how to proxy to backend in docker compose with traefik - docker

Question

I'm setting up a frontend and backend with traefik and docker compose like so:
version: "3.7"
services:
frontend:
image: frontend:tag
networks:
- traefik-network
labels:
- traefik.enable=true
- traefik.port=80
- traefik.docker.network=traefik-network
- traefik.http.routers.frontend.entrypoints=web
- traefik.http.routers.frontend.rule=PathPrefix(`/`)
backend:
image: backend:tag
networks:
- traefik-network
labels:
- traefik.enable=true
- traefik.port=3000
- traefik.docker.network=traefik-network
reverse-proxy:
image: traefik:v2.0
networks:
- traefik-network
labels:
- traefik.docker.network=traefik-network
- traefik.enable=true
command:
- --log.level=DEBUG
- --api.insecure=true
- --providers.docker=true
- --providers.docker.exposedbydefault=false
- --entryPoints.web.address=:80
- --entryPoints.name.forwardedHeaders.insecure=true
ports:
- "80:80"
- "3000:3000"
- "8080:8080"
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
networks:
traefik-network:
name: traefik-network
previously i used nginx to create proxy from FE to BE like so
upstream go_backend {
server backend:8085 max_fails=3 fail_timeout=50;
}
location /api/ {
proxy_pass http://go_backend/;
}
How am I able to proxy requests from the FE to the BE like this with traefik v2?
No toml file.
What results did you expect:
When i go to localhost, the requests from the server gets forwarded to backend:3000.
What happens now:
When i go to localhost, the requests is not reached to the backend.

For anyone in the same position:
- traefik.docker.network=traefik-network
- traefik.http.routers.backend.entrypoints=backend
Remember to set entrypoints to your service:
- traefik.http.routers.<s-name>.entrypoints=<s-name>
