Deploying Cloud Functions

Deployment

Deployments work by uploading an archive containing your function's source code to a Google Cloud Storage bucket. You can deploy Cloud Functions from your local machine or from your GitHub or Bitbucket source repository (via Cloud Source Repositories). For details, see:

• Deploying from Your Local Machine
• Deploying from Source Control
• Deploying from GCP Console

When deploying, Cloud Functions looks for particular files, depending on your runtime. See the Node.js 6, Node.js 8, Python, and Go runtime overview pages for details.

Note: The first time you deploy a function it may take several minutes as we need to provision the underlying infrastructure to support your functions. Subsequent deployments will be much faster.

Building and Testing Locally

Cloud Functions execute in runtime environments based on open source languages and frameworks so you can build and test your functions locally using standard Node.js 6, Node.js 8, Python, and Go runtimes and development tools.

If your functions are written in Node.js, you can also use the Cloud Functions Node.js Emulator to run and debug your functions locally. This makes testing and debugging easier.

Note: Your use of the Cloud Functions Node.js Emulator is governed by the applicable open source license terms and not by the Google Cloud Platform License Agreement.
