Deploy MariaDB in Kubernetes

This provides an example of how to use Helm to install a quick-start MariaDB database to a Kubernetes cluster. For detailed information on MariaDB installation and configuration options, refer to documentation for Bitnami package for MariaDB.

Before you begin

Before you begin, you need a functioning Kubernetes cluster with the tools Helm and kubectl installed. For details, see the Prerequisites section.

Step 1 - Prepare passwords

Create a Kubernetes secret with your desired database passwords:

BASH

kubectl create secret generic mariadb-passwords \
    --from-literal=mariadb-root-password='foo123' \
    --from-literal=mariadb-password='foo123'

Step 2 - Install MariaDB

Install MariaDB using Helm with a custom database name and username. This example uses the nameejbca:

BASH

helm install mariadb \
    --set auth.database=ejbca \
    --set auth.username=ejbca \
    --set auth.existingSecret=mariadb-passwords \
    oci://registry-1.docker.io/bitnamicharts/mariadb

Step 3 - Wait for the installation to finish

Use the following command to monitor the pod creation process:

BASH

kubectl get pods -w -l app.kubernetes.io/instance=mariadb

You can start using the database as soon as all pods are ready (1/1).
