traefik v2.2 help using only docker-compose router service entrypoint - docker-compose

Question

Started learning about docker, traefik for playing in home.
Aim: Put everything all together in docker-compose.yml and .env files, understand basics, comment accordingly.
Want to get dashboard from traefik.test.local/dashboard rather test.local:8080, similarly api should be accessed from traefik.test.local/api. So that don't have to think about port numbers.
added lines to /etc/hosts
127.0.0.1 test.local
127.0.0.1 traefik.test.local
docker-compose.yml
version: "3.7"
services:
traefik:
# The official v2 Traefik docker image
image: traefik:v2.2
# Lets name the container
container_name: traefik
command:
# Enables the web UI
- "--api.insecure=true"
# Tells Traefik to listen to docker
- "--providers.docker"
ports:
# The HTTP port
- "80:80"
# The Web UI (enabled by --api.insecure=true)
- "8080:8080"
volumes:
# So that Traefik can listen to the Docker events
- /var/run/docker.sock:/var/run/docker.sock
#labels:
#- "traefik.http.routers.router.rule=Host(`traefik.test.local/dashboard`)"
#- "traefik.http.routers.router.rule=Host(`traefik.test.local/api`)"

Not able to understand how to connect from router to services. Also correct me if I am wrong anywhere. Thank you.

Answer 1

you can achieve this using the following definition, you need to add labels for the routers and service and not only the router
proxy:
image: traefik:v2.1
command:
- '--providers.docker=true'
- '--entryPoints.web.address=:80'
- '--entryPoints.metrics.address=:8082'
- '--providers.providersThrottleDuration=2s'
- '--providers.docker.watch=true'
- '--providers.docker.swarmMode=true'
- '--providers.docker.swarmModeRefreshSeconds=15s'
- '--providers.docker.exposedbydefault=false'
- '--providers.docker.defaultRule=Host("traefik.lvh.me")'
- '--accessLog.bufferingSize=0'
- '--api=true'
- '--api.dashboard=true'
- '--api.insecure=true'
- '--ping.entryPoint=web'
volumes:
- '/var/run/docker.sock:/var/run/docker.sock:ro'
ports:
- '80:80'
- '8080:8080'
restart:
always
deploy:
labels:
- traefik.enable=true
- traefik.docker.network=monitoring
- traefik.http.services.traefik-dashboard.loadbalancer.server.port=8080
- traefik.http.routers.traefik-dashboard.rule=Host(`dashboard.traefik.lvh.me`)
- traefik.http.routers.traefik-dashboard.service=traefik-dashboard
- traefik.http.routers.traefik-dashboard.entrypoints=web
- traefik.http.services.traefik-api.loadbalancer.server.port=80
- traefik.http.routers.traefik-api.rule=Host(`api.traefik.lvh.me`)
- traefik.http.routers.traefik-api.service=traefik-api
- traefik.http.routers.traefik-api.entrypoints=web
logging:
driver: json-file
options:
'max-size': '10m'
'max-file': '5'
also if you use lvh.me domain you not need to edit /etc/hosts
