postgresql-advanced

PostgreSQL (Postgres) is an open source object-relational database known for reliability and data integrity. ACID-compliant, it supports foreign keys, joins, views, triggers and stored procedures. The PostgreSQL Advanced Helm chart automates deployment and configuration of PostgreSQL in Kubernetes clusters using the Minimus PostgreSQL Advanced image with hardened security and production-grade configuration.

Prerequisites

A subscription to the Minimus images included in the chart
A running Kubernetes cluster (v1.21 or higher is recommended)
kubectl installed and configured
Helm v3.8 or higher for OCI support (Installation instructions)
Cluster Admin privileges
Persistent storage available in your cluster

Try It Out

In this example we will deploy PostgreSQL on a Kubernetes cluster using the Minimus PostgreSQL Advanced Helm chart. PostgreSQL will be configured with hardened security settings and production-grade defaults.

Step 1: Start Cluster

If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions

Step 2: Create Namespace

Create a namespace:

kubectl create ns postgresql-advanced

Step 3 (optional): Save Values File Locally

If you want to override the chart's defaults, go to the Values tab, save a copy locally, and edit it. Skip this step to deploy with the chart's defaults.

Step 4: Deploy the Helm Chart

Deploy the Minimus Helm chart:

helm install my-postgresql-advanced oci://helm.mini.dev/postgresql-advanced \
  --version 18.6.10 \
  -n postgresql-advanced \
  --wait

If you customized values in Step 3, append -f values.yaml to layer your overrides on top of the chart's defaults:

helm install my-postgresql-advanced oci://helm.mini.dev/postgresql-advanced \
  --version 18.6.10 \
  -f values.yaml \
  -n postgresql-advanced \
  --wait

Step 5: Verify PostgreSQL Advanced is Running

To check that the pod was successfully created run:

kubectl get pods -n postgresql-advanced -l app.kubernetes.io/name=postgresql

You should see output similar to:

NAME                               READY   STATUS    RESTARTS   AGE
my-postgresql-advanced-0           1/1     Running   0          2m

Step 6: Test Database Connection

Retrieve the PostgreSQL password:

export POSTGRES_PASSWORD=$(kubectl get secret my-postgresql-advanced -n postgresql-advanced -o jsonpath='{.data.postgres-password}' | base64 -d)

Forward the PostgreSQL port to your local machine:

kubectl port-forward svc/my-postgresql-advanced 5432:5432 -n postgresql-advanced

In another terminal, connect using psql:

PGPASSWORD=$POSTGRES_PASSWORD psql -h localhost -p 5432 -U postgres -c "SELECT 1;"

You should see a result confirming the connection is working.

Step 7: Clean Up

Uninstall the chart and delete the namespace to remove all resources:

helm uninstall my-postgresql-advanced -n postgresql-advanced
kubectl delete namespace postgresql-advanced
