August 27th, 2024 10:40 AM Mr. Q Categories: Docker
Traefik is a powerful and flexible reverse proxy that makes it easy to manage and route traffic to various services in a Docker environment. Whether you’re hosting services locally or managing external resources, Traefik’s dynamic configuration capabilities allow you to effortlessly connect and secure your services. In this guide, we’ll walk through the process of adding an external service to your Traefik setup, demonstrating how to route traffic to a service running on a remote server and make it accessible through a custom domain. By the end of this tutorial, you’ll have a robust and secure connection to your external service, all managed seamlessly by Traefik.
1. Update dynamic.yml
You need to add a new service and router for the external service in your dynamic.yml
file.
Copy001http:
002
003 middlewares:
004 # Existing middlewares here...
005
006 # Other middlewares...
007
008 services:
009 external-service:
010 loadBalancer:
011 servers:
012 - url: "http://xx.xx.xx.xx:8080"
013 passHostHeader: true
014
015 routers:
016 # Existing routers here...
017
018 external-router:
019 rule: Host(`example.com`)
020 entryPoints:
021 - websecure
022 middlewares:
023 - TBA-headers
024 - TBA-whitelist
025 - TBA-compress
026 service: external-service
027 tls:
028 certResolver: lets-encrypt
029
2. Update traefik.yml
Ensure that the file
provider is properly configured to watch for changes in the dynamic.yml
file. No changes are needed here if it’s configured correctly, but make sure that:
- The
filename
in thefile
provider points todynamic.yml
. - The
watch
option is set totrue
.
Copy001providers:
002 file:
003 filename: dynamic.yml
004 watch: true
3. Verify and Restart
After updating & validating the files:
- Check the Configuration: Make sure there are no syntax errors or issues in the YAML files.
- Restart Traefik: Apply the changes by restarting the Traefik service.
You can restart Traefik with the following Docker command:
Copy001docker-compose restart traefik
This setup will ensure that requests to ai.qbytesworld.com
will be routed to 92.68.10.58:8080
through Traefik, with proper TLS configuration and middleware handling.
