Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new Services client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::AppEngine::V1::Services::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::AppEngine::V1::Services::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Services client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the Services 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 configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#delete_service(request, options = nil) ⇒ ::Gapic::Operation #delete_service(name: nil) ⇒ ::Gapic::Operation

Deletes the specified service and all enclosed versions.

Examples:

Basic example

require "google/cloud/app_engine/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AppEngine::V1::Services::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AppEngine::V1::DeleteServiceRequest.new

# Call the delete_service method.
result = client.delete_service request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #delete_service(request, options = nil) ⇒ ::Gapic::Operation

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

    Parameters:

    • request (::Google::Cloud::AppEngine::V1::DeleteServiceRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #delete_service(name: nil) ⇒ ::Gapic::Operation

    Pass arguments to delete_service 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:

    • name (::String) (defaults to: nil) —

      Name of the resource requested. Example: apps/myapp/services/default.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

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

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

Examples:

Basic example

require "google/cloud/app_engine/v1"

# Create a client object. The client can be reused for multiple calls.

else
  puts "No response received."
end

Overloads:

  • #update_service(request, options = nil) ⇒ ::Gapic::Operation

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

    Parameters:

    • request (::Google::Cloud::AppEngine::V1::UpdateServiceRequest, ::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) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #update_service(name: nil, service: nil, update_mask: nil, migrate_traffic: nil) ⇒ ::Gapic::Operation

    Pass arguments to update_service 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:

    • name (::String) (defaults to: nil) —

      Name of the resource to update. Example: apps/myapp/services/default.

    • service (::Google::Cloud::AppEngine::V1::Service, ::Hash) (defaults to: nil) —

      A Service resource containing the updated service. Only fields set in the field mask will be updated.

    • update_mask (::Google::Protobuf::FieldMask, ::Hash) (defaults to: nil) —

      Required. Standard field mask for the set of fields to be updated.

    • migrate_traffic (::Boolean) (defaults to: nil) —

      Set to true to gradually shift traffic to one or more versions that you specify. By default, traffic is shifted immediately. For gradual traffic migration, the target versions must be located within instances that are configured for both warmup requests and automatic scaling. You must specify the shardBy field in the Service resource. Gradual traffic migration is not supported in the App Engine flexible environment. For examples, see Migrating and Splitting Traffic.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

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

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
