Hi all, We want to assign storageClass to pinot zookeeper in the helm chart so that whenever a pinot-zookeeper pod gets created it automatically claims a PV. But I see, there is no direct way to assign using values.yaml We tried installing incubator/zookeeper using the below command

helm -n my-pinot-kube install pinot-zookeeper incubator/zookeeper --set replicaCount=1

and disabled the zookeeper in helm/pinot/values.yaml by modifying zookeeper.enabled to false. But we see face an error from

_helpers.tpl

indicating not able to fetch the

zookeeper.url

and related to

configurationOverride

.

Error: template: pinot/templates/server/statefulset.yml:63:27: executing "pinot/templates/server/statefulset.yml" at <include "zookeeper.url" .>: error calling include: template: pinot/templates/_helpers.tpl:79:33: executing "zookeeper.url" at <index .Values "configurationOverrides" "zookeeper.connect">: error calling index: index of nil pointer

Any help is appreciated !

You can find it under zookeeper helmChart 😛 in short, here are the options under

zookeeper

section in

values.yaml

file:

persistence:
  enabled: true
  ## zookeeper data Persistent Volume Storage Class
  ## If defined, storageClassName: <storageClass>
  ## If set to "-", storageClassName: "", which disables dynamic provisioning
  ## If undefined (the default) or set to null, no storageClassName spec is
  ##   set, choosing the default provisioner.  (gp2 on AWS, standard on
  ##   GKE, AWS & OpenStack)
  ##
  # storageClass: "-"
  accessMode: ReadWriteOnce
  size: 5Gi

Thank you @Xiang Fu for the help! I tried mentioning just the below values in values.yaml for zookeeper section

zookeeper:
    enabled: false
    url: <ip>
    port: <pod-exposed-port>

When I install pinot using

helm -n my-pinot-kube install pinot .

it throws error:

Error: template: pinot/templates/server/statefulset.yml:63:27: executing "pinot/templates/server/statefulset.yml" at <include "zookeeper.url" .>: error calling include: template: pinot/templates/_helpers.tpl:79:33: executing "zookeeper.url" at <index .Values "configurationOverrides" "zookeeper.connect">: error calling index: index of nil pointer

Line 79 in _helpers.tpl is

{{- $zookeeperConnectOverride := index .Values "configurationOverrides" "zookeeper.connect" }}

isee

I tried :

zookeeper:
    enabled: false
    url: <ip>
    port: <pod-exposed-port>
    connect: 192.168.49.2:30760
    zookeeper.connect: 192.168.49.2:30760

Still

Error: template: pinot/templates/server/statefulset.yml:63:27: executing "pinot/templates/server/statefulset.yml" at <include "zookeeper.url" .>: error calling include: template: pinot/templates/_helpers.tpl:79:33: executing "zookeeper.url" at <index .Values "configurationOverrides" "zookeeper.connect">: error calling index: index of nil pointer

Does it have issue with index .Values "configurationOverrides" ?

I feel so, let’s remove that line in _helpers.tpl
