Unable to see services with traefik - docker-compose

Question

I'm a beginner and Im a bit confused about how traefik works...
I want to use the app freqtrade (trading bot) as a docker service and replicate it with different type of configuration, if you have 5min you can go check this guy I want to do the same thing...
But I don't understant why I can't see my app running with traefik :
What I did :
Configure my domain to my server like that :
server config
And on this machine I create a docker swarm and the treafik service with this tutorial and then, my docker compose file look like that :
```
version: '3.3'
services:
traefik:
# Use the latest v2.2.x Traefik image available
image: traefik:v2.2
ports:
# Listen on port 80, default for HTTP, necessary to redirect to HTTPS
- 80:80
# Listen on port 443, default for HTTPS
- 443:443
networks:
- traefik-public
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-http.rule=Host(`${DOMAIN?Variable not set}`)
- traefik.http.routers.traefik-public-http.entrypoints=http
- traefik.http.routers.traefik-public-http.middlewares=https-redirect
# traefik-https the actual router using HTTPS
# Uses the environment variable DOMAIN
- traefik.http.routers.traefik-public-https.rule=Host(`${DOMAIN?Variable not set}`)
- traefik.http.routers.traefik-public-https.entrypoints=https
- traefik.http.routers.traefik-public-https.tls=true
# Use the special Traefik service api#internal with the web UI/Dashboard
- traefik.http.routers.traefik-public-https.service=api#internal
# Use the "le" (Let's Encrypt) resolver created below
- traefik.http.routers.traefik-public-https.tls.certresolver=le
# Enable HTTP Basic auth, using the middleware created above
- 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.docker.swarmmode
# 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 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
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:
traefik-public:
driver: overlay
attachable: true
```
And deploy it :
docker stack deploy -c traefik.yml traefik
After that traefik works fine. Why I can't see the port 8080 in my entrypoint ? is it important for others services ?
Entrypoint traefik
I try to disable the firewall in configuration of the server and also do ufw allow 8080 but nothing change...
I create my a application like I create traefik service with this docker-compose file :
---
version: '3'
networks:
traefik_traefik-public:
external: true
services:
freqtrade:
image: freqtradeorg/freqtrade:stable
# image: freqtradeorg/freqtrade:develop
# Use plotting image
# image: freqtradeorg/freqtrade:develop_plot
# Build step - only needed when additional dependencies are needed
# build:
# context: .
# dockerfile: "./docker/Dockerfile.custom"
restart: unless-stopped
container_name: freqtrade
volumes:
- "./user_data:/freqtrade/user_data"
# Expose api on port 8080 (localhost only)
# Please read the https://www.freqtrade.io/en/stable/rest-api/ documentation
# before enabling this.
networks:
- traefik_traefik-public
deploy:
mode: replicated
replicas: 1
placement:
constraints:
- node.role == manager
restart_policy:
condition: on-failure
delay: 5s
command: >
trade
--logfile /freqtrade/user_data/logs/freqtrade.log
--db-url sqlite:////freqtrade/user_data/tradesv3.sqlite
--config /freqtrade/user_data/config.json
--strategy SampleStrategy
labels:
- traefik.http.routers.bot001.tls=true'
- traefik.http.routers.bot001.rule=Host(`bot001.bots.lordgoliath.com`)'
- traefik.http.services.bot001.loadbalancer.server.port=8080'
and this is a part of the configuation file of the bot (to access to the UI)
"api_server": {
"enabled": true,
"enable_openapi": true,
"listen_ip_address": "0.0.0.0",
"listen_port": 8080,
"verbosity": "info",
"jwt_secret_key": "somethingrandom",
"CORS_origins": ["https://bots.lordgoliath.com"],
"username": "api",
"password": "api"
},
then :
docker stack deploy -c docker-compose.yml freqtrade
So I have that :
goliath#localhost:~/freqtrade_test/user_data$ docker service ls
ID NAME MODE REPLICAS IMAGE PORTS
nkvpjjztjibg freqtrade_freqtrade replicated 1/1 freqtradeorg/freqtrade:stable
6qryu28ute9i traefik_traefik replicated 1/1 traefik:v2.2 *:80->80/tcp, *:443->443/tcp
I see the bot running with the command docker service logs freqtrade_freqtrade but
when I try to go on my domain to see it have only the Traefik dashboard and can't see anything else running.
traefik http
traefik https
how I can see my app freqtrade running ? how can I access to the bot UI via my domain ?
Thanks !
Sorry for my bad English I hope this is clear enough to understand my problem

This is the minimal config you need to integrate in order to see the traefik dashboard on localhost:8080
version: "3.9"
services:
traefik:
image: traefik:latest
command: |
--api.insecure=true
ports:
- 8080:8080
Then, your minimal configuration to get traefik to route example.com to itself:
version: "3.9"
networks:
public:
attachable: true
name: traefik
services:
traefik:
image: traefik:latest
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
command: |
--api.insecure=true
--providers.docker.exposedbydefault=false
--providers.docker.swarmmode
--providers.docker.network=traefik
ports:
- 80:80
networks:
- public
deploy:
labels:
traefik.enable: "true"
traefik.http.routers.traefik.rule: Host(`example.com`)
traefik.http.services.traefik.loadbalancer.server.port: 8080
Now, minimal https support - using Traefik self signed certs to start with. Note that we configure tls on the https entrypoint, which means traefik implicitly creates http and https variants for each router.
version: "3.9"
networks:
public:
attachable: true
name: traefik
services:
traefik:
image: traefik:latest
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
command: |
--api.insecure=true
--providers.docker.exposedbydefault=false
--providers.docker.swarmmode
--providers.docker.network=traefik
--entrypoints.http.address=:80
--entrypoints.https.address=:443
--entrypoints.https.http.tls=true
deploy:
placement:
constraints:
- node.role == manager
ports:
# - 8080:8080
- 80:80
- 443:443
networks:
- public
deploy:
labels:
traefik.enable: "true"
traefik.http.routers.traefik.rule: Host(`example.com`)
traefik.http.services.traefik.loadbalancer.server.port: 8080
At this point, gluing in your le config should be simple.
Your freqtrade stack compose would need to be this. If this is a single node swarm, just omit the placement constraints, but when the swarm is large enough to have workers, then tasks that don't need to be on managers should explicitly be kept on workers.
Traefik needs to talk to the swarm api over the docker socket, which is on manager nodes only, which is why it must be node.role==manager.
version: "3.9"
