Traefik dashboard only on the http port - docker

Question

I am trying to expose my docker services (like Heimdall, Plex, Tautulli, etc) on my host machines IP for internal purposes only, so without a domain name. I want each service to be accessible ith its own prefix like 192.168.0.100/heimdall, 192.168.0.100/tautulli, etc.
I would like to have the dashboard on a separate port, like 8080, but even after I specify an entry point for 8080 as traefik and set traefik as the entry point for the service it still goes to the port 80 named http.
Is there any issue with my config or is it an issue on traefik side?
docker-compose.yml
version: '3'
services:
traefik:
image: traefik
container_name: traefik
ports:
- "80:80"
- "8080:8080"
restart: always
volumes:
- ./traefik:/etc/traefik
- "/var/run/docker.sock:/var/run/docker.sock:ro"
traefik.yml
entryPoints:
http:
address: ":80"
traefik:
address: ":8080"
api: {}
log:
level: "DEBUG"
providers:
file:
directory: /etc/traefik/dynamic
docker:
endpoint: unix:///var/run/docker.sock
exposedByDefault: false
dashboard.yml
http:
routers:
api:
rule: PathPrefix(`/api`) || PathPrefix(`/dashboard`)
entrypoints:
- traefik
service: api#internal

Answer 1

According to documentation (https://docs.traefik.io/v2.2/operations/api/#insecure), this could help:
api:
insecure: true
It should implicitly use special entrypoint traefik with port 8080.
You can also check this for more info about dashboard: https://docs.traefik.io/operations/dashboard/
EDIT
I have just tried it and it works on port 8080 with this configuration:
docker-compose.yml
version: '3'
services:
traefik:
image: traefik
container_name: traefik
restart: always
ports:
- "80:80"
- "8080:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
- "./dockerfiles/traefik/traefik.yml:/etc/traefik/traefik.yml:ro"
labels:
- "traefik.enable=true"
- "traefik.http.routers.dashboard.rule=PathPrefix(`/api`) || PathPrefix(`/dashboard`)"
- "traefik.http.routers.dashboard.entrypoints=traefik"
- "traefik.http.routers.dashboard.service=api#internal"
traefik.yml (I have used yours without file provider):
entryPoints:
http:
address: ":80"
traefik:
address: ":8080"
api: {}
log:
level: "DEBUG"
providers:
docker:
endpoint: unix:///var/run/docker.sock
exposedByDefault: false
