Google Distributed Cloud admite OpenID Connect (OIDC) y el Protocolo ligero de acceso a directorios (LDAP) como mecanismos de autenticación para interactuar con el servidor de la API de Kubernetes de un clúster, mediante GKE Identity Service. GKE Identity Service es un servicio de autenticación que te permite usar las soluciones de identidad existentes para la autenticación múltiple en varios entornos de GKE Enterprise. Los usuarios pueden acceder y usar los clústeres de GKE desde la línea de comandos (todos los proveedores) o desde la consola de Google Cloud (solo OIDC), todo con tu proveedor de identidad existente.
GKE Identity Service funciona con cualquier tipo de clúster de equipo físico: administrador, usuario, híbrido o independiente. Puedes usar proveedores de identidad locales y de acceso público. Si tu empresa ejecuta un servidor de los Servicios de federación de Active Directory (ADFS), este podría funcionar como tu proveedor de OpenID. También puedes usar servicios de proveedores de identidad de acceso público, como Okta. Una Public Certificate Authority (CA) conocida o una CA privada pueden emitir certificados de proveedor de identidad.
Si ya usas o quieres usar ID de Google para acceder a tus clústeres de Anthos en lugar de un proveedor de OIDC o LDAP, te recomendamos usar la puerta de enlace de Connect para la autenticación. Obtén más información en Conéctate a clústeres registrados con la puerta de enlace de Connect.
Antes de comenzar
Ten en cuenta que los sistemas sin interfaz gráfica no son compatibles. Se usa un flujo de autenticación basado en el navegador para solicitar el consentimiento de los usuarios y autorizar su cuenta de usuario.
Para realizar la autenticación a través de la consola de Google Cloud, cada clúster que desees configurar debe estar registrado en tu flota de proyectos.
Proceso y opciones de configuración
GKE Identity Service admite proveedores de identidad mediante los siguientes protocolos:
OpenID Connect (OIDC). Proporcionamos instrucciones específicas para la configuración de algunos proveedores de OpenID populares, incluido Microsoft, pero puedes usar cualquier proveedor que implemente OIDC.
Elige entre las siguientes opciones de configuración del clúster:
Configura tus clústeres a nivel de la flota según las instrucciones de Configura clústeres para GKE Identity Service a nivel de flota (versión preliminar, Google Distributed Cloud versión 1.8 y posteriores). Con esta opción, Google Cloud administra la configuración de autenticación de forma centralizada.
Configurar los clústeres de forma individual mediante las instrucciones en Configura clústeres para GKE Identity Service con OIDC. Debido a que la configuración a nivel de flota es una función de versión preliminar, te recomendamos usar esta opción en entornos de producción, si usas una versión anterior de Google Distributed Cloud o si necesitas funciones de GKE Identity Service que aún no son compatibles con la administración del ciclo de vida a nivel de la flota.
Después de configurar GKE Identity Service, los usuarios pueden acceder a los clústeres configurados mediante la línea de comandos o a consola de Google Cloud.

GKE Identity Service is an authentication service\nthat lets you bring your existing identity solutions for authentication to\nyour clusters. Users can log in to and use clusters from the command line\n(all providers) or from the Google Cloud console (OIDC only), all using your\nexisting identity provider.\n\nGKE Identity Service works with any kind of bare metal cluster: admin, user,\nhybrid, or standalone. You can use both on-premises and publicly reachable\nidentity providers. For example, if your enterprise runs an [Active Directory\nFederation Services\n(ADFS)](https://docs.microsoft.com/en-us/windows-server/identity/active-directory-federation-services)\nserver, the ADFS server could serve as your OpenID provider. You might also use\npublicly-reachable identity provider services such as Okta. Identity provider\ncertificates may be issued by either a well-known public certificate authority\n(CA), or by a private CA.\n| **Note:** The GKE Identity Service runs as a Pod inside the cluster control plane. During cluster lifecycle phases, the API Server is dynamically configured to use the in-cluster GKE Identity Service as the authentication webhook for all incoming requests. The API Server [isn't able to use in-cluster\n| DNS](https://github.com/kubernetes/minikube/issues/3772). As a result, the API Server is configured to access GKE Identity Service as a REST resource access. In audit logs, this invocation is recorded as a `CREATE` request to the Services or proxy resource by a `system:anonymous` user.\n\nFor an overview of how GKE Identity Service works, see [Introducing\nGKE Identity Service](/kubernetes-engine/enterprise/identity).\n\nIf you already use or want to use Google IDs to sign in to your GKE clusters\ninstead of an OIDC or LDAP provider, we recommend using connect gateway\nfor authentication. Find out more in [Connecting to registered clusters with the\nconnect gateway](/kubernetes-engine/enterprise/multicluster-management/gateway).\n\nBefore you begin\n\n- To prompt users for consent and authorize their user account, a\n browser-based authentication flow is used. Headless systems aren't\n supported.\n\n- To authenticate through the Google Cloud console, each cluster that you want to\n configure must be [registered with your project\n fleet](/kubernetes-engine/fleet-management/docs/fleet-creation).\n\nSetup process and options\n\nGKE Identity Service supports identity providers using the following\nprotocols:\n\n- [OpenID Connect (OIDC)](https://openid.net/connect/). We provide\n specific instructions for setup for some popular OpenID providers, including\n Microsoft, but you can use any provider that implements OIDC.\n\n- [Lightweight Directory Access Protocol\n (LDAP)](https://ldap.com/). You can use\n GKE Identity Service to authenticate using LDAP with Active Directory\n or an LDAP server.\n\nOIDC\n\n1. Register GKE Identity Service as a client with your OIDC provider\n following the instructions in [Configuring providers for\n GKE Identity Service](/kubernetes-engine/enterprise/identity/setup/provider).\n\n2. Choose from the following cluster configuration options:\n\n - Configure your clusters at fleet level following the instructions in\n [Configuring clusters for fleet-level\n GKE Identity Service](/kubernetes-engine/enterprise/identity/setup/fleet-cluster) (preview,\n Google Distributed Cloud version 1.8 and higher). With this option, your\n authentication configuration is centrally managed by Google Cloud.\n\n - Configure your clusters individually following the instructions in\n [Configuring clusters for GKE Identity Service with\n OIDC](/kubernetes-engine/enterprise/identity/setup/per-cluster). Because fleet-level setup is\n a preview feature, you may want to use this option in production\n environments, if you are using an earlier version of\n Google Distributed Cloud, or if you require GKE Identity Service\n features that aren't yet supported with fleet-level lifecycle\n management.\n\n3. Set up user access to your clusters, including role-based access control\n (RBAC), following the instructions in [Setting up user access for\n GKE Identity Service](/kubernetes-engine/enterprise/identity/setup/user-access).\n\nLDAP\n\nTo get started with LDAP, follow the instructions in [Set up\nGKE Identity Service with\nLDAP](/kubernetes-engine/enterprise/identity/setup/ldap).\n\nAccess clusters\n\nAfter GKE Identity Service has been set up, users can sign in to configured\nclusters using either the command line or the Google Cloud console.\n\n- Learn how to sign in to registered clusters with your OIDC or LDAP ID in\n [Accessing clusters using\n GKE Identity Service](/kubernetes-engine/enterprise/identity/accessing).\n\n- Learn how to sign in to clusters from the Google Cloud console in [Work\n with clusters from the\n Google Cloud console](/kubernetes-engine/fleet-management/docs/console)\n (OIDC only).\n\nTroubleshoot the login flow\n\nTo troubleshoot [login flows that authenticate directly on the\nGKE Identity Service server with a fully qualified domain name\n(FQDN)](/kubernetes-engine/enterprise/identity/setup/authenticate-fqdn-access),\nyou can use the GKE Identity Service diagnostic utility. The diagnostic\nutility simulates login flows with your OIDC provider to quickly identify\nconfiguration problems. This tool requires a version 1.32 or higher cluster and\nonly supports OIDC. For more information, see [GKE Identity Service\ndiagnostic\nutility](/kubernetes-engine/enterprise/identity/setup/anthos-v2-diagnostic-utility)."]]
