After some more time I found my answer.
The service I wanted to deploy was a slightly different version of a service we already have. Stack file for the "original" service:
version: '3.7'
services:
my-service:
image: my-repo:port/company/my-service
ports:
- 81:81
networks:
- my-network
deploy:
replicas: 1
restart_policy:
...

You just have to use the hostname on your docker compose file like this:
hostname: whatever-{{.Node.Hostname}}
Note that you have to prepend something to the hostname to avoid hostnames duplicates.

There is stages in gitlab ci and on 'docker build' stage I don't need ALL env variables. Usually its only a REACT_APP_SERVER_URI variable.
Later I use env file in compose.yml like you are.
env_file:
- ./envs/common.env

I ended up using {{.ManagerStatus.Addr}} and stripping the port number from the results with sed.
for NODE in $(docker node ls -f 'role=manager' --format '{{.Hostname}}'); do
docker node inspect --format '{{.ManagerStatus.Addr}}' ${NODE} | sed 's/:2377//'
done
