Docker compose/Swarm: Use network names of compose file - docker

Question

I work with a compose file which looks like this:
version: '3.7'
services:
shinyproxy:
build: /home/shinyproxy
deploy:
#replicas: 3
user: root:root
hostname: shinyproxy
image: shinyproxy-example
networks:
- sp-example-net
volumes:
- type: bind
source: /var/run/docker.sock
target: /var/run/docker.sock
- type: bind
source: /home/shinyproxy/application.yml
target: /opt/shinyproxy/application.yml
....
networks:
sp-example-net:
driver: overlay
attachable: true
This shinyproxy application uses the following .yml file
proxy:
port: 5000
template-path: /opt/shinyproxy/templates/2col
authentication: keycloak
admin-groups: admins
users:
- name: jack
password: password
groups: admins
- name: jeff
password: password
container-backend: docker-swarm
docker:
internal-networking: true
container-network: sp-example-net
specs:
- id: 01_hello
display-name: Hello Application
description: Application which demonstrates the basics of a Shiny app
container-cmd: ["R", "-e", "shinyproxy::run_01_hello()"]
container-image: openanalytics/shinyproxy-demo
container-network: "${proxy.docker.container-network}"
access-groups: test
- id: euler
display-name: Euler's number
container-cmd: ["R", "-e", "shiny::runApp('/root/euler')"]
container-image: euler-docker
container-network: "${proxy.docker.container-network}"
access-groups: test
To deploy the stack I run the following command:
docker stack deploy -c docker-compose.yml test
This results in the following: Creating network test_sp-example-net
So indead of sp-example_net my network´s name is test_sp-example_net
Is there a way to prevent this kind of combination for my network name?
Thank you!
