On redeploy traefik deletes route

[atlekbai]

Hello!
When running docker stack deploy ... the second time, traefik deletes its route to url.
For example, I deployed first-time nginx server on host example.com, after redeploy, example.com shows 404 page.

How to fix this issue?

my yaml file:

version: '3.3'

volumes:
    web_data: {}

networks:
  net:
    driver: overlay
    attachable: true
  traefik-public:
    external: true

services:
  web:
    image: *****
    networks:
      - net
      - default
      - traefik-public
    environment:
      - DB_TYPE=mysql
      - DB_HOST=mysql
      - DB_DATABASE=****
      - DB_USERNAME=***
      - DB_PASSWORD=****
    volumes:
      - web_data:/var/www/html/storage/app
    deploy:
      mode: replicated
      replicas: 3
      labels:
        - traefik.frontend.rule=Host:example.com
        - traefik.enable=true
        - traefik.tags=${TRAEFIK_PUBLIC_TAG:-traefik-public}
        - traefik.docker.network=traefik-public
        # Traefik service that listens to HTTP
        - traefik.redirectorservice.frontend.entryPoints=http
        - traefik.redirectorservice.frontend.redirect.entryPoint=https
        # Traefik service that listens to HTTPS
        - traefik.webservice.frontend.entryPoints=https

Maybe you have forgotten to export the enviroment variables?

No, the same yaml file. When I try to redeploy it, its host will show 404

Yeah same file but are the enviroment variables still present when you "echo" them. So try to

EXPORT=...

again to maybe solve the problem :-)

I solved the problem deploying with flag --with-registry-auth.
