Cloud Functions V2 API - Class Google::Cloud::Functions::V2::FunctionService::Client (v0.2.0)

Reference documentation and code samples for the Cloud Functions V2 API class Google::Cloud::Functions::V2::FunctionService::Client.

Client for the FunctionService service.

Google Cloud Functions is used to deploy functions that are executed by Google in response to various events. Data connected with that event is passed to a function as the input data.

A function is a resource which describes a function that should be executed and how it is triggered.

Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the FunctionService Client class.

See Configuration for a description of the configuration fields.

Yields

(config) — Configure the Client client.

Yield Parameter

config (Client::Configuration)

Returns

(Client::Configuration)

Example

# Modify the configuration for all FunctionService clients
::Google::Cloud::Functions::V2::FunctionService::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the FunctionService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields

(config) — Configure the Client client.

Yield Parameter

config (Client::Configuration)

Returns

(Client::Configuration)

#create_function

def create_function(request, options = nil) -> ::Gapic::Operation
def create_function(parent: nil, function: nil, function_id: nil) -> ::Gapic::Operation

Creates a new function. If a function with the given name already exists in the specified project, the long running operation will return ALREADY_EXISTS error.

Overloads

def create_function(request, options = nil) -> ::Gapic::Operation

Pass arguments to create_function via a request object, either of type CreateFunctionRequest or an equivalent Hash.

Parameters

request (::Google::Cloud::Functions::V2::CreateFunctionRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

def create_function(parent: nil, function: nil, function_id: nil) -> ::Gapic::Operation

Pass arguments to create_function via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

Parameters

parent (::String) — Required. The project and location in which the function should be created, specified in the format projects/*/locations/*
function (::Google::Cloud::Functions::V2::Function, ::Hash) — Required. Function to be created.
function_id (::String) — The ID to use for the function, which will become the final component of the function's resource name.

This value should be 4-63 characters, and valid characters are /[a-z][0-9]-/.

Yields

(response, operation) — Access the result along with the RPC operation

Yield Parameters

response (::Gapic::Operation)
operation (::GRPC::ActiveCall::Operation)

#generate_upload_url

def generate_upload_url(request, options = nil) -> ::Google::Cloud::Functions::V2::GenerateUploadUrlResponse
def generate_upload_url(parent: nil) -> ::Google::Cloud::Functions::V2::GenerateUploadUrlResponse

Returns a signed URL for uploading a function source code. For more information about the signed URL usage see: https://cloud.google.com/storage/docs/access-control/signed-urls. Once the function source code upload is complete, the used signed URL should be provided in CreateFunction or UpdateFunction request as a reference to the function source code.

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

Source file type should be a zip file.
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

And this header SHOULD NOT be specified:

Authorization: Bearer YOUR_TOKEN
