How to override ingress rules helm-chart template - kubernetes

Question

Here is my ingress.yml file
spec:
rules:
- host: {{- if .Values.ingress.host }} {{ tpl .Values.ingress.host . }} {{- end }}
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: ssl-redirect
port:
name: use-annotation
{{- range $port := .Values.container.app.port }}
- path: {{ tpl $port.path $ }}
pathType: Prefix
backend:
service:
name: {{ $.Release.Name }}
port:
number: {{ int $port.port }}
{{- end }}
{{ end }}
I want to override this rules some service here is what I try to do in my values.yml file
ingress:
scheme: internal
host: test.com
paths:
- path: /
pathType: Prefix
backend:
service:
name: ssl-redirect
port:
name: use-annotation
- path: /
pathType: Prefix
backend:
service:
name: test
port:
number: 3000
but after I deploy it's not override at all may be in wrong format not sure
UPDATE
I try to this way but It still didn't override rules in ingress
hosts:
- host: test.com
paths:
- path: /test
pathType: Prefix
backend:
service:
name: ssl-redirect
port:
name: use-annotation
- path: /test
pathType: Prefix
backend:
service:
name: test-dev
port:
number: 3000

Answer 1

ingress.yaml should be something like
kind: Ingress
metadata:
name: {{ $name }}
labels:
app.kubernetes.io/instance: {{ .Release.Name }}
app.kubernetes.io/managed-by: {{ .Release.Service }}
{{- with $_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: {{ $name }}
servicePort: 80
{{- end }}
{{- end }}
{{- end }}
values.yaml
ingress:
enabled: false
annotations: {}
# kubernetes.io/ingress.class: nginx
# kubernetes.io/tls-acme: "true"
hosts:
- host: test.example.io
paths: [/path]
# tls: []
# - secretName: chart-example-tls
# hosts:
# - chart-example.local
Another example :
Ingress.yaml : https://github.com/helm/charts/blob/master/stable/ghost/templates/ingress.yaml
values.yaml : https://github.com/helm/charts/blob/master/stable/ghost/values.yaml

i'm assuming that this is not the whole ingress.yaml template because if it is, you are missing the apiVersion, kind and metadata block entirely. :)
helm can create a baseline chart with helm create <chartName>. in this baseline chart, there is a ingress.yaml template with a corresponding values.yaml which works just fine and follows helm best practices. i recommend you use that one to ease and speed up your workflow instead of writing your own template, even if you do not understand it at first. the generated templates by helm create are worth studying because there is a lot to learn from them and they are a good showcase of how to solve some common problems when writing helm charts and how to follow best practices for labeling, annotations etc.
anyways, if you want to stick to that data structure and create your own template, this is the template that worked during my tests. i used the helm template command to check if there are any rendering errors whilst providing your values.
