated
placement:
constraints:
- "node.role==worker"
restart_policy:
condition: any
volumes:
- /var/lib/docker
command:
- --storage-driver=overlay2
networks:
- netrunner
runner:
image: gitlab/gitlab-runner:alpine
deploy:
mode: replicated
placement:
constraints:
- "node.role==worker"
restart_policy:
condition: any
volumes:
- ./gitlab/runner:/etc/gitlab-runner:Z
- /var/run/docker.sock:/var/run/docker.sock
environment:
- DOCKER_HOST=tcp://dind:2375
depends_on:
- dind
networks:
- netrunner
register-runner:
image: gitlab/gitlab-runner:alpine
deploy:
mode: replicated
placement:
constraints:
- "node.role==worker"
restart_policy:
condition: none
volumes:
- ./gitlab/runner:/etc/gitlab-runner:Z
command:
- register
- --non-interactive
- --locked=false
- --name=Docker Runner
- --executor=docker
- --docker-image=docker:stable
- --docker-volumes=/var/run/docker.sock:/var/run/docker.sock
environment:
- CI_SERVER_URL=https://gitlab.com/
- REGISTRATION_TOKEN=xxxxxxxxxxxxxx
networks:
- netrunner
networks:
netrunner:
driver: overlay
driver_opts:
foo: "1"
Then, with docker swarm initialized, I try the deployment with this pattern:
docker stack deploy --compose-file docker-compose.yml ci
After that, when I check services I get this:
$ docker stack services ci
ID NAME MODE REPLICAS IMAGE PORTS
8ahvxamblhmc ci_dind replicated 0/1 docker:stable
fli2u5wszrvp ci_register-runner replicated 0/1 gitlab/gitlab-runner:alpine
zftmedknrwma ci_runner replicated 0/1 gitlab/gitlab-runner:alpine
I'm testing all the steps in docker playground using one manager and three workers. I have tried lots of variation of the compose.yml above. That one is the closest to correct, in my opinion.
Replicas are not running. What should I do ?
