Traefik v2.5.3

What’s new in Traefik v2.5.3?

by | 01.10.2021 | Changelog

Traefik came with a new version of 2.5.3. This version mainly focuses on bug fixing and adding documents. This article will cover all of those entirely. It is not a big update, so this article will be short and crisp.

Buckle up for a ride. Let’s start!

What is Traefik?

Traefik, which we can pronounce as traffic, is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with our existing infrastructure components such as Docker, Swarm mode, Kubernetes, Marathon, Consul, Etcd, Rancher, Amazon ECS, etc. and helps in configuring itself automatically and dynamically. Pointing Traefik at an orchestrator should be the only configuration step we will need.


The latest release brings a few updates in the documentation. We will take a look at all of those. We can see the doc that tells the fixing of TCP middleware whitelist example for middleware and file. Also, we see the addition of a doc that shows the default proxy headers list in middleware. Finally, we can see the documentation which iterates the fixing of golang doc URLs.

Bug Fixes

Bug fixes got some preference in this update. Though it is few, it will help the users have a better experience with Traefik. For consulcatalog, we can see the fixing of certChan defaulting on the consul catalogue provider. We see a couple of bug fixes with k8s/crd and k8s. Firstly, we can see the fixing of the peerCertURI config for the k8s crd provider.

We can now see the working of disableHTTP2 with k8s crd. Again, we see the fixing of the ServersTransport reference from the IngressRoute service definition. We also see the addition of cross namespace verification in Kubernetes CRD. In the case of metrics, version 2.5.3 brings the fixing of metrics of Prometheus router’s. For Plugins, we see the updating of yaegi to v0.10.0.


Although it is short, we can see how the latest release of version 2.5.3 brings the addition of a few documentations along with the fixing of a few bugs. It will help users have a better understanding of the product along with a better user experience. Try out the new Traefik by clicking here. Contribute to this fantastic project by clicking here.
