Traefik. Proxy to another backend - docker

Question

If I please contact domain.com/api/v0/add, I get the expected result, but if I speak at domain.com/ipfs, then get 404.
How to proxy all calls starting with the way /ipfs ??
I briefly studied the documentation traefik, but never found an answer.
I have docker-compose.yml file:
version: '3.4'
volumes:
traefik: {}
services:
ipfs0:
container_name: ipfs0
image: ipfs/go-ipfs:release
ports:
- "4001:4001"
- "5001:5001"
- "8080:8080"
volumes:
- ./compose/ipfs0:/data/ipfs
ipfs1:
container_name: ipfs1
image: ipfs/go-ipfs:release
ports:
- "4101:4001" # ipfs swarm
- "5101:5001" # expose if needed/wanted
- "8180:8080" # exposes if needed/wanted
volumes:
- ./compose/ipfs1:/data/ipfs
traefik:
build:
context: .
dockerfile: ./compose/traefik/Dockerfile
depends_on:
- ipfs0
volumes:
- traefik:/etc/traefik/acme
ports:
- "0.0.0.0:80:80"
- "0.0.0.0:443:443"
and traefik.toml file
