Community Helm chart for PostgreSQL on Kubernetes — HelmForge

[mberlofa]

Hi! I maintain a community Helm chart for PostgreSQL as part of HelmForge, an MIT-licensed open-source Helm chart repository. The chart uses the official postgres Docker image from this repository.

With Bitnami moving towards a more restrictive model, there's growing demand for Helm charts that use official upstream images instead of custom Bitnami builds. This chart fills that gap.

The chart supports:

• Official postgres image — no custom builds or proprietary layers
• Standalone and streaming replication architectures
• Prometheus metrics via postgres-exporter sidecar with optional ServiceMonitor
• S3-compatible backup — CronJob with pg_dump, uploads to any S3 endpoint
• Custom postgresql.conf and pg_hba.conf via values
• Configurable init scripts for database and role bootstrapping
• CI validated with lint, template, helm-unittest, and kubeconform

This is a community chart, not affiliated with the PostgreSQL project.

Install:

helm repo add helmforge https://repo.helmforge.dev
helm install postgresql helmforge/postgresql

# Or via OCI
helm install postgresql oci://ghcr.io/helmforgedev/helm/postgresql
