postgresql-advanced-fips

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 FIPS Helm chart automates deployment and configuration of PostgreSQL in Kubernetes clusters using Minimus images with FIPS-compliant, 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 FIPS Helm chart. PostgreSQL will be configured with FIPS-validated cryptographic modules, 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-fips

Step 3: Deploy the Helm Chart

Deploy the Minimus Helm chart:

helm install my-postgresql-advanced-fips oci://helm.mini.dev/postgresql-advanced-fips \
  --version 0.1.0 \
  -n postgresql-advanced-fips \
  --wait

If you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes, and deploy with -f values.yaml:

helm install my-postgresql-advanced-fips oci://helm.mini.dev/postgresql-advanced-fips \
  --version 0.1.0 \
  -f values.yaml \
  -n postgresql-advanced-fips \
  --wait

Step 4: Verify PostgreSQL Advanced FIPS is Running

To check that the pod was successfully created run:

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

You should see output similar to:

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

Step 5: Test Database Connection

Retrieve the PostgreSQL password:

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

Forward the PostgreSQL port to your local machine:

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

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 6: Clean Up

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

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