cluster.local appears in domain name

[rlevytskyi]

Hello Team,

After installing DevLake I receive 502 error.

Inspecting the UI pod logs, I see records like this:

2025/09/18 07:50:32 [error] 23#23: *87 devlake-lake.ep-devlake.svc.cluster.local could not be resolved (3: Host not found)...

Inspecting the pod, I see proper records at the resolv.conf:

search ep-devlake.svc.k8s-msq-sbx svc.k8s-msq-sbx k8s-msq-sbx exadel.by
nameserver 169.254.25.10
options ndots:5

After manual edit of the devlake-ui deployment replacing 'cluster.local' with proper 'k8s-msq-sbx' it starts working properly.

I've checked the helm chart and it seems to be hardcoded to me:
% grep -r cluster.local charts/devlake/templates/deployments.yaml: value: {{ include "devlake.fullname" . }}-lake.{{ .Release.Namespace }}.svc.cluster.local:8080 charts/devlake/templates/deployments.yaml: value: {{ .Release.Name }}-grafana.{{ .Release.Namespace }}.svc.cluster.local:80

Could you please tell if it's possible use the proper domain?

I had the same problem here.

I would recommend to add a "clusterName" field in the values.yaml to let this to configured.

In the mean time, overwritting this value using an additional env variable in the commonEnvs would work as it is loaded after this hardcoded value. On the other hand, this unnecessary environment variable would get defined in the other container which are not using it, so not that lovely.

e.g. values.yaml

clusterName: "<<your k8s cluster domain name>>"

#the common environments for all pods except grafana, grafana needs to be set in grafana section seperately
commonEnvs:
  TZ: "UTC"
  DEVLAKE_ENDPOINT: '{{ include "devlake.fullname" . }}-lake.{{ .Release.Namespace }}.svc.{{ .Values.clusterName }}:{{ .Values.lake.port }}'

The clusterName value can be also defined using a --set parameter during the helm chart call such as the extra environment variable if you are not loading an external values.yaml file to overwrite the default values.

Hi, Thanks for the information.
Would you like to submit a PR to fix the issue?
