no matches for kind "StatefulSet" in version "apps/v1beta1" on strapdata/elassandra chart #9
Description
Hi,
today i tried to install strapdata/elassandra chart on a kubernetes v 1.18 cluster.
Setup failed with error "no matches for kind "StatefulSet" in version "apps/v1beta1".
I dug into templates/statefulset.yaml to change apiVersion to v1 like suggested in similar issues with statefulsets and i faced a new error:
"Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(StatefulSet.spec): missing required field "selector" in io.k8s.api.apps.v1.StatefulSetSpec"
I added a selector object in spec duplicating the metadata labels and i receveid a new error:
Error: StatefulSet.apps "elassandra" is invalid: spec.template.metadata.labels: Invalid value: map[string]string{"app":"elassandra", "release":"elassandra"}: selector does not match template labels
So I changed selector labels copying spec.template.metadata.labels section and the chart deployed correctly (or at least it seems to be!)
The resulting yaml looks like this:
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: {{ template "elassandra.fullname" . }}
labels:
app: {{ template "elassandra.name" . }}
chart: {{ template "elassandra.chart" . }}
release: {{ .Release.Name }}
heritage: {{ .Release.Service }}
spec:
selector:
matchLabels:
app: {{ template "elassandra.name" . }}
release: {{ .Release.Name }}
serviceName: {{ template "elassandra.fullname" . }}
replicas: {{ .Values.config.cluster_size }}
podManagementPolicy: {{ .Values.podManagementPolicy }}
updateStrategy:
type: RollingUpdate
template:
metadata:
labels:
app: {{ template "elassandra.name" . }}
release: {{ .Release.Name }}
...
I attach the full modified templates/statefulset.yaml
