For ArgoCD configuration I would like to pass vault secrets into ConfigMap.
My config map template:
{{- if .Values.server.configEnabled }}
apiVersion: v1
kind: ConfigMap
metadata:
name: argocd-cm
labels:
{{- include "argo-cd.labels" (dict "context" . "component" .Values.server.name "name" "cm") | nindent 4 }}
{{- if .Values.server.configAnnotations }}
annotations:
{{- range $key, $value := .Values.server.configAnnotations }}
{{ $key }}: {{ $value | quote }}
{{- end }}
{{- end }}
data: {{- include "argo-cd.config" $ | nindent 4 }}
{{- end }}
and values part:
server:
podAnnotations:
vault.hashicorp.com/agent-inject: "true"
vault.hashicorp.com/auth-path: "auth/gke"
vault.hashicorp.com/role: "default-role"
config:
oidc.config: |
name: Google
issuer: https://accounts.google.com
clientID: |
{{- with secret "secret-gke/data/argocd/argocd-server/client" -}}
{{ .Data.data.clientID }}
{{- end -}}
clientSecret: |
{{- with secret "secret-gke/data/argocd/argocd-server/client" -}}
{{ .Data.data.clientSecret }}
{{- end -}}
podAnnotations allow to inject secrets into Pod and configAnnotations do not solve the issue, so how to inject secrets into ConfigMap?

I am new to helm and kubernetes, so I maybe missed something.
I have created a Helm Chart to deploy MISP. Unfortunately, I am now getting the following error.
Error: INSTALLATION FAILED: template: misp/templates/serviceaccount.yaml:4:11: executing "misp/templates/serviceaccount.yaml" at <include "misp.fullname" .>: error calling include: template: misp/templates/_helpers.tpl:7:40: executing "misp.fullname" at <.Values.misp.name>: nil pointer evaluating interface {}.name
My helpers.tpl looks like this:
{{/*

Thank you for your help
try to regenerate the files
I have simple helm chart. I have a labels: block that I need to refer in a Deployment
Here's my values.yaml
labels:
app: test-app
group: test-group
provider: test-provider
And in the templates/deployment.yaml I need to add the above whole labels block. So I did;
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: {{ include "accountmasterdata.fullname" . }}
namespace: {{ .Values.namespace }}
labels:
{{ .Values.labels | nindent 4 }}
{{- include "accountmasterdata.labels" . | nindent 4 }}
But I get the following error
wrong type for value; expected string; got map[string]interface {}
Can someone help me with two things:
How can I solve this issue
And in the line where it says {{- include "accountmasterdata.labels" . | nindent 4 }} , where I can see the accountmasterdata.labels values? And how to override those?
Thank you!
Iterating over a mapping is covered in the "Variables" documentation:
For data structures that have both a key and a value, we can use range to get both. For example, we can loop through .Values.favorite like this:
apiVersion: v1
kind: ConfigMap
metadata:
name: {{ .Release.Name }}-configmap
data:
myvalue: "Hello World"
{{- range $key, $val := .Values.favorite }}
{{ $key }}: {{ $val | quote }}
{{- end }}
So in your template, you would handle the value of .Values.labels like this:
labels:
{{- range $name, $value := .Values.labels }}
{{ $name | quote }}: {{ $value | quote }}
{{- end -}}
And in the line where it says {{- include "accountmasterdata.labels" . | nindent 4 }} , where I can see the accountmasterdata.labels values? And how to override those?
Is this a template you are writing? If so, where have you defined these values? Presumably in your templates/ directory there exists a file that includes something like:
{{- define "accountmasterdata.labels" -}}
...
{{- end -}}
The contents of that block are what will get inserted at the point of reference.
Lastly, in your template you have:
namespace: {{ .Values.namespace }}
But you probably want to use .Release.Namespace instead:
namespace: {{ .Release.Namespace | quote }}
With the above changes in place, I end up with:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: {{ include "accountmasterdata.fullname" . }}
namespace: {{ .Release.Namespace | quote }}
labels:
{{- range $name, $value := .Values.labels }}
{{ $name | quote }}: {{ $value | quote }}
{{- end -}}
{{- include "accountmasterdata.labels" . | nindent 4 }}
So I have been trying to fix some charts we inherited and all the others went fine except this 1 which is giving me a headache.
I understand what thew error is telling me
Error: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(Ingress.spec.rules[0].http.paths): invalid type for io.k8s.api.networking.v1.HTTPIngressRuleValue.paths: got "map", expected "array" but I can't find where this map appears in the spec below. I see the paths being in list format.
Does anyone have any idea where exactly the problem is?

EDIT 1
Doing a helm lint . with the same flags that the helm upgrade --install would do, throws no errors
You have:
paths:

...
You're missing the actual path:
paths:
- path: /

I have helm 3 template created using helm create microservice command. it has below files.
/Chart.yaml
./values.yaml

How to I added microservice.labels template?. Do I need to create microservice.labels.tlp file?
Any tips to fix this error.
Thanks

I copied the ingress.yaml file to, chart created older version helm. this value was missing in _helpers.tpl file. Now I copied new version of hellpers.tpl file. deployment works now.
I am using Azure Kubernetes Service to deploy my applications. I deployed application access to it via Ingress. Application must request permissions from another service using https. But in the logs I see this error message
