# google\_container\_engine\_versions

Provides access to available Google Kubernetes Engine versions in a zone or region for a given project.

-> If you are using the `google_container_engine_versions` datasource with a
regional cluster, ensure that you have provided a region as the `location` to
the datasource. A region can have a different set of supported versions than
its component zones, and not all zones in a region are guaranteed to
support the same version.

## Example Usage

```hcl
data "google_container_engine_versions" "central1b" {
  location           = "us-central1-b"
  version_prefix = "1.12."
}

resource "google_container_cluster" "foo" {
  name               = "terraform-test-cluster"
  location               = "us-central1-b"
  node_version       = "${data.google_container_engine_versions.central1b.latest_node_version}"
  initial_node_count = 1

  master_auth {
    username = "mr.yoda"
    password = "adoy.rm"
  }
}
```

## Argument Reference

The following arguments are supported:

* `location` (Optional) - The location (region or zone) to list versions for.
Must exactly match the location the cluster will be deployed in, or listed
versions may not be available. If `location`, `region`, and `zone` are not
specified, the provider-level zone must be set and is used instead.

* `zone` (Optional, Deprecated) - Zone to list available cluster versions for.
Should match the zone the cluster will be deployed in. `zone` has been
deprecated in favour of `location`.

* `region` (Optional, Deprecated) - Region to list available cluster versions
for. Should match the region the cluster will be deployed in. `region` has been
deprecated in favour of `location`.

* `project` (Optional) - ID of the project to list available cluster versions for. Should match the project the cluster will be deployed to.
  Defaults to the project that the provider is authenticated with.

* `version_prefix` (Optional) - If provided, Terraform will only return versions
that match the string prefix. For example, `1.11.` will match all `1.11` series
releases. Since this is just a string match, it's recommended that you append a
`.` after minor versions to ensure that prefixes such as `1.1` don't match
versions like `1.12.5-gke.10` accidentally. See [the docs on versioning schema](https://cloud.google.com/kubernetes-engine/versioning-and-upgrades#versioning_scheme)
for full details on how version strings are formatted.

## Attributes Reference

The following attributes are exported:

* `valid_master_versions` - A list of versions available in the given zone for use with master instances.
* `valid_node_versions` - A list of versions available in the given zone for use with node instances.
* `latest_master_version` - The latest version available in the given zone for use with master instances.
* `latest_node_version` - The latest version available in the given zone for use with node instances.
* `default_cluster_version` - Version of Kubernetes the service deploys by default.
