Quick start

👀 This tutorial demonstrates how to deploy a RadonDB MySQL cluster (Operator) on Kubernetes.

Preparation

📦 Prepare a Kubernetes cluster.

Steps

Step 1: Add a Helm repository.

helm repo add radondb https://radondb.github.io/radondb-mysql-kubernetes/

Step 2: Install Operator.

Set the release name to demo and create a Deployment named demo-mysql-operator.

helm install demo radondb/mysql-operator

Notice

This step also creates the CRD required by the cluster.

Step 3: Deploy a RadonDB MySQL Cluster.

Run the following command to create an instance of the mysqlclusters.mysql.radondb.com CRD and thereby create a RadonDB MySQL cluster by using the default parameters. To customize the cluster parameters, see Configuration Parameters.

kubectl apply -f https://github.com/radondb/radondb-mysql-kubernetes/releases/latest/download/mysql_v1alpha1_mysqlcluster.yaml
