# ionoscloud\_pg\_cluster\_v2

The **DBaaS PostgreSQL v2 Cluster data source** can be used to search for and return an existing DBaaS PostgreSQL v2 Cluster. If a single match is found, it will be returned. If your search results in multiple matches, an error will be returned. When this happens, please refine your search string so that it is specific enough to return only one result.

## Example Usage

### By ID

```hcl
data "ionoscloud_pg_cluster_v2" "example" {
  id       = "cluster_id"
  location = "de/txl"
}
```

### By Name

```hcl
data "ionoscloud_pg_cluster_v2" "example" {
  name     = "cluster_name"
  location = "de/txl"
}
```

## Argument Reference

* `id` - (Optional)\[string] ID of the cluster you want to search for.
* `name` - (Optional)\[string] The name of an existing cluster that you want to search for.
* `location` - (Required)\[string] The region in which to look up the cluster. Available locations: `de/fra`, `de/fra/2`, `de/txl`, `es/vit`, `fr/par`, `gb/bhx`, `gb/lhr`, `us/ewr`, `us/las`, `us/mci`.

Either `id` or `name` must be provided. If none, or both are provided, the datasource will return an error.
