Use LocalXpose with Traefik
This tutorial will go through using LocalXpose to access Traefik from the internet and therefore accessing multiple local services using one tunnel.
Traefik is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components (Docker, Swarm mode, Kubernetes, Marathon, Consul, Etcd, Rancher, Amazon ECS, ...) and configures itself automatically and dynamically.

In front of these three services we will run Traefik which will mange the routing between these services and lastly will create LocalXpose container to access Traefik from the internet.
We will use a custom wildcard domain, for this example we will use this custom domain
example.com, so we need to reserve it:loclx domain reserve --domain '*.example.com'
Then we should add a CNAME record in our DNS provider, You can read more about domain reservations here.
Change the following
*.example.com with your actual reserved domain and replace the access token with yours.version: "3.8"
services:
# LocalXpose service will expose traefik container to the internet
localxpose:
image: localxpose/localxpose:latest # read more here https://hub.docker.com/r/localxpose/localxpose
# forward any incoming requests to traefik container
command: tunnel -r http --reserved-domain "*.example.com" --to traefik:80
environment:
# Get your access token from your dashboard here https://localxpose.io/dashboard/access
ACCESS_TOKEN: YOURS_HERE
# Traefik service which will handle the routing between the other
# docker services
traefik:
image: traefik:v2.8
command:
# Enabling docker provider
- "--providers.docker=true"
# Do not expose containers unless explicitly told so
- "--providers.docker.exposedbydefault=false"
# Traefik will listen to incoming request on the port 80 (HTTP)
- "--entrypoints.web.address=:80"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
# Nginx service is a demo application
nginx:
image: nginxdemos/hello:0.3
labels:
# Explicitly tell Traefik to expose this container
- "traefik.enable=true"
# The domain the service will respond to
- "traefik.http.routers.nginx.rule=Host(`nginx.example.com`)"
# Allow request only from the predefined entry point named "web"
- "traefik.http.routers.nginx.entrypoints=web"
# Tell Traefik to use the port 80 to connect to `nginx` container
- "traefik.http.services.nginx.loadbalancer.server.port=80"
# Nextcloud is our file hosting service
nextcloud:
image: nextcloud:stable-apache
labels:
# Explicitly tell Traefik to expose this container
- "traefik.enable=true"
# The domain the service will respond to
- "traefik.http.routers.nextcloud.rule=Host(`nextcloud.example.com`)"
# Allow request only from the predefined entry point named "web"
- "traefik.http.routers.nextcloud.entrypoints=web"
# Tell Traefik to use the port 80 to connect to `nextcloud` container
- "traefik.http.services.nextcloud.loadbalancer.server.port=80"
# Ghost is our blogging platform
ghost:
image: ghost:5.5.0
environment:
url: http://blog.example.com
labels:
# Explicitly tell Traefik to expose this container
- "traefik.enable=true"
# The domain the service will respond to
- "traefik.http.routers.ghost.rule=Host(`blog.example.com`)"
# Allow request only from the predefined entry point named "web"
- "traefik.http.routers.ghost.entrypoints=web"
# Tell Traefik to use the port 2368 to connect to `ghost` container
- "traefik.http.services.ghost.loadbalancer.server.port=2368"
docker-compose up
Now you can access these services from the internet like
https://nginx.example.com, https://blog.example.com and https://nextcloud.example.com.
