mariadb-advanced

MariaDB is an open source, community-developed SQL database server that is widely in use around the world due to its enterprise features, flexibility, and collaboration with leading tech firms. The MariaDB Advanced Helm chart automates deployment and configuration of MariaDB in Kubernetes clusters using Minimus images 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 MariaDB on a Kubernetes cluster using the Minimus MariaDB Advanced Helm chart. MariaDB 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 mariadb-advanced

Step 3: Deploy the Helm Chart

Deploy the Minimus Helm chart:

helm install my-mariadb-advanced oci://helm.mini.dev/mariadb-advanced \
  --version 26.1.7 \
  -n mariadb-advanced \
  --wait

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

helm install my-mariadb-advanced oci://helm.mini.dev/mariadb-advanced \
  --version 26.1.7 \
  -f values.yaml \
  -n mariadb-advanced \
  --wait

Step 4: Verify MariaDB Advanced is Running

To check that the pod was successfully created run:

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

You should see output similar to:

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

Step 5: Test Database Connection

Retrieve the MariaDB root password:

export MARIADB_ROOT_PASSWORD=$(kubectl get secret my-mariadb-advanced-mariadb -n mariadb-advanced -o jsonpath='{.data.mariadb-root-password}' | base64 -d)

Forward the MariaDB port to your local machine:

kubectl port-forward svc/my-mariadb-advanced-mariadb 3306:3306 -n mariadb-advanced

In another terminal, connect using mariadb:

mariadb -h localhost -P 3306 -u root -p"$MARIADB_ROOT_PASSWORD" -e "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-mariadb-advanced -n mariadb-advanced
kubectl delete namespace mariadb-advanced
