Welcome!

What version of the Traefik's Helm Chart are you using?

39.0.5

What version of Traefik are you using?

v3.6.10

What did you expect to happen ?

I wanted to roll out traefik on my Kubernetes cluster with ArgoCD

What did you notice instead ?

Error

Cause

The Problem is that the trafik templates uses this Syntax to generate their names:

traefik-helm-chart/traefik/templates/ingressroute.yaml

Line 12 in 8991840

name: {{ $.Release.Name }}-{{ $name }}

The Problem accures when referencing these two lines in the values

traefik-helm-chart/traefik/values.yaml

Line 295 in 8991840

kubernetesCRD:

traefik-helm-chart/traefik/values.yaml

Line 314 in 8991840

kubernetesIngress:

(I'm sure there are more, but I only have these two troublemaker enabled)

It simply copies the name with uppercase letters wich don't match with the lowercase RFC 1123 syntax rules.

My Kubernetes-Client-Version is v1.34.1

What are your values ?

ingressRoute.kubernetesCRD.enabled = true
ingressRoute.kubernetesIngress = true

Additional Information

[mloiseleur]

It seems there is a confusion between providers and IngressRoute here.
Nonetheless, it's true that the chart can be improved by either cleaning wrong input (like for chart name) or failing more gracefully (like in requirements.yaml).
