Multiple domains with Traefik - traefik

Question

I am new to Traefik but trying to migrate from jwilder/nginx-proxy and letsencrypt-companion to Traefik.
I have setup Traefik with this config file:
traefik.yml
entryPoints:
web:
address: :80
http:
redirections:
entryPoint:
to: websecure
scheme: https
websecure:
address: :443
api:
dashboard: true
insecure: true
certificatesResolvers:
le:
acme:
email: username#gmail.com
storage: acme.json
httpChallenge:
# used during the challenge
entryPoint: web
providers:
docker:
endpoint: unix:///var/run/docker.sock
exposedByDefault: false
docker-compose.yml
version: '3'
services:
traefik:
image: traefik:v2.2
restart: always
ports:
- 80:80
- 443:443
- 8080:8080
networks:
- web
volumes:
- /var/run/docker.sock:/var/run/docker.sock
- /data/disk1/traefik/traefik.yml:/traefik.yml
- /data/disk1/traefik/acme.json:/acme.json
container_name: traefik
When starting one container on domain #1
docker-compose.yml
version: "3"
services:
confluence:
container_name: confluence
image: atlassian/confluence-server:7.6.2
volumes:
- /data/disk1/atlassian/application-data/confluence:/var/atlassian/application-data/confluence
ports:
- "8090:8090"
external_links:
- postgres:postgres
environment:
- CATALINA_CONNECTOR_PROXYNAME=confluence.tld
- CATALINA_CONNECTOR_PROXYPORT=443
- CATALINA_CONNECTOR_SCHEME=https
- CATALINA_CONNECTOR_SECURE=true
- VIRTUAL_HOST=confluence.tld
- VIRTUAL_NETWORK=web
- VIRTUAL_PORT=8090
- LETSENCRYPT_EMAIL=user#tld
- LETSENCRYPT_HOST=confluence.tld
labels:
- traefik.enable=true
- traefik.http.routers.confluence.rule=Host(`confluence.tld`)
- traefik.http.routers.confluence.tls=true
- traefik.http.routers.confluence.tls.certresolver=le
- traefik.http.routers.confluence.service=confluence
- traefik.http.services.confluence.loadbalancer.server.port=8090
networks:
- web
restart: always
networks:
web:
external:
name: web
It works perfect.
NOTE: I have kept the environment variables for jwilder/nginx-proxy for the time being
When launching another container with different tld I can't get that working.
E.g.
docker-compose.yml
version: "3"
services:
confluence:
container_name: myapp
image: nginx:latest
volumes:
- /data/disk1/myapp/www/:/usr/share/nginx/html:ro
- /data/disk1/myapp/conf/nginx.conf:/etc/nginx/nginx.conf:ro
ports:
- "9999:80"
environment:
- VIRTUAL_HOST=www.tld2,tld2
- VIRTUAL_NETWORK=web
- VIRTUAL_PORT=9999
- LETSENCRYPT_EMAIL=user#tld2
- LETSENCRYPT_HOST=www.tld2,tld2
labels:
- traefik.enable=true
- traefik.http.routers.myapp.rule=Host(`tld2`) || Host(`www.tld2`)
- traefik.http.routers.myapp.tls=true
- traefik.http.routers.myapp.tls.certresolver=le
- traefik.http.routers.myapp.service=tld2
- traefik.http.services.myapp.loadbalancer.server.port=9999
networks:
- web
restart: always
networks:
web:
external:
name: web
It doesn't work but everything looks OK in Traefik dashboard.
Any ideas?

Answer 1

There is an error in the second docker-compose.yml:
You define the router named mypp to use a service named tld2:
traefik.http.routers.myapp.service=tld2
but your service is named myapp:
traefik.http.services.myapp.loadbalancer.server.port=9999
This should have generated an error in Traefik's log regarding an unresolvable service.
To fix this, configure your router myapp to use the service myapp:
traefik.http.routers.myapp.service=myapp
