# ionoscloud\_mariadb\_cluster\_v2

The `ionoscloud_mariadb_cluster_v2` data source can be used to retrieve information about an existing MariaDB V2 cluster.

## Example Usage

### By id

```hcl
data "ionoscloud_mariadb_cluster_v2" "by_id" {
  id       = "example-id"
  location = "de/txl"
}
```

### By name

```hcl
data "ionoscloud_mariadb_cluster_v2" "by_name" {
  name     = "my-mariadb-cluster"
  location = "de/txl"
}
```
