I have a Centrifugo image that exposes port 8000 for HTTP APIs and port 10000 for gRPC APIs. I have configured Centrifugo with Traefik, and it works fine for HTTP APIs. However, I don't know how to configure it for gRPC.
My configuration for the Traefik service is
version: '3.3'
services:
traefik:
# Use the latest v3.0.x Traefik image available
image: traefik:v3.0
ports:
# Listen on port 80, default for HTTP, necessary to redirect to HTTPS
- 80:80
# Listen on port 443, default for HTTPS
- 443:443
# Listen on port 10000, for grpc
- 10000:10000
deploy:
placement:
constraints:
# Make the traefik service run only on the node with this label
# as the node with it has the volume for the certificates
- node.labels.traefik-public.traefik-public-certificates == true
labels:
# Enable Traefik for this service, to make it available in the public network
- traefik.enable=true
# Use the traefik-public network (declared below)
- traefik.docker.network=traefik-public
# Use the custom label "traefik.constraint-label=traefik-public"
# This public Traefik will only use services with this label
# That way you can add other internal Traefik instances per stack if needed
- traefik.constraint-label=traefik-public
# admin-auth middleware with HTTP Basic auth
# Using the environment variables USERNAME and HASHED_PASSWORD
- traefik.http.middlewares.admin-auth.basicauth.users=${USERNAME?Variable not set}:${HASHED_PASSWORD?Variable not set}
# https-redirect middleware to redirect HTTP to HTTPS
# It can be re-used by other stacks in other Docker Compose files
- traefik.http.middlewares.https-redirect.redirectscheme.scheme=https
- traefik.http.middlewares.https-redirect.redirectscheme.permanent=true
# traefik-http set up only to use the middleware to redirect to https
# Uses the environment variable DOMAIN

- traefik.http.routers.traefik-public-https.middlewares=admin-auth
# Define the port inside of the Docker service to use
- traefik.http.services.traefik-public.loadbalancer.server.port=8080
volumes:
# Add Docker as a mounted volume, so that Traefik can read the labels of other services
- /var/run/docker.sock:/var/run/docker.sock:ro
# Mount the volume to store the certificates
- traefik-public-certificates:/certificates
command:
# Enable Docker in Traefik, so that it reads labels from Docker services
- --providers.docker
# Add a constraint to only use services with the label "traefik.constraint-label=traefik-public"
- --providers.docker.constraints=Label(`traefik.constraint-label`, `traefik-public`)
# Do not expose all Docker services, only the ones explicitly exposed
- --providers.docker.exposedbydefault=false
# Enable Docker Swarm mode
- --providers.swarm.endpoint=unix:///var/run/docker.sock
# Create an entrypoint "http" listening on port 80
- --entrypoints.http.address=:80
# Create an entrypoint "https" listening on port 443
- --entrypoints.https.address=:443
# create an entrypoint "grpc" listening on port 10000
- --entrypoints.grpc.address=:10000
# Create the certificate resolver "le" for Let's Encrypt, uses the environment variable EMAIL
- --certificatesresolvers.le.acme.email=${EMAIL?Variable not set}
# Store the Let's Encrypt certificates in the mounted volume
- --certificatesresolvers.le.acme.storage=/certificates/acme.json
# Use the TLS Challenge for Let's Encrypt
- --certificatesresolvers.le.acme.tlschallenge=true
# Enable the access log, with HTTP requests
- --accesslog
# Enable the Traefik log, for configurations and errors
- --log
# Enable the Dashboard and API
- --api
networks:
# Use the public network created to be shared between Traefik and
# any other service that needs to be publicly available with HTTPS
- traefik-public
volumes:
# Create a volume to store the certificates, there is a constraint to make sure
# Traefik is always deployed to the same Docker node with the same volume containing
# the HTTPS certificates
traefik-public-certificates:
networks:
# Use the previously created public network "traefik-public", shared with other
# services that need to be publicly available via this Traefik

My configuration for the centrifugo service is
centrifugo-service:
image: centrifugo/centrifugo:v5
container_name: centrifugo-service
ports:
- 8000:8000
- 20000:10000
volumes:
- centrifugo_data:/centrifugo
command: centrifugo -c config.json
ulimits:
nofile:
soft: 65535
hard: 65535
networks:
- "traefik-public"
deploy:
replicas: 1
labels:
- traefik.enable=true
- traefik.docker.network=traefik-public
- traefik.constraint-label=traefik-public
- traefik.http.routers.centrifugo_service_http.rule=Host(`my.domain.com`)
- traefik.http.routers.centrifugo_service_http.entrypoints=http
- traefik.http.routers.centrifugo_service_http.middlewares=https-redirect
- traefik.http.routers.centrifugo_service_https.rule=Host(`my.domain.com`)
- traefik.http.routers.centrifugo_service_https.entrypoints=https
- traefik.http.routers.centrifugo_service_https.tls=true
- traefik.http.routers.centrifugo_service_https.tls.certresolver=le
- traefik.http.services.centrifugo_service.loadbalancer.server.port=8000
I tried to change the Traefik configuration for the Centrifugo service, but it is not working for me
labels:
- traefik.enable=true
- traefik.docker.network=traefik-public
- traefik.constraint-label=traefik-public
- traefik.http.routers.centrifugo_service_http.rule=Host(`my.domain.com`)
- traefik.http.routers.centrifugo_service_http.entrypoints=http
- traefik.http.routers.centrifugo_service_http.middlewares=https-redirect
- traefik.http.routers.centrifugo_service_https.rule=Host(`my.domain.com`)
- traefik.http.routers.centrifugo_service_https.entrypoints=https
- traefik.http.routers.centrifugo_service_https.tls=true
- traefik.http.routers.centrifugo_service_https.tls.certresolver=le
- traefik.http.services.centrifugo_service.loadbalancer.server.port=8000
...
- traefik.http.routers.centrifugo_service_grpc.rule=Host(`my.domain.com`)
- traefik.http.routers.centrifugo_service_grpc.entrypoints=grpc
- traefik.http.services.centrifugo_service_grpc.loadbalancer.server.port=10000
Any thoughts on how to map two exposed ports?
Note : I'm new to traefik
