Chart deployment issues about helm-controller

[DarthBlair]

I have the same Problem...

Same problem here with the official longhorn helm repository.

apiVersion: helm.cattle.io/v1
kind: HelmChart
metadata:
  name: longhorn
  namespace: kube-system
spec:
  chart: longhorn/longhorn
  targetNamespace: longhorn-system
  repo: https://charts.longhorn.io
  valuesContent: |-
    defaultSettings:
      createDefaultDiskLabeledNodes: true

+ helm_v3 repo add longhorn https://charts.longhorn.io
Error: looks like "https://charts.longhorn.io" is not a valid chart repository or cannot be reached: Get "https://charts.longhorn.io/index.yaml": dial tcp: lookup charts.longhorn.io on 10.43.0.10:53: server misbehaving

10.43.0.10:53 is your cluster DNS service record IE CoreDNS. This error means that DNS is not working inside your cluster. You should review the CoreDNS pods logs.

Same problem here.
+ helm_v3 repo add stable https://charts.helm.sh/stable/ Error: looks like "https://charts.helm.sh/stable/" is not a valid chart repository or cannot be reached: Get "https://charts.helm.sh/stable/index.yaml": dial tcp: lookup charts.helm.sh on 172.30.0.10:53: server misbehaving

Same answer as above, check on your coredns pod logs.

I had resolved this problem by using nodelocaldns in my cluster. Apparently some DNS queries were timing out but by having DNS cache per node made those queries works perfectly well.
