Questa pagina descrive come modificare un'istanza AlloyDB per PostgreSQL esistente.
Dopo aver creato un'istanza, puoi modificarla mentre è in esecuzione per cambiarne le
impostazioni. Per informazioni su come le impostazioni e le modifiche delle istanze possono influire su un'istanza, vedi
Visualizzare le impostazioni dei cluster e delle istanze.
Nella colonna Nome risorsa, fai clic su un cluster.
Nella pagina Panoramica, vai alla sezione Istanze nel cluster e individua l'istanza che vuoi modificare. Nel
menu Azioni istanza, fai clic su Modifica.
Aggiorna le impostazioni modificabili per l'istanza e fai clic su
Aggiorna istanza.

For information about how instance settings and edits can impact an\ninstance, see\n[View cluster and instance settings](/alloydb/docs/cluster-settings?resource=primary).\n\n\nBefore you begin\n----------------\n\n- The Google Cloud project you are using must have been [enabled to access AlloyDB](/alloydb/docs/project-enable-access).\n- You must have one of these IAM roles in the Google Cloud project you are using:\n - `roles/alloydb.admin` (the AlloyDB Admin predefined IAM role)\n - `roles/owner` (the Owner basic IAM role)\n - `roles/editor` (the Editor basic IAM role)\n\n If you don't have any of these roles, contact your Organization Administrator to request\n access.\n\n\u003cbr /\u003e\n\nProcedure\n---------\n\nMost edits can be applied to an instance only when it's running. \n\n### Console\n\n1. In the Google Cloud console, go to the **Clusters** page.\n\n\n [Go to Clusters](https://console.cloud.google.com/alloydb/clusters)\n2. In the **Resource Name** column, click a cluster.\n3. On the **Overview** page, go to the **Instances in your cluster** section and find the instance that you want to edit. In the **Instance actions menu** , click **Edit**.\n4. Update any editable settings for your instance and click **Update Instance**.\n\n### gcloud\n\nTo use the gcloud CLI, you can\n[install and initialize](/sdk/docs/install) the Google Cloud CLI, or you\ncan use [Cloud Shell](/shell/docs/using-cloud-shell).\n\nTo edit an instance, use the\n[`instances update`](/sdk/gcloud/reference/alloydb/instances/update)\ncommand along with the configuration that you want to update, as shown in the\nfollowing example: \n\n```\ngcloud instances update INSTANCE_ID \\\n --region=REGION_ID \\\n --cluster=CLUSTER_ID \\\n```\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: The ID of the instance.\n- \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: The region where the instance is placed.\n- \u003cvar translate=\"no\"\u003eCLUSTER_ID\u003c/var\u003e: The ID of the cluster where the instance is placed.\n\nThe following example command shows how to update the number of nodes in the\nread pool: \n\n```\ngcloud alloydb instances update my-read-instance \\\n --cluster=my-cluster \\\n --region=us-central1 \\\n --read-pool-node-count=3\n```\n\nTo learn more about instance configuration flags, see\n[gcloud alloydb instances update](/sdk/gcloud/reference/alloydb/instances/update)."]]
