Traefik perpetually out of sync in Argo CD due to missing divisor spec for GOMEMLIMIT and GOMAXPROCS

Welcome!

• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

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

28.0.0

What version of Traefik are you using?

traefik:v3.0.0

What did you do?

I setup Traefik on ArgoCD and I am constantly seeing a diff:

What did you see instead?

Based on this comment on a similar problem (different application) cilium/cilium#30634
I was able to correct it using this comment: cilium/cilium#30635 (comment)

Specifically I added:

    resource.customizations.ignoreDifferences.apps_Deployment: |
      jqPathExpressions:
      - '.spec.template.spec.containers[] | select(.name == "traefik").env[] | select(.name == "GOMAXPROCS" or .name == "GOMEMLIMIT").valueFrom.resourceFieldRef.divisor'

to my ArgoCD cm

The fix for this looks straight forward:
https://github.com/cilium/cilium/pull/30635/files

A default value for divisor needs to be added

What is your environment & configuration?

Kubernetes 1.29.3 - used as a Deployment

Additional Information

No response

Adding divisor: 1 AFTER

traefik-helm-chart/traefik/templates/_podtemplate.tpl

Line 725 in 54ec665

resource: limits.cpu

And

traefik-helm-chart/traefik/templates/_podtemplate.tpl

Line 731 in 54ec665

resource: limits.memory

Should fix this pretty quickly
