Deleting a cluster

This page explains how to delete a Game Servers cluster.

Before you begin

Before you start, we recommend you familiarize yourself with key concepts in the Game Servers Overview. Make sure you have also performed the following tasks:

Ensure that you have enabled the Game Services API.

Enable Game Services API

Either choose a shell with Cloud SDK installed, or use an API client:

Cloud Shell

To launch Cloud Shell, perform the following steps:

Go to Google Cloud Console.

Google Cloud Console
From the upper-right corner of the console, click the Activate Cloud Shell button:

A Cloud Shell session opens inside a frame lower on the console. You use this shell to run gcloud commands.

Local shell

To install gcloud, install the Cloud SDK, which includes the gcloud command-line tool.

Verify that you have set desired default project for gcloud command-line tool (otherwise you need to specify flag --project explicitly for each command later):

gcloud config list project

If not you can run the following command to set a default project, replacing project-id with your desired project ID :

gcloud config set project project-id

Run the following command to verify your version of the Google Cloud SDK. Game Servers requires version 306.0.0 or higher of the SDK.

gcloud version

To update your installation, run the following command:

gcloud components update

Client Library

Google Cloud Game Servers can be controlled programmatically using a client library. See Client Libraries Overview for instructions on using the library and authenticating.

Deleting a cluster

Deleting a Game Servers cluster doesn't delete any resources in the cluster.

Console

In the Cloud Console, go to the Realms & Clusters page.

Go to Game Servers
Expand a realm to see the game server clusters that belong to it.
In the last table column for the cluster, click the ellipses and select Remove game server cluster.

gcloud

You can delete a Game Servers global or regional cluster using the gcloud command-line tool.

To delete a global cluster:

Run the following command and replace the placeholder values, such as clusterID and realmID, with appropriate values:
```
gcloud game servers clusters delete clusterID --realm=realmID --dry-run
```
The output returns the targetState so that you can preview the operation before deleting the cluster.

To delete the cluster, run the following command:

gcloud game servers clusters delete clusterID --realm=realmID --no-dry-run

To delete a regional cluster:

Run the following command and replace the placeholder values, such as clusterID, with appropriate values:
```
gcloud game servers clusters delete clusterID --realm=realmID --location=region --dry-run
```
The output returns the targetState so that you can preview the operation before deleting the cluster.

To delete the cluster, run the following command:

gcloud game servers clusters delete clusterID --realm=realmID --location=region --no-dry-run

The variable placeholders correspond to the following descriptions:

clusterID is the unique identifier that you specified for this cluster.
realmID is the unique identifier that you specified for the parent realm of this cluster.
region is the region for the cluster, if applicable. Pick the same location as the parent realm.

def delete_cluster(project_id, location, realm_id, cluster_id):
    """Deletes a game server cluster."""

    client = gaming.GameServerClustersServiceClient()

    request = game_server_clusters.DeleteGameServerClusterRequest(

Verifying that your cluster has been deleted

Verify that you successfully deleted the cluster by listing your global or regional clusters using the gcloud command-line tool.

To list all clusters, run the following command:

gcloud game servers clusters list

To list clusters in a region, run the following command and replace region with the region that you want to list the clusters in:

gcloud game servers clusters list --location=region

To list all clusters in a realm, run the following command and replace realmID with the parent realm and region with the region of the cluster, if applicable:

gcloud game servers clusters list --realm=realmID --location=region

Your deleted cluster no longer appears in the output of the command.
