Helm chart volumes and volumeMounts in deployment file - devops

Question

I can't make my chart use my volumes, and volumeMounts values. In my values.yaml file I have something like this:
volumes:
- name: docker1
hostPath:
path: /var/
- name: docker2
hostPath:
path: /usr/
- name: docker3
hostPath:
path: /opt/
volumeMounts:
- name: docker1
mountPath: /var/
- name: docker2
mountPath: /usr/
- name: docker3
mountPath: /opt/
In my _deployment.tpl file I have something like this:
apiVersion: apps/v1
kind: Deployment
metadata:
name: {{ include "fullname" . }}
namespace: {{ .Values.namespace }}
labels:
{{- include "labels" . | nindent 4 }}
spec:
replicas: {{ .Values.replicaCount }}
revisionHistoryLimit: {{ .Values.revisionHistory | default 2 }}
selector:
matchLabels:
{{- include "selectorLabels" . | nindent 6 }}
template:
metadata:
annotations:
{{- toYaml .Values.podAnnotations | nindent 8 }}
labels:
{{- include "labels" . | nindent 8 }}
spec:
imagePullSecrets:
{{- toYaml .Values.imagePullSecrets | nindent 8 }}
containers:
- name: {{ .Chart.Name }}
image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"
imagePullPolicy: {{ .Values.image.pullPolicy }}
ports:
{{- toYaml .Values.image.ports | nindent 10 }}
env:
{{- toYaml .Values.env | nindent 10 }}
volumeMounts:
- name: {{- toYaml .Values.volumeMounts | default "" | nindent 10 }}
volumes:
- name: {{- toYaml .Values.volumes | default "" | nindent 10 }}
nodeSelector:
{{- toYaml .Values.nodeSelector | nindent 8 }}
tolerations:
{{- toYaml .Values.tolerations | nindent 8 }}
{{- end }}
I tried to mount volumes and volumeMounts the same way I do with env variables (they work) but sadly it doesn't work.

There is a problem with the indentation of your code.
Volumes should be at the same indentation level as containers.
As follow:
spec:
imagePullSecrets:
{{- toYaml .Values.imagePullSecrets | nindent 8 }}
containers:
- name: {{ .Chart.Name }}
image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"
imagePullPolicy: {{ .Values.image.pullPolicy }}
ports:
{{- toYaml .Values.image.ports | nindent 12 }}
env:
{{- toYaml .Values.env | nindent 12 }}
volumeMounts:
{{- toYaml .Values.volumeMounts | default "" | nindent 12 }}
volumes:
{{- toYaml .Values.volumes | default "" | nindent 8 }}
nodeSelector:
{{- toYaml .Values.nodeSelector | nindent 8 }}
tolerations:
{{- toYaml .Values.tolerations | nindent 8 }}
If you want to debug the template, you can refer to the official helm document operation.
