how to create helm chart of postgres with pvc

Question

I would like to create a helm chart for PostgreSQL with PVC (persistent volume claim).

I\'ve looked at trying katacoda https://www.katacoda.com/courses/kubernetes/helm-pa

Answer 1

I deployed using following PVC ,values.yaml and Chart.yaml

pvc.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: postgres-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 25Gi

values.yaml

postgresql:
  cpu: 1000m
  memory: 1Gi
  persistence:
    enabled: true
    existingClaim: postgres-pvc
  volumePermissions:
    enabled: true
  replication:
    enabled: false
  initdbScripts:
    psql.sql: |
      CREATE USER user WITH PASSWORD 'pass';
      ALTER USER user WITH SUPERUSER;

Chart.yaml

apiVersion: v2
name: pgname
description: A Short description

type: application

version: 0.1.3

appVersion: 1.16.2

dependencies:
  - name: postgresql
    version: 7.x.x
    repository: https://kubernetes-charts.storage.googleapis.com/
    condition: postgresql.enabled
    tags:
      - services
      - db
      - write

I have got above files in following directory structure.

.
├── Chart.yaml
├── charts
│   └── postgresql-7.7.3.tgz
└── values.yaml

At . I do helm dependency update and helm install release_name . to install. Before that kubectl apply -f pvc.yaml
