🐛 Bug Description

I'm configuring my k3s setup with mycluster.k8s.somedomain.net as my cluster-domain.

This means servicename.somenamespace.svc.cluster.local does not resolve, but servicename.somenamespace.svc.mycluster.k8s.somedomain.net and servicename.somenamespace.svc do.

In a minimal deployment from Helm chart, I manually edited the resulting Deployments and removed cluster.local in NEXT_PUBLIC_BACKEND_URL and POSTGRES_DATABASE_URL. This complicates pushes, and would require hacks upon an automated push such as via ArgoCD.

Ideally either the helmcharts would expose the clusterdomain in values yaml, or they'd omit it and depend on search-domains being set up correctly in CoreDNS (as I did above).

I did not yet get to a functioning system, and I'll postpone it for later, so I don't know if this assumption about cluster-domain propagated anywhere else, but a quick search revealed at least one yaml file in tools dir to mention cluster.local.

🔄 Steps To Reproduce

apiVersion: helm.cattle.io/v1
kind: HelmChart
metadata:
  namespace: kagent
  name: kagent-crds
spec:
  targetNamespace: kagent
  createNamespace: true
  version: "0.9.0"  # https://github.com/kagent-dev/kagent/pkgs/container/kagent%2Fhelm%2Fkagent-crds
  repo: ghcr.io/kagent-dev
  chart: kagent/helm/kagent-crds
  valuesContent: |
    # n/a

  createNamespace: true
  version: "0.9.0"  # https://github.com/kagent-dev/kagent/pkgs/container/kagent%2Fhelm%2Fkagent

    providers:

      openAI:
        apiKey: 12345
      # gemini, anthropic, azureOpenAI

    controller:
      env: {}
      # envFrom: [ { secretRef: { name: controller-secrets } } ]

    ipv6:
      enabled: true

Note, this is actually processed by ArgoCD appset, but applying on k3s with kubectl apply -f should have a comparable result. As noted, k3s has been initialized with a custom cluster-domain.
