Greetings!

I am currently trying to deploy Loki SSD on a local Kubernetes cluster following the SSD guide [[Install the simple scalable Helm chart | Grafana Loki documentation](https://grafana.com/docs/loki/latest/setup/install/helm/install-scalable/)]  
Currently having it point to minio with nfs for testing, but will use on-prem S3 for production.

My issue is from the loki-gateway pod crashing with the below error:

```auto
/docker-entrypoint.sh: No files found in /docker-entrypoint.d/, skipping configuration
2024/06/24 13:25:01 [emerg] 1#1: host not found in resolver "kube-dns.kube-system.svc.cluster.local." in /etc/nginx/nginx.conf:33
nginx: [emerg] host not found in resolver "kube-dns.kube-system.svc.cluster.local." in /etc/nginx/nginx.conf:33

```

I have searched through many previous issues and their resolutions, basically suggesting that kube-dns should be coredns, or adding the clusterdomain and dnsnamespace parameters; although my Kubernetes instance has the coredns service name as kube-dns.

Our requirements is that we need to have Loki in Kubernetes externally accessible through our companies network, as we are purely on-prem with strict policies (banking).

We already have a monolithic Loki deployment on a VM for testing, and planning to integrate this SSD Loki deployment with our existing grafana-server (VM) and be able to push logs from promtail to Loki in Kubernetes.

Please let me know if I am missing anything, any help would be highly appreciated.

Here is my values.yaml file:

```auto
loki:
  schemaConfig:
    configs:
      - from: 2024-04-01
        store: tsdb

This has been fixed by adding the below to the helm chart:

```yaml
global:
  dnsNamespace: kube-system
  clusterDomain: cluster.local
  dnsService: rke2-coredns-rke2-coredns

```

I’m seeing the same error. How did you determine what to put for those values?

Here’s an example of how to determine that: [loki-simple-scalable loki-gateway Nginx startup failed · Issue #7287 · grafana/loki · GitHub](https://github.com/grafana/loki/issues/7287#issuecomment-1282339134)
