Quickstart: Deploy a Cloud Run function using the gcloud CLIThis page shows you how to deploy an HTTP Cloud Run function using the gcloud CLI.
Before you beginInstall the Google Cloud CLI.
Note: If you installed the gcloud CLI previously, make sure you have the latest version by runninggcloud components update
.If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.
To initialize the gcloud CLI, run the following command:
gcloud init
Create or select a Google Cloud project.
Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.Create a Google Cloud project:
gcloud projects create PROJECT_ID
Replace PROJECT_ID
with a name for the Google Cloud project you are creating.
Select the Google Cloud project that you created:
gcloud config set project PROJECT_ID
Replace PROJECT_ID
with your Google Cloud project name.
Verify that billing is enabled for your Google Cloud project.
Enable the Artifact Registry, Cloud Build, Cloud Run Admin API, and Cloud Logging APIs:
gcloud services enable artifactregistry.googleapis.com cloudbuild.googleapis.com run.googleapis.com logging.googleapis.com
Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/run.sourceDeveloper, roles/run.admin, roles/logging.viewer
gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE
Replace the following:
PROJECT_ID
: your project ID.USER_IDENTIFIER
: the identifier for your user account—for example, myemail@example.com
.ROLE
: the IAM role that you grant to your user account.Install the Google Cloud CLI.

PROJECT_ID
: your project ID.USER_IDENTIFIER
: the identifier for your user account—for example, myemail@example.com
.ROLE
: the IAM role that you grant to your user account.gcloud config set project PROJECT_IDReplace PROJECT_ID with the name of the project you created for this quickstart.
If you are under a domain restriction organization policy restricting unauthenticated invocations for your project, you will need to access your deployed service as described under Testing private services.
Make sure that you have the Service Account User role granted on the service identity. By default, the service identity is the Compute Engine default service account.
Grant the rolesTo grant access on the service identity resource, use the gcloud iam service-accounts add-iam-policy-binding
command, replacing the highlighted variables with the appropriate values:
gcloud iam service-accounts add-iam-policy-binding SERVICE_ACCOUNT_EMAIL \ --member="PRINCIPAL" \ --role="roles/iam.serviceAccountUser"
Replace the following:
PROJECT_NUMBER-compute@developer.gserviceaccount.com
SERVICE_ACCOUNT_NAME@PROJECT_ID.iam.gserviceaccount.com
Cloud Build automatically uses the Compute Engine default service account as the default Cloud Build service account to build your source code and Cloud Run resource, unless you override this behavior. For Cloud Build to build your sources, ask your administrator to grant Cloud Run Builder (roles/run.builder
) to the Compute Engine default service account on your project:
gcloud projects add-iam-policy-binding PROJECT_ID \ --member=serviceAccount:PROJECT_NUMBER-compute@developer.gserviceaccount.com \ --role=roles/run.builder
Replace PROJECT_NUMBER
with your Google Cloud project number, and PROJECT_ID
with your Google Cloud project ID. For detailed instructions on how to find your project ID, and project number, see Creating and managing projects.
Granting the Cloud Run builder role to the Compute Engine default service account takes a couple of minutes to propagate.
Note:The iam.automaticIamGrantsForDefaultServiceAccounts
organization policy constraint prevents the Editor role from being automatically granted to default service accounts. If you created your organization after May 3, 2024, this constraint is enforced by default.
We strongly recommend that you enforce this constraint to disable the automatic role grant. If you disable the automatic role grant, you must decide which roles to grant to the default service accounts, and then grant these roles yourself.
If the default service account already has the Editor role, we recommend that you replace the Editor role with less permissive roles.To safely modify the service account's roles, use Policy Simulator to see the impact of the change, and then grant and revoke the appropriate roles.
To write an application, follow these steps:
Node.jsCreate a new directory named helloworld
and change directory into it:
mkdir helloworld
cd helloworld
Create a package.json
file in the helloworld
directory to specify Node.js dependencies:
Create an index.js
file in the helloworld
directory with the following Node.js sample:
Create a new directory named helloworld
and change directory into it:
mkdir helloworld
cd helloworld
Create a requirements.txt
file in the helloworld
directory, to specify Python dependencies:
This adds packages needed by the sample.
Create a main.py
file in the helloworld
directory with the following Python sample:
Create a new directory named helloworld
and change directory into it:

Important: This quickstart assumes that you have owner or editor roles in the project you are using for the quickstart. Otherwise, refer to the Cloud Run Source Developer role for the required permissions for deploying a Cloud Run resource from source.
To deploy your Cloud Run function, follow these steps:
Deploy the function by running the following command in the directory that contains the sample code:
Node.jsgcloud run deploy nodejs-http-function \
--source . \
--function helloGET \
--base-image nodejs22 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
gcloud run deploy python-http-function \
--source . \
--function hello_get \
--base-image python313 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
gcloud run deploy go-http-function \
--source . \
--function HelloGet \
--base-image go124 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
Run the following command in the directory that contains the pom.xml
file:
gcloud run deploy java-http-function \
--source . \
--function functions.HelloWorld \
--base-image java21 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
gcloud run deploy ruby-http-function \
--source . \
--function hello_get \
--base-image ruby34 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
gcloud run deploy php-http-function \
--source . \
--function helloGet \
--base-image php84 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
gcloud run deploy csharp-http-function \
--source . \
--function HelloWorld.Function \
--base-image dotnet8 \
--region REGION \
--allow-unauthenticated
Replace REGION with the Google Cloud region of the service where you want to deploy your function. For example, europe-west1
.
When the deployment is complete, the Google Cloud CLI displays a URL where the service is running. Open the URL in your browser to see the output of your function.
Success: You deployed an HTTP Cloud Run function using the gcloud CLI.While Cloud Run does not charge when the service is not in use, you might still be charged for storing the container image in Artifact Registry. You can delete your container image or delete your Google Cloud project to avoid incurring charges. Deleting your Google Cloud project stops billing for all the resources used within that project.

URL, delete selected resources inside the project instead of deleting the whole project.If you plan to explore multiple architectures, tutorials, or quickstarts, reusing projects can help you avoid exceeding project quota limits.
Delete a Google Cloud project:
gcloud projects delete PROJECT_ID
