I know this is some kind of syntax/yaml structure related error but the message is so cryptic I have no idea what the issue is:
Error: render error in "mychart/templates/ingress.yaml": template: mychart/templates/ingress.yaml:35:37: executing "mychart/templates/ingress.yaml" at <.Values.network.appP...>: can't evaluate field Values in type interface {}
This is in my values.yaml:
network:
appPort: 4141
This is the ingress.yaml:
{{- $fullName := include "mychart.fullname" . -}}
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: {{ $fullName }}
labels:
app.kubernetes.io/name: {{ include "mychart.name" . }}
helm.sh/chart: {{ include "mychart.chart" . }}
app.kubernetes.io/instance: {{ .Release.Name }}
app.kubernetes.io/managed-by: {{ .Release.Service }}
{{- with .Values.ingress.annotations }}
annotations:
{{- toYaml . | nindent 4 }}
{{- end }}
spec:
{{- if .Values.ingress.tls }}
tls:
{{- range .Values.ingress.tls }}
- hosts:
{{- range .hosts }}
- {{ . | quote }}
{{- end }}
secretName: {{ .secretName }}
{{- end }}
{{- end }}
rules:
{{- range .Values.ingress.hosts }}
- host: {{ .host | quote }}
http:
paths:
{{- range .paths }}
- path: {{ . }}
backend:
serviceName: {{ $fullName }}
servicePort: {{ .Values.network.appPort }}
{{- end }}
{{- end }}
Why doesn't {{ .Values.network.appPort }}
work? I have used values with this same structure in other places
Isn't it just scope issue?
Try something as below
{{- $fullName := include "mychart.fullname" . -}}
{{- $networkAppPort := .Values.network.appPort -}}
...
.... omitted code
...
http:
paths:
{{- range .paths }}
- path: {{ . }}
backend:
serviceName: {{ $fullName }}
servicePort: {{ $networkAppPort }}
{{- end }}
{{- end }}
