Implementa una función
En esta guía, se muestra cómo implementar una función a partir del código fuente con el comando gcloud functions. Para obtener información sobre cómo implementar una función con el comando gcloud run, consulta Implementa una función de Cloud Run con gcloud CLI.
El proceso de implementación toma tu código fuente y tu configuración y compila una imagen ejecutable que Cloud Run Functions administra de forma automática para controlar las solicitudes a tu función.
Conceptos básicos de la implementación
Para obtener una introducción sobre el tipo de funciones que puedes implementar, consulta Escribe Cloud Run Functions.
At the bottom of the Google Cloud console, a
Cloud Shell
session starts and displays a command-line prompt. Cloud Shell is a shell environment
with the Google Cloud CLI
already installed and with values already set for
your current project. It can take a few seconds for the session to initialize.
El primer argumento, YOUR_FUNCTION_NAME, es un nombre para tu función implementada. El nombre de la función debe comenzar con una letra seguida de un máximo de 62 letras, números, guiones o guiones bajos, y debe terminar con una letra o un número. El nombre del servicio de Cloud Run que se crea para tu función reemplazará los guiones bajos por guiones, y las letras mayúsculas se convertirán en minúsculas. Por ejemplo, a Function_1 se le asignará el nombre function-1 en Cloud Run.
La marca --region especifica la región en la que se implementará la función. Consulta Ubicaciones para obtener una lista de las regiones compatibles con Cloud Run.
La marca --runtime especifica el entorno de ejecución de lenguaje que usa tu función. Consulta Compatibilidad con el entorno de ejecución para obtener una lista de los IDs de entorno de ejecución compatibles.
La marca --source especifica la ubicación del código fuente de tu función.
La marca --entry-point especifica el punto de entrada a tu función en tu código fuente. Este es el código que se ejecutará cuando se ejecute tu función. El valor de esta marca debe ser un nombre de función o un nombre de clase completamente calificado que exista en tu código fuente. Para obtener más información, consulta Punto de entrada de la función.
Para especificar el activador de tu función, se requieren marcas adicionales (representadas como TRIGGER_FLAGS en el ejemplo anterior), según el activador que deseas usar:
Activa la función con Eventarc cuando se produce un
evento que coincide con los filtros especificados.
Para obtener una referencia completa del comando de implementación y sus marcas, consulta la documentación de gcloud functions deploy.
Para obtener más detalles sobre las marcas de configuración de gcloud functions deploy, consulta la documentación de Cloud Run.
Cuando la implementación finaliza correctamente, las funciones aparecen con una marca de verificación verde en la página de descripción general de Cloud Run en la Google Cloud consola.
La implementación inicial de una función puede tardar varios minutos, mientras se aprovisiona la infraestructura subyacente. Volver a implementar una función existente es más rápido, y el tráfico entrante se migra automáticamente a la versión más reciente.
URL del extremo HTTP
Cuando creas una función con el comando gcloud functions o la API de Cloud Functions v2, de forma predeterminada, la función tiene una URL de extremo HTTP cloudfunctions.net. Si tomas esta función y la implementas en Cloud Run, también recibirá una URL de extremo HTTP run.app. Sin embargo, las funciones creadas en Cloud Run no tendrán una URL de extremo HTTP cloudfunctions.net. La URL cloudfunctions.net y la URL run.app de una función se comportan de la misma manera. Son intercambiables y se usan para activar tu función.
Las funciones creadas con la API de Cloud Functions v2 (por ejemplo, con gcloud functions, la API de REST o Terraform) se pueden administrar con la API de Cloud Run Admin y la API de Cloud Functions v2.

To learn how to deploy a function using the\n`gcloud run` command, see\n[Deploy a Cloud Run function using the gcloud CLI](/run/docs/quickstarts/functions/deploy-functions-gcloud).\n\nThe deployment process takes your source code and configuration settings and\n[builds a runnable image](/functions/docs/building) that Cloud Run functions\nmanages automatically in order to handle requests to your function.\n\nDeployment basics\n-----------------\n\nFor an introduction on the type of functions you can deploy, see\n[Write Cloud Run functions](/run/docs/write-functions).\n\nUsers deploying functions must have the\n[Cloud Functions Developer](/functions/docs/reference/iam/roles#cloudfunctions.developer)\nIAM role or a role that includes the same permissions. See also\n[Additional configuration for deployment](/functions/docs/reference/iam/roles#additional-configuration).\n\n1. In the Google Cloud console, activate Cloud Shell.\n\n [Activate Cloud Shell](https://console.cloud.google.com/?cloudshell=true)\n\n\n At the bottom of the Google Cloud console, a\n [Cloud Shell](/shell/docs/how-cloud-shell-works)\n session starts and displays a command-line prompt. Cloud Shell is a shell environment\n with the Google Cloud CLI\n already installed and with values already set for\n your current project. It can take a few seconds for the session to initialize.\n2. Use the [`gcloud functions deploy`](/sdk/gcloud/reference/functions/deploy)\n command to deploy a function:\n\n ```sh\n gcloud functions deploy YOUR_FUNCTION_NAME \\\n --region=YOUR_REGION \\\n --runtime=YOUR_RUNTIME \\\n --source=YOUR_SOURCE_LOCATION \\\n --entry-point=YOUR_CODE_ENTRYPOINT \\\n TRIGGER_FLAGS\n ```\n\n The first argument, \u003cvar translate=\"no\"\u003eYOUR_FUNCTION_NAME\u003c/var\u003e, is a name for\n your deployed function. The function name must start with a letter\n followed by up to 62 letters, numbers, hyphens, or underscores, and must end\n with a letter or a number. The name of the Cloud Run service that\n is created for your function will replace underscores with hyphens and\n uppercase letters will be converted to lowercase. For example,\n `Function_1` will be given the name `function-1` in Cloud Run.\n | **Note:** Run `gcloud config set functions/gen2 true` to set all future first time deployments.\n - The [`--region`](/sdk/gcloud/reference/functions/deploy#--region) flag\n specifies the region in which to deploy your function. See\n [Locations](/run/docs/locations) for a list of regions supported by\n Cloud Run.\n\n - The [`--runtime`](/sdk/gcloud/reference/functions/deploy#--runtime) flag\n specifies which language runtime your function uses. See\n [Runtime support](/functions/docs/runtime-support) for a list of supported\n runtime IDs.\n\n - The [`--source`](/sdk/gcloud/reference/functions/deploy#--source) flag\n specifies the location of your function source code.\n\n - The [`--entry-point`](/sdk/gcloud/reference/functions/deploy#--entry-point)\n flag specifies the entry point to your function in your source code. This is\n the code that will be executed when your function runs. The value of this\n flag must be a function name or fully-qualified class name that exists in\n your source code. For more information, see\n [Function entry point](/run/docs/write-functions#function_entry_point).\n\n - To specify the [trigger](/sdk/gcloud/reference/functions/deploy#--trigger-bucket) for your\n function, additional flags (represented as\n \u003cvar translate=\"no\"\u003eTRIGGER_FLAGS\u003c/var\u003e above) are required, depending on\n the trigger you want to use:\n\n For a complete reference on the deployment command and its flags, see the\n [`gcloud functions deploy`](/sdk/gcloud/reference/functions/deploy)\n documentation.\n\n For more details about `gcloud functions deploy` configuration flags,\n refer to [Cloud Run documentation](/run/docs/configuring).\n\nWhen deployment finishes successfully, functions appear with a green check\nmark in the Cloud Run overview page in the\n[Google Cloud console](https://console.cloud.google.com/run).\n\nThe initial deployment of a function may take several minutes, while the\nunderlying infrastructure is provisioned. Redeploying an existing function\nis faster, and incoming traffic is automatically migrated to the newest version.\n| **Note:** Instances provisioned with a previous version of a function may continue running and processing traffic for several minutes after a new deployment has finished. This ensures that traffic sent to your function while a deployment is in progress isn't dropped. Also note that when a deployment fails, if there is a previous version of the function, it will continue to be available in most cases.\n\nHTTP endpoint URL\n-----------------\n\nWhen you create a function with the `gcloud functions` command or the\nCloud Functions v2 API, by default, the function has a\n`cloudfunctions.net` HTTP endpoint URL. If you take this function and deploy it\non Cloud Run, your function also receives a `run.app` HTTP endpoint\nURL. However, functions created in Cloud Run won't have an\n`cloudfunctions.net` HTTP endpoint URL. A function's `cloudfunctions.net` URL\nand `run.app` URL behave in exactly the same way. They are interchangeable,\nand are used to trigger your function.\n\nTerraform examples\n------------------\n\nFor examples about how to deploy functions using Terraform, see the\n[Terraform HTTP example](/functions/docs/tutorials/terraform) and\n[Terraform Pub/Sub example](/functions/docs/tutorials/terraform-pubsub).\n\nConfigure networking\n--------------------\n\nFunctions created using the [Cloud Functions v2 API](/functions/docs/apis)\n(for example, by using `gcloud functions`, the REST API, or Terraform) can be\nmanaged with the [Cloud Run Admin API](/run/docs/reference/cloud-run-admin-api-overview)\nas well as the Cloud Functions v2 API.\n| **Note:** If you created a Cloud Run function using `gcloud run` commands or the Cloud Run Admin API, you can't manage that function with `gcloud functions` commands or the Cloud Functions v2 API.\n\nTo learn more about managing networks for functions, including how to route\n[VPC network traffic](/run/docs/configuring/connecting-vpc), see\n[Best practices for Cloud Run networking](/run/docs/configuring/networking-best-practices).\n\nLearn how to deploy Cloud Run functions on Cloud Run\n----------------------------------------------------\n\nDeploying functions on Cloud Run is similar to the steps described in\nthis document, but with some added advantages:\n\n- You can use the Google Cloud console, as well as the gcloud CLI (`gcloud run deploy`).\n- The steps for specifying triggers are slightly different. To learn more, see [triggers and retries](/run/docs/functions/comparison#triggers_and_retries) and [examples of function triggers](/run/docs/function-triggers#triggers).\n- Cloud Run offers a broader array of configuration options:\n - [Minimum instances](/run/docs/configuring/min-instances)\n - [Concurrency](/run/docs/configuring/concurrency)\n - [Container configuration](/run/docs/configuring/services/containers)\n - [CPU limits](/run/docs/configuring/services/cpu)\n - [Memory limits](/run/docs/configuring/services/memory-limits)\n - [Request timeout](/run/docs/configuring/request-timeout)\n - [Secrets](/run/docs/configuring/services/secrets)\n - [Environment variables](/run/docs/configuring/services/environment-variables)\n - [Execution environment](/run/docs/configuring/execution-environments)\n - [HTTP/2](/run/docs/configuring/http2)\n - [Service accounts](/run/docs/configuring/services/service-identity)\n - [Cloud SQL connections](/run/docs/configuring/connect-cloudsql)\n - [Session affinity and traffic splitting](/run/docs/configuring/session-affinity#affinity-and-traffic-splitting)\n - [Tags](/run/docs/configuring/tags)\n - [Networking](/run/docs/configuring/networking-best-practices)"]]
