Create a 1st gen Cloud Run function by using the Google Cloud CLI
This page shows you how to create and deploy a 1st gen Cloud Run function using the Google Cloud CLI.
Before you begin
- Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
-
In the Google Cloud console, on the project selector page, select or create a Google Cloud project.
-
Make sure that billing is enabled for your Google Cloud project.
-
Enable the Cloud Functions and Cloud Build APIs.

- Prepare your development environment.
Need a command prompt? You can use the Google Cloud Shell. The Google Cloud Shell is a command line environment that already includes the Google Cloud CLI, so you don't need to install it. The Google Cloud CLI also comes preinstalled on Google Compute Engine Virtual Machines.

Change to the directory that contains the Cloud Run functions sample code:
Node.js
cd nodejs-docs-samples/functions/helloworld/
Python
cd python-docs-samples/functions/helloworld/
Go
cd golang-samples/functions/helloworld/
Java
cd java-docs-samples/functions/helloworld/helloworld/
C#
cd dotnet-docs-samples/functions/helloworld/HelloWorld/
Ruby
cd ruby-docs-samples/functions/helloworld/get/
PHP
cd php-docs-samples/functions/helloworld_get/
Take a look at the sample code:
Node.js
Python
Go
Java
C#
Ruby
PHP
Deploy a function
To deploy the function with an HTTP trigger, run the following command in the directory containing your function:
Node.js
gcloud functions deploy helloGET \ --runtime nodejs20 --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported Node.js version to run
your function.
Python
gcloud functions deploy hello_get \ --runtime python312 --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported Python version to run
your function.
Go
gcloud functions deploy HelloGet \ --runtime go121 --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported Go version to run
your function.
Java
gcloud functions deploy java-helloworld \ --entry-point functions.HelloWorld \ --runtime java17 \ --memory 512MB --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported Java version to run
your function.
C#
gcloud functions deploy csharp-helloworld \ --entry-point HelloWorld.Function \ --runtime dotnet6 --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported .NET version to run
your function.
Ruby
gcloud functions deploy hello_get --runtime ruby32 --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported Ruby version to run
your function.
PHP
gcloud functions deploy helloGet --runtime php82 --trigger-http
Use the --runtime
flag to specify the runtime ID of a
supported PHP version to run
your function.
You can optionally use the --allow-unauthenticated
flag to reach the function
without authentication.
This is useful for testing, but we don't recommend using this setting in
production unless you are creating a public API or website. Further, it might
not work for you, depending on your corporate policy settings. See
Authenticating for invocation for
details on how to invoke a function that requires authentication.
Test the function
When the function finishes deploying, take note of the
httpsTrigger
'surl
property or find it using the following command:Node.js
gcloud functions describe helloGET --format="value(httpsTrigger.url)"
Python
gcloud functions describe hello_get --format="value(httpsTrigger.url)"
Go
gcloud functions describe HelloGet --format="value(httpsTrigger.url)"
Java
gcloud functions describe java-helloworld --format="value(httpsTrigger.url)"
C#
gcloud functions describe csharp-helloworld --format="value(httpsTrigger.url)"
Ruby
gcloud functions describe hello_get --format="value(httpsTrigger.url)"
PHP
gcloud functions describe helloGet --format="value(httpsTrigger.url)"
It should look like this:
Node.js
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/helloGET
Python
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/hello_get
Go
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/HelloGet
Java
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/java-helloworld
C#
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/csharp-helloworld
Ruby
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/hello_get
PHP
https://GCP_REGION-PROJECT_ID.cloudfunctions.net/helloGet
Visit this URL in your browser. You should see a
Hello World!
message.
Delete the function
To delete the function, run the following command:
Node.js
gcloud functions delete helloGET
Python
gcloud functions delete hello_get
Go
gcloud functions delete HelloGet
Java
gcloud functions delete java-helloworld
C#
gcloud functions delete csharp-helloworld
Ruby
gcloud functions delete hello_get
PHP
gcloud functions delete helloGet
