Session Persistence using Traefik on Docker Swarm Replicas

I trying to implement sticky session on dockers-swarm with traefik, but I could not achieve session persistence over two replicas on same machine.
In my docker-compose.yml, I have added labels for traefik and added the loadbalancer as well. Below is my docker-compose.yml, (Although the indentation might not look proper here, but it correct in actual project)
version: '3'
services:
web:
image: php:7.2.11-apache-stretch
ports:
- "8080:80"
volumes:
- ./code/:/var/www/html/hello/
stdin_open: true
tty: true
deploy:
mode: replicated
replicas: 2
restart_policy:
condition: any
update_config:
delay: 2s
labels:
- "traefik.docker.network=docker-test_privnet"
- "traefik.port=80"
- "traefik.backend.loadbalancer.sticky=true"
- "traefik.frontend.rule=PathPrefix:/hello"
networks:
- privnet
loadbalancer:
image: traefik
command:
--docker
--docker.swarmmode
--docker.watch
--web
--loglevel=DEBUG
ports:
- 80:80
- 9090:8080
volumes:
- /var/run/docker.sock:/var/run/docker.sock
deploy:
restart_policy:
condition: any
mode: replicated
replicas: 1
update_config:
delay: 2s
placement:
constraints: [node.role == manager]
networks:
- privnet
networks:
privnet:
external: true
Am I missing anything?

A few things.
.stickyis deprecated in favor oftraefik.backend.loadbalancer.stickiness=true- I don't think you need to set the network with
traefik.docker.networkwhen you only have a single network connected to that service. - Make sure you're testing with a tool that uses cookies, which is how sticky sessions stay sticky. If using curl, be sure to use
-cand-bas in this example. - I used the voting app sample from my test Swarm setup and added sticky sessions to the "vote" service and it worked for me on a single node. If using a multi-node swarm you'll need the LB in front of multiple swarm nodes to also enable sticky.

Hi, Seems like we need to set traefik.docker.network if we need to have the traefik dashboard in a subdomain like traefik.domain.com. Then, the issue was solved after I fixed my front end rules and defined Host rule for each service.
