mkozioro opened a new issue #39:
URL: https://github.com/apache/pulsar-helm-chart/issues/39
**Describe the bug**
I've noticed, that multiple zookeeper pods started on same kubernetes node.
It looks like issue with labels and podAntiAffinity settings.
Example using zookeeper
koziorow@pl1lxl-108450:~/projects/LNS-DevEnv/repo/batch-service-infra/terraform-apache-pulsar$
kubectl describe pod pulsar-zookeeper-0
Name: pulsar-zookeeper-0
Namespace: default
Priority: 0
Node: aks-default-12797261-vmss000001/10.240.0.115
Start Time: Mon, 13 Jul 2020 12:22:02 +0200
Labels: **app=pulsar**
cluster=pulsar
component=zookeeper
controller-revision-hash=pulsar-zookeeper-7d87bf67f9
release=pulsar
statefulset.kubernetes.io/pod-name=pulsar-zookeeper-0
In chart:
podAntiAffinity:
requiredDuringSchedulingIgnoredDuringExecution:
- labelSelector:
matchExpressions:
- key: "app"
operator: In
values:
**- "{{ template "pulsar.name" . }}-{{
.Values.zookeeper.component }}"**
- key: "release"
operator: In
values:
- {{ .Release.Name }}
- key: "component"
operator: In
values:
- {{ .Values.zookeeper.component }}
topologyKey: "kubernetes.io/hostname"
**Expected behavior**
Zookeeper pods should start on different nodes. Problem exists also in other
components.
