# What is RadonDB MySQL
**RadonDB MySQL** is an open-source, cloud-native, and high-availability cluster solution based on MySQL. It adopts the architecture of one leader node and multiple replicas, with management capabilities for security, automatic backups, monitoring and alerting, automatic scaling, and so on.
**RadonDB MySQL Kubernetes** supports installation, deployment and management of RadonDB MySQL clusters on [Kubernetes](https://kubernetes.io/), [KubeSphere](https://kubesphere.com.cn/) and [Rancher](https://rancher.com), and automates tasks involved in running RadonDB MySQL clusters.
## Features
🧠 **High-availability MySQL**: Automatic decentralized leader election, failover within seconds, and strong data consistency in cluster switching
✏️ **Cluster management**
💻 **Monitoring and alerting**
✍️ [**S3 backups**](docs/en-us/backup_and_restoration_s3.md) and [**NFS backups**](docs/en-us/backup_and_restoration_nfs.md)
🎈 **Log management**
👨 **Account management**
🎨 [**Others**](docs/en-us/)
## Architecture
1. Automatic decentralized leader election by the Raft protocol
2. Synchronizing data by Semi-Sync replication based on GTID mode
3. Supporting high-availability through [Xenon](https://github.com/radondb/xenon.git)
## Roadmap
| Version | Features | Mode |
|------|--------|------|
| 3.0 | Automatic O&M

# 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.
```plain
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](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/) named `demo-mysql-operator`.
```plain
helm install demo radondb/mysql-operator
```
> **Notice**
> This step also creates the [CRD](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/) 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](https://github.com/radondb/radondb-mysql-kubernetes/blob/main/docs/zh-cn/config_para.md).
```plain
kubectl apply -f https://github.com/radondb/radondb-mysql-kubernetes/releases/latest/download/mysql_v1alpha1_mysqlcluster.yaml
```
