Devi assicurarti di disporre delle autorizzazioni adeguate nel tuo Google Cloud progetto
per soddisfare i requisiti di installazione per il cluster,
il parco risorse e Cloud Service Mesh:
Se disponi del ruolo Proprietario per il progetto Google Cloud , hai più autorizzazioni del necessario per creare cluster, installare e configurare Knative Serving.
Per scoprire come registrare il cluster e abilitare la federazione delle identità per i carichi di lavoro per GKE nel tuo parco risorse, consulta Registrazione di un cluster. I tipi di cluster supportati al di fuori di Google Cloud vengono registrati per impostazione predefinita.
Cloud Service Mesh richiede che il cluster utilizzi un tipo di macchina con almeno 4 vCPU, ad esempio e2-standard-4. Per informazioni dettagliate sui requisiti, consulta la guida all'installazione di Cloud Service Mesh. Se devi modificare il tipo di macchina del tuo cluster esistente, consulta la sezione Migrazione dei carichi di lavoro in tipi di macchine diversi.
Per usufruire del provisioning automatico dei domini di test, Cloud Service Mesh utilizza un gateway di ingresso e un servizio denominato istio-ingress nel namespace istio-system. Per abilitare la creazione del gateway durante l'installazione della funzionalità, utilizza --option legacy-default-ingressgateway
dello script di installazione asmcli.

[See the documentation and requirements for your cluster](/anthos/clusters/docs).\n - Note that the\n [Cloud Service Mesh permissions requirements](/service-mesh/v1.18/docs/installation-permissions)\n also meet all the permission requirements for installing and configuring\n Knative serving.\n\n - Using other roles and the minimum requirements:\n\n Depending on your organization, you can also meet the permission\n requirements through a combination of the following predefined roles:\n - Google Cloud project permissions: [Basic *Editor* role](/iam/docs/understanding-roles#basic)\n\n - Fleet permissions:\n [*GKE Hub Admin*](/iam/docs/understanding-roles#gke-hub-roles)\n or a role that includes the following permissions:\n\n - `gkehub.features.create`\n - `gkehub.features.update`\n - Cluster permissions:\n [A Kubernetes Engine Admin Role](/iam/docs/understanding-roles#kubernetes-engine-roles):\n\n - *Kubernetes Engine Admin*\n - *Kubernetes Engine Cluster Admin*\n- A cluster with the following configuration is required:\n\n - A supported\n\n [Google Distributed Cloud cluster](/anthos/clusters/docs/on-prem).\n For previous installations on Google Distributed Cloud clusters, you must\n [migrate Knative serving on VMware to a fleet](/kubernetes-engine/enterprise/knative-serving/docs/install/outside-gcp/upgrade-vmware).\n\n **[Preview](/products#product-launch-stages)** : Other GKE clusters\n environments outside Google Cloud are currently available as a \"*Preview* \".\n [Learn more](/kubernetes-engine/enterprise/knative-serving/docs/install/outside-gcp).\n - Registered to a fleet:\n\n [Go to GKE clusters](https://console.cloud.google.com/kubernetes/list/overview)\n | **Tip:** Workload Identity Federation for GKE allows you to authenticate to Google Cloud services and it's also required by Cloud Service Mesh. Enabling fleet Workload Identity Federation in your cluster during fleet registration can reduce the configuration and deployment time.\n\n To learn how to register your cluster and enable Workload Identity Federation for GKE in\n your fleet, see\n [Registering a cluster](/kubernetes-engine/fleet-management/docs/register/gke). Supported cluster types outside Google Cloud are registered by default.\n - In-cluster [Cloud Service Mesh version 1.18 or later is\n installed](/service-mesh/v1.18/docs/unified-install/install-anthos-service-mesh).\n Additionally, note the following prerequisites:\n\n - The [Google-managed Cloud Service Mesh control plane](/service-mesh/docs/supported-features-mcp) is currently not fully supported by Knative serving. Use the in-cluster control plane instead.\n - Cloud Service Mesh requires that your cluster use a machine type with at least 4 vCPUs, such as `e2-standard-4`. See the Cloud Service Mesh installation guide for details about requirements. If you need to change your existing cluster's machine type, see [Migrating workloads to different machine types](/kubernetes-engine/docs/tutorials/migrating-node-pool).\n - In order to benefit from the automated provisioning of test domains - Cloud Service Mesh uses an ingress gateway and a service named `istio-ingress` in namespace `istio-system`. To enable creation of the gateway during the feature installation use `--option legacy-default-ingressgateway` of `asmcli` installation script.\n- [The command-line environment must be set up](/kubernetes-engine/enterprise/knative-serving/docs/install/outside-gcp/command-line-tools).\n\n- The following APIs must be enabled in your Google Cloud project:\n\n - Google Kubernetes Engine API: Build and manage container-based applications.\n - Cloud Build API: Create and manage builds.\n - Container Registry API: Push and pull images in Container Registry.\n\n [Enable the APIs in the Google Cloud console](https://console.cloud.google.com/start/api?id=container.googleapis.com,containerregistry.googleapis.com,cloudbuild.googleapis.com)"]]
