Properties

Name Type Attributes Description

credentials

object

Credentials object.

Properties

Name	Type	Attributes	Description

email

string

Account email address. Required when using a .pem or .p12 keyFilename.

keyFilename

string

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.

The port on which to connect to the remote host.

projectId

string

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.

When uploading source code to the generated signed URL, please follow these restrictions:

Source file type should be a zip file.
Source file size should not exceed 100MB limit.
No credentials should be attached - the signed URLs provide access to the target bucket using internal service identity; if credentials were attached, the identity from the credentials would be used, but that identity does not have permissions to upload files to the URL.

When making a HTTP PUT request, these two headers need to be specified:

content-type: application/zip

Type	Description
Promise	The promise which resolves to an array. The first element of the array is Array of CloudFunction. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using `listFunctionsAsync()` method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.
