Traefik Integrations
Here are some stack decisions, common use cases and reviews by companies and developers who chose Traefik in their tech stack.
We are looking to configure a load balancer with some admin UI. We are currently struggling to decide between NGINX, Traefik, HAProxy, and Envoy. We will use a load balancer in a containerized environment and the load balancer should flexible and easy to reload without changes in case containers are scaled up.
We use Traefik as the web server.
The reasons for choosing Traefik over Nginx are as follows:
- Traefik built-in Let’s Encrypt and supports automatic renewal
- Traefik automatically enables HTTP/2
- Prometheus can be supported through simple Traefik configuration
- cookiecutter django integrates Traefik's configuration by default
We switched to Traefik so we can use the REST API to dynamically configure subdomains and have the ability to redirect between multiple servers.
We still use nginx with a docker-compose to expose the traffic from our APIs and TCP microservices, but for managing routing to the internet Traefik does a much better job
The biggest win for naologic was the ability to set dynamic configurations without having to restart the server
