Charmed Traefik

traefik-k8s is a charm for Traefik, an ingress integrator and reverse proxy for Kubernetes. It is an essential part of the COS Lite bundle.

This Charmed Operator handles instantiation, scaling, configuration, and Day 2 operations specific to Traefik.

This operator drives the Traefik application, and it can be composed with other operators to deliver a complex application or service.

The charm offers different kinds of ingress:

  • Ingress per app. This is the typical use case. The related app has only one ingress url like /mymodel-myapp, and Traefik will load-balance in a round-robin fashion across all units.
  • Ingress per unit. Each unit of the related app obtains its own ingress url, like /mymodel-myapp-0.
  • Traefik route. This is a means to provide a fully custom ingress configuration to Traefik.

Ingress is a purely in-model concern. Traefik will happily cross-model relate with your remote ingress requirers, but will be unable to actually route to them. This is a known issue.

This charm is:

  • part of the COS Lite bundle
  • intended to be used together with certificates provider over the tls-certificates interface
